Arizona Diamondbacks outfielder Lourdes Gurriel Jr. (knee) will undergo surgery this Thursday to fix the torn ACL in his knee, according to Francys Romero. Gurriel is expected to be facing a nine- to 10-month recovery, which means he's not going to be ready for the start of the 2026 campaign. Depending on how his rehab goes, the 31-year-old veteran might be able to return just before the All-Star break in mid-July next year. He injured his knee back on Sept. 2 while trying to avoid a collision in the left-center gap with Blaze Alexander and had to be carted off the field. The Cuban outfielder was once again a solid source of power in 2025 in his third year in the desert before getting hurt, slashing .248/.295/.418 but with a career-low .713 OPS, 19 homers, 80 RBI, a career-high 10 steals, and 52 runs in 129 games played. Jake McCarthy should see most of the starts in left in Arizona the rest of the way.

Boston Red Sox rookie left-hander Payton Tolle will make the start on Wednesday in Sacramento against the hosting Athletics, according to manager Alex Cora. It will be Tolle's first time pitching on four days of rest this year, so Cora said the team will limit his pitch count. Left-hander Kyle Harris is also expected to join the BoSox and make his debut with the club on Wednesday, possibly as the bulk reliever behind Tolle. The 22-year-old southpaw will be making only his third major-league start and will not be a recommended streamer after surrendering five earned runs on five hits (two homers) while walking four and striking out two in just three innings in his latest start in Boston against the Arizona Diamondbacks on Sept. 5. MLB Pipeline has Tolle ranked as the team's No. 2 prospect, behind only shortstop Franklin Arias.

The Chicago Cubs recalled catching prospect Moises Ballesteros from Triple-A Iowa on Tuesday and placed outfielder Kyle Tucker (calf) on the 10-day injured list in a corresponding move with a left-calf strain, according to Taylor McGregor of Watch Marquee Sports. This will be the 21-year-old's fourth time coming up from the minors in his rookie season, but he has appeared in only six games while going 4-for-18 at the plate with six RBI and three runs scored. He is considered the team's No. 2 prospect, per MLB Pipeline, and was hitting an impressive .316/.385/.473 with an .858 OPS, 13 home runs, 76 RBI, 62 runs scored, and five steals in 114 games at Iowa. Ballesteros is considered the future at the position in Chicago, but he's unlikely to see much playing time down the stretch and isn't a realistic option to replace Tucker in right field.

The San Diego Padres announced on Tuesday that they have officially activated right-hander Michael King (knee) from the 15-day injured list and optioned right-handed reliever Alek Jacob to Triple-A El Paso in a corresponding move. King will make his return from the IL to face the Reds at Petco Park on Tuesday evening and will have much more risk than normal in starting fantasy lineups. The 30-year-old was San Diego's best pitcher to close out last season, but he's made only 11 starts in 2025 due to shoulder and knee injuries, including just one start since May 18. The Padres believe that four starts to close out the regular season for King will be enough for him to give them what they want if they make it to the postseason, but that doesn't mean he'll be very efficient in his first big-league start since Aug. 9. Tread carefully with King.

Los Angeles Dodgers catcher Will Smith (hand) is doing the catching for right-hander Emmet Sheehan on Tuesday and will hit cleanup in his return against the division-rival Colorado Rockies and right-hander German Marquez. Smith was hit by a pitch on his right hand last Wednesday against the Pittsburgh Pirates and missed the following five games with a contusion. The 30-year-old All-Star should now be returned to all starting fantasy lineups on Tuesday, even though he has hit only .211 with a .618 OPS, one home run, and two RBI in 19 career at-bats against Marquez. Fantasy managers will be hoping that the former first-rounder can pick up right where he left off before his hand injury, as he had gone 4-for-12 with a home run, two runs, and two RBI in the five games right before his injury. Smith is hitting just under .300 on the season with 17 homers and 61 RBI in 109 games.

Houston Astros starting pitcher Spencer Arrighetti (elbow) is scheduled to get a second opinion on his elbow later this week. It was announced last week that Arrighetti wouldn't require surgery on his injured elbow. It sounds like he'll avoid surgery, but the course of treatment seems unclear at the moment. Arrighetti hasn't pitched this month and is not expected to be back before the end of the regular season. The hope is that Arrighetti is ready for the beginning of the 2026 campaign. At this point, it seems safe for fantasy managers to drop Arrighetti and get another arm to help them.

