Seattle Mariners outfield prospect Lazaro Montes continues to show off his power stroke this season in the minors. Montes has eight homers and 18 RBI in August with Triple-A Tacoma and is up to 36 homers and 92 RBI between Double-A Arkansas and Tacoma this season. The left-handed hitter is the No. 5 prospect in the Mariners' system and has 65-grade power. Montes, signed out of Cuba, would offer nice power potential for fantasy teams if given a shot at promotion to Seattle. Fantasy managers can take a chance on Montes this season, but there is a good shot that he will not make his big-league debut until next season. At 21 years old, Montes could use a bit more minor league seasoning, but looks like a player who will make a big-time impact in the major leagues when he debuts.

Miami Marlins prospect Jonathon Long has four RBI and 14 runs scored in 13 games since joining Triple-A Jacksonville. Long was acquired by the Marlins from the Chicago Cubs at the trade deadline. In 99 games this season with Triple-A Iowa, Long hit .283 with 12 homers and 62 RBI to go with 67 runs scored. The 24-year-old infield/outfield prospect is the No. 19 prospect in the Marlins' system and has a 50-grade hit tool with 50-grade power. Long has the versatility to play either corner infield position along with the outfield, giving him a better shot at making his debut this season. With first baseman Kyle Stowers on the IL, that also gives Long a better shot at an MLB debut. The Marlins do have good outfield depth along with Javier Sanoja manning third base so Long will need to break through a bit for a big-league opportunity this season.

Cleveland Guardians prospect Ralphy Velazquez has hit three homers in his last four games at Triple-A Columbus in what has been a scorching hot month of August for the left-handed hitter. Velazquez has 11 homers and 20 RBI this month with a .356 batting average and 17 runs scored. The 21-year-old has split time this season between Double-A Akron and Columbus and combined to hit .288 with 24 homers and 74 RBI. Velazquez is the No. 2 prospect for Cleveland and has 60-grade power with a 50-grade hit tool. If Velazquez keeps hitting at this pace this month, he should get a chance for a promotion to Cleveland. The Guardians could use the power upside that Velazquez brings and he would be a welcome addition to many fantasy teams late this season.

Miami Marlins outfield prospect Cam Cannarella is hitting .250 this month at Triple-A Jacksonville with no homers and one RBI in what has been an August that has lacked power for the left-handed hitter. The 22-year-old has shown little power in his 25 games with Jacksonville, hitting .264 with one homer and four RBI. In High-A and Double-A combined prior to his promotion to Jacksonville, Cannarella combined to hit 12 homers with 51 RBI. The outfielder is the No. 6 prospect in the Marlins' system and has a 55-grade hit tool with 60-grade speed. Cannarella is likely a year or so away from a promotion to Miami, so he can best be left on waivers in redraft leagues and is more of a dynasty league target. Miami has a deep outfield at the big league level, so Cannarella is not likely to break through this season to make a fantasy impact.

Cleveland Guardians prospect Cooper Ingle is looking for another chance at the big leagues after a promotion earlier this season. At Triple-A Columbus, Ingle has had a decently productive month of August with two homers and nine RBI and a .236 batting average in 55 at bats. Ingle had 21 at bats in Cleveland when he was called up and produced just two hits with two RBI. In 82 games in Columbus this year, Ingle is hitting .305 with 18 homers and 61 RBI. The No. 5 prospect in the Guardians' system, Ingle has a 55-grade hit tool. Ingle has spent time at catcher and outfield as Cleveland has tried him out in left field to mixed results defensively. It looks unlikely that the Guardians will give Ingle another shot at the majors and he can be left on most waiver wires in redraft leagues.