Miami Marlins outfielder Kyle Stowers (oblique) has been shut down after suffering a setback during his minor-league rehab assignment. Stowers underwent additional imaging after dealing with some general soreness over the weekend. It has been announced that Stowers suffered a strained right side during a rehab game. The hope was that Stowers could return this week, but that seems unlikely now. The Marlins haven't given another timetable on his return, but it wouldn't be shocking to see Stowers be done for the season. The Marlins season isn't going anywhere, so they have little incentive to rush Stowers back to the field. For now, fantasy managers can continue to hold Stowers on their IR until the Marlins give an official timeframe on his return.

Chicago Cubs outfielder Kyle Tucker (calf) was placed on the 10-day injured list on Tuesday, retroactive September 6. Finally, the Cubs placed Tucker on the shelf after he missed the last five games due to a left calf strain. Tucker has been banged up with injuries throughout the second half of the season. At this point, it's the best decision to place Tucker on the shelf and give him time to get healthy. In a corresponding move, catcher Moises Ballesteros has been recalled to take over the active roster spot. The Cubs will likely use a committee approach to fill the void in the outfield. Willi Castro, Kevin Alcantara, and Seiya Suzuki figure to all see time in right field.

Kansas City Royals starting pitcher Michael Wacha (concussion) was placed on the 7-day concussion injured list on Tuesday. Wacha was scheduled to take the ball for Wednesday's game against the Cleveland Guardians, but that won't happen anymore. Wacha was involved in an off-the-field incident which will force him to miss some time. The right-hander is eligible to return on September 16. The Royals didn't announce who is going to take over his spot in the starting rotation. Fantasy managers should slide Wacha onto the IR and check back to see who will take the mound on Wednesday.

Kansas City Royals shortstop Bobby Witt Jr. (back) is returning to the starting lineup ahead of Tuesday's game against the Cleveland Guardians. Witt is back in the mix after missing three games due to lower back spasms. He underwent an MRI which didn't reveal any structural damage. That being said, Witt should be back to his normal MVP-type self here soon. He'll cover shortstop and bat second versus left-hander Joey Cantillo on Tuesday. Fantasy managers should make sure to check their lineups and get Witt in there ahead of first pitch.

From RotoBaller

Milwaukee Brewers first baseman Rhys Hoskins (thumb) has been activated from the 10-day injured list ahead of Tuesday's game against the Texas Rangers. Hoskins is back in the mix after missing over two months of action due to a left thumb sprain. This season, Hoskins is slashing .242/.340/.428 with 12 home runs and 42 RBI across 82 games. It'll be interesting to see how the Brewers handle first base with Andrew Vaughn playing well right now. The Brewers could use both of them and have one serve as the designated hitter. However, Christian Yelich would likely be pushed back into the outfield if they do that. Hoskins could lose some playing time down the stretch, but isn't worth rostering in anything more than deep leagues anyway.

Chicago Cubs outfielder Kyle Tucker (calf) remains sidelined for Tuesday's game at Truist Park against the Atlanta Braves. Willi Castro will make the start in right field and will hit seventh against Braves right-hander Spencer Strider. Left-calf tightness will sideline the left-handed hitting All-Star for the sixth straight game, and while the 28-year-old is still considered day-to-day, he could also land on the 10-day injured list any day now. Chicago's main priority at this point is to have Tucker be 100 percent healthy for the start of the postseason in October. If he cannot play by Friday's series opener against the Tampa Bay Rays after a scheduled day off on Thursday, an IL stint will be much more likely. The switch-hitting Castro has modest power/speed skills with 11 homers and 10 steals in 375 at-bats in 2025, but he's also hitting just .229.

Philadelphia Phillies outfielder Brandon Marsh (illness) remains under the weather and is out of Tuesday's starting lineup at Citizens Bank Park against the division-rival New York Mets. Marsh will miss his second straight game due to illness after sitting out the series-opening win on Monday. Weston Wilson will make the start in right field for the Phils and will bat seventh versus Mets left-hander Sean Manaea. With a right-hander scheduled to be on the mound on Wednesday, Marsh should be back in action if he's feeling better. The right-handed-hitting Wilson will be a deep DFS sleeper with limited upside on Tuesday's slate. The 30-year-old is batting only .219 (16-for-73) in limited action for the Phillies this year and has four homers, 13 RBI, and 10 runs. He's hitless in four career at-bats against Manaea.