Seattle Mariners prospect Michael Arroyo has adjusted nicely since his call up to Triple-A Tacoma. In 36 games with the Rainiers, Arroyo has hit .275 with seven homers and 30 RBI with 29 runs scored. The infield prospect comes in at No. 3 on the Mariners updated prospect list and has a 55-grade hit tool with 55-grade power and 50-grade speed. Signed out of Colombia, Arroyo has fared well in his minor-league career and has one more step to go in his progression to complete the journey to the MLB. At age 21, Arroyo is worth taking a chance on in fantasy leagues as the right-handed hitter could see a call up to Seattle before the end of this season. He likely needs a bit more time in Triple-A to adjust, but the Mariners could reward the youngster with a promotion soon.

San Francisco Giants outfield prospect Bo Davidson has homers in two straight games in the middle of a powerful month of August at Triple-A Sacramento. In 68 August at bats, Davidson has six homers and 22 RBI while hitting .382. In 31 games since his promotion to Triple-A, the 24-year-old is hitting .315 with six homers and 26 RBI. Davidson, the No. 8 prospect for the Giants, is a nice five-tool player with the 55-grade power and speed combination. He had 14 stolen bases at Double-A Richmond prior to his promotion to Sacramento. At 24 years old Davidson is the right age for a chance at the major leagues and his power-speed combo makes him an appealing fantasy addition. But it might not be until next season that fantasy managers are able to see his debut.

Toronto Blue Jays first baseman Vladimir Guerrero Jr. (concussion) made his return from the seven-day concussion injured list on Saturday and was starting at first base and batting out of the two-hole for the start of Saturday's contest in the Bronx against the division-rival New York Yankees and left-hander Ryan Weathers, per MLB.com. Guerrero has been cleared after going 1-for-1 with two walks in a single minor-league rehab game with Single-A on Thursday. Fantasy managers are hoping that the 27-year-old Canadian slugger can turn his season around in the final month-plus after an especially disappointing 2026 that has seen him hit just .263/.337/.356 with a .693 OPS, seven home runs, 46 RBI, 61 runs scored, and seven stolen bases across his 430 at-bats. Vladdy's drop in power has been the most concerning and head-scratching of all. Going into Saturday's game against the Yanks, Guerrero has hit .244 (11-for-45) with a homer, a double, two RBI, and six runs scored in 11 games so far in August.

Washington Nationals middle infielder CJ Abrams (ankle) is missing a third straight game on Saturday against the division-rival Miami Marlins due to a left-ankle injury that he suffered in the ninth inning of Wednesday's game against the Texas Rangers, per MLB.com. Abrams is considered day-to-day for now, but if he is unable to return for the weekend series against Miami, the Nats could be forced to send him to the 10-day injured list next week. Nasim Nunez is starting at shortstop and batting ninth, while Jose Tena will man the keystone and hit sixth on Saturday against Marlins right-hander Eury Perez. Abrams, who recently was asked to move from shortstop to second base, is having a breakout 2026 campaign offensively, hitting .279/.354/.530 with an .884 OPS, 29 home runs, 91 RBI, 24 stolen bases, and 77 runs scored across 124 games and 534 plate appearances. He has already set career highs in home runs and RBI in his fifth year in the big leagues. Fantasy managers would really love to get good news that he will be ready to return for Sunday's series finale in Miami.

Washington Nationals infield prospect Seaver King is red-hot at Triple-A Rochester with five homers in his last six games and eight homers and 15 RBI during the month of August while hitting .394. In 51 games since his promotion to Rochester, King is hitting .320 with 13 homers and 41 RBI to go with nine stolen bases. The talented middle infielder hit .336 at Double-A Harrisburg prior to his promotion, but has battled injuries this season. King is the No. 4 prospect for the Nationals out of Wake Forest and boasts 70-grade speed. Likely to be a big-time five-category producer at the major league level, King could get a look this season, but the Nationals have been hesitant to give him a promotion. With CJ Abrams and Nasim Nunez manning shortstop and second base respectively it is unlikely for King to get the call this year, but if he keeps up the power stroke he could force his way to a promotion.

Seattle Mariners right-hander Bryan Woo (shoulder) has been pushed back from this weekend's series against the Chicago Cubs due to discomfort in his right shoulder, according to Daniel Kramer of MLB.com. It is to be determined when he will make his next start, although manager Dan Wilson sounded optimistic that Woo will avoid a trip to the injured list. With Woo sidelined for now, the Mariners are calling up top left-handed pitching prospect Kade Anderson for his major-league debut on Saturday. Right-hander Bryce Miller will get the nod in the series finale on Sunday. Woo was pulled from his last start early last Sunday against the division-rival Houston Astros with something bothering his right shoulder, and the Mariners are going to play it safe and hold him out this weekend. Check back to see if the M's clear him to pitch in their upcoming series against the Philadelphia Phillies, which starts on Monday at T-Mobile Park. Woo finished off July by allowing 10 earned runs with 13 strikeouts and four walks in 10 innings in two starts against the Texas Rangers and Los Angeles Dodgers, but in his three starts so far in August, he's given up only two earned runs with three walks and 15 strikeouts in 18 innings versus the Detroit Tigers, New York Yankees, and Astros.

Minnesota Twins top prospect Walker Jenkins is producing nicely this month at Triple-A St. Paul with five homers and eight RBI while hitting .379. Jenkins missed a large portion of the beginning of the season with a Grade 2 AC joint sprain in his left shoulder. That injury set him back in his timeline for advancing to the major leagues and he still is looking to prove full health to his organization. Jenkins was a first-round pick in 2023 and has advanced nicely in the minor leagues. At age 21, he is primed for a shot at the big leagues with a 60-grade hit tool, 60-grade power, and 55-grade speed. The left-handed hitter has hit well in limited action at St. Paul this season with nine homers and 23 RBI in 65 games at the Triple-A level with a .294 batting average. Jenkins is looking for an opening to let him play in Minnesota and he will be a big asset for fantasy managers if given the chance.

Los Angeles Dodgers manager Dave Roberts said that he expects outfielder Andy Pages (hand) to miss four to five weeks with a fractured left hand, which means he will not be available until just before the start of the postseason, according to Bill Plunkett of The Orange County Register. Pages was hit by a pitch in the early stages of Friday's game against the Pittsburgh Pirates and will now miss extended time. With the right-handed slugger now out for pretty much the rest of the regular season, the Dodgers will most likely use a platoon in center field, with Alek Thomas facing right-handers and Tommy Edman facing lefties. It's a tough blow for fantasy managers, as Pages was hitting a strong .272/.338/.358 with a career-best .797 OPS, 21 home runs, 80 RBI, 12 stolen bases, and 72 runs scored in 128 games for the Dodgers in his third year in the big leagues. Fantasy managers in redraft leagues would not be crazy to drop him at this juncture, as even if he does make it back in late September, Pages might only play in a handful of games, at most.

Colorado Rockies first base/outfield prospect Charlie Condon has cooled off significantly at Triple-A Albuquerque over the past month. In August, the 23-year-old is hitting just .190 with two homers and nine RBI. Condon was passed up for promotion as teammate Zac Veen joined the Rockies, and Condon has struggled since then. It's a major downturn this month for Condon, who has 22 homers and 74 RBI this season at Albuquerque in 105 games while hitting .270. Condon is the No. 3 prospect for the Rockies and has a 55-grade hit tool with 55-grade power. The Georgia product could still please fantasy managers if given a call-up to the Rockies and Coors Field. If he joins Veen in Colorado, Condon could still be very productive despite his recent struggles.

Seattle Mariners pitching prospect Kade Anderson will make his major league debut on Saturday against the Chicago Cubs and the left-hander is talented enough to win leagues for fantasy managers. Anderson was called up from Double-A Arkansas to make his start on Saturday and he did nothing to disappoint while with the Travelers. He compiled a 10-1 record with a 1.06 ERA and 0.64 WHIP to go with 135 strikeouts in 93 1/3 innings pitched. The top overall prospect for the Mariners, Anderson is considered one of the best pitching prospects in all of baseball. The 22-year-old boasts a 60-grade fastball and changeup combination to go with a 55-grade curveball and slider. The 2025 first-round draft pick rose through the minors seemingly easily to make his MLB debut and he has the stuff to reward fantasy managers who stashed him.

Arizona Diamondbacks second baseman Ketel Marte (knee) was seen at a casino during the team's game on Friday night against the Cincinnati Reds. "He's free to do whatever he wants as long as he wakes up tomorrow and gets his work done at Salt River (Fields), which I am certain he will, that's all that matters right now," manager Torey Lovullo said when asked about Marte being at a casino, per Cameron Cox of 12 News. Marte was a no-show for the series opener in Boston against the Red Sox earlier this week, which prompted the D-backs to place the 32-year-old All-Star on the restricted list. Then we found out that Marte headed back to Arizona for an MRI exam on his left knee without telling the team. He was placed on the 10-day injured list on Thursday, with general manager Mike Hazen saying that he expects Marte to rejoin the team following his stint on the IL. It is unclear how long Marte will be sidelined with left-knee inflammation, but he needs to be stashed in all fantasy leagues until he returns. In the meantime, Ildemaro Vargas should continue to serve as the team's primary second baseman.

According to Alex Pavlovic, San Francisco Giants infielder Marcelo Mayer (forearm, foot) has paused his rehab assignment due to a bone bruise in his right foot. The plan is for Mayer to rest through the weekend before being re-evaluated next week. He originally landed on the Injured List in late June with a left forearm stress reaction. Now, he'll need to hold off on his rehab assignment for a few days while he recovers from this foot injury. Mayer was nearing a return to the Giants, so hopefully this won't set him back too far. Fantasy managers should check back for an update on his status after he is re-evaluated.

Chicago Cubs relief pitcher Daniel Palenica (elbow) was activated off the 60-day Injured List ahead of Friday's game against the Seattle Mariners, Taylor McGregor reports. Palenica is officially back in the mix after being sidelined since mid-June due to an elbow issue. When healthy, Palencia has posted a 2.70 ERA, 1.38 WHIP, and a 19/6 K/BB ratio across 16.2 innings of work in 19 appearances. Jacob Webb was pitching well as the closer while Palencia was out, but he'll move out of that role now. Fantasy managers looking for a source of saves should snag Palencia off the waiver wire before it's too late. In a corresponding move, right-hander Javier Assad was optioned to Triple-A Iowa on Friday

Seattle Mariners starting pitcher Bryan Woo won't make his scheduled start against the Chicago Cubs this weekend. According to Adam Jude, Woo will be pushed back from his scheduled outing on Sunday. Instead, Kade Anderson will get the ball on Saturday, while Bryce Miller gets the starting nod for Sunday's series finale. Woo was removed early during his most recent start against the Houston Astros due to shoulder soreness. It sounds like Woo is still dealing with some soreness, but is expected to be worked into the rotation at some point next week. At the moment, there are no plans to have Woo placed on the Injured List, but it shouldn't be completely ruled out. Fantasy managers should check back for another update on Woo next week.

Seattle Mariners top pitching prospect Kade Anderson is scheduled to make his season debut against the Chicago Cubs on Saturday. Anderson has earned a late-season call-up after posting fantastic numbers during his lone season in the minor leagues. The Mariners selected Anderson as the third overall pick during the 2025 June Amateur Draft. During his first year in Double-A Arkansas, Anderson posted a 1.06 ERA, 0.64 WHIP, and a 135/13 K/BB ratio across 93.1 innings of work. The 22-year-old is clearly ready to be promoted above Double-A, but the Mariners feel he's ready for the big leagues after 18 starts in the minors. Given his numbers, Anderson is a must-add player ahead of his big league debut versus the Cubbies on Saturday.