Cleveland Guardians infielder Gabriel Arias (wrist) is being held out of the starting lineup on Tuesday against the division-rival Kansas City Royals after he left Monday's game early with right-wrist inflammation. Brayan Rocchio is starting at short and will bat seventh against Royals left-hander Noah Cameron. Arias is considered day-to-day for now and could be able to rejoin the lineup for the continuation of the series at Progressive Field on Wednesday. Daniel Schneemann is starting at the keystone and is batting eighth in the order. Neither Arias nor Rocchio is much to look at for fantasy purposes, so managers should have better sleeper options at shortstop for Tuesday's slate. The 24-year-old Rocchio is a switch-hitting, glove-first infielder who is batting .236 (67-for-284) on the season with a weak .635 OPS, four homers, 40 RBI, and six steals.

The Toronto Blue Jays announced on Tuesday that they placed shortstop Bo Bichette (knee) on the 10-day injured list (retroactive to Sept. 7) with a left-knee sprain and recalled outfielder Joey Loperfido from Triple-A Buffalo in a corresponding move. Bichette injured his knee while sliding on Saturday against the New York Yankees and then didn't play in the series finale on Sunday. The 27-year-old All-Star will now miss at least the next 10 days, although he might not be ready to return when eligible on Sept. 17. Losing Bichette down the stretch is a tough blow as the Jays try to win the American League East. With Bichette missing some time, expect the contact-oriented Ernie Clement to work as the regular shortstop in Toronto. He's at the 6 for Monday's series opener against the visiting Houston Astros and is hitting seventh in the batting order.

Philadelphia Phillies outfield prospect Justin Crawford (concussion) was placed on Triple-A Lehigh Valley's 7-day injured list with a concussion, retroactive to September 5, after colliding with third baseman Otto Kemp. The Phils' third-ranked prospect was having an excellent season for the Iron Pigs, slashing .334/.411/.452 with a .392 wOBA, 133 wRC+, and 46 stolen bases in 112 games. If he returns when first eligible, he could play an additional handful of games at Triple-A before the season is out, and could also join the Phillies for their stretch run. If he does not debut this year, it's a good bet he'll be in the majors in 2026, and he'll bring excellent bat-to-ball skills and a ton of speed with him, which will make him very intriguing for fantasy.

Los Angeles Dodgers outfield prospect Zyhir Hope is headed to Double-A Tulsa following a strong season at High-A Great Lakes. The Dodgers' second-ranked prospect (MLB No. 19) slashed .264/.377/.428 with 13 home runs and 26 steals in 121 games at High-A. The strikeout rate is something to keep an eye on at the next level, as he recorded an elevated 26.5 percent rate for the Loons, but it was somewhat offset by a strong 14.9 percent walk rate, and if he can continue to grow into additional power, then it may not matter all that much. The 20-year-old could be in the majors by 2027, and as a projected potential 30-home run hitter, he should be rostered already in dynasty leagues.

Boston Red Sox left-hander Kyle Harrison is traveling from Syracuse, New York, (where Triple-A Worcester is) to Sacramento to be an option for the big-league team on Wednesday in the series finale against the Athletics, according to Tommy Cassell. Boston has yet to announce a starter for Wednesday's contest, but it appears that both Payton Tolle and Harrison could be used in some capacity. The 24-year-old Harrison was expected to join the Red Sox recently, cut a minor ankle injury got in the way of those plans. He threw an inning with the WooSox on Sunday and could be used in bulk relief on Wednesday, although he wouldn't be recommended as a fantasy streamer. Harrison came over to Boston in the trade that sent Rafael Devers to San Francisco in the first half of the season, but he has yet to pitch with the BoSox.

Los Angeles Dodgers outfield prospect Josue De Paula is getting promoted to Double-A Tulsa for the remainder of the season. The Dodgers' top-ranked prospect (MLB No. 12) had a strong season at High-A, where he batted .263 with 12 home runs and a .421 slugging percentage. He also drew walks at an elite rate of 19.0 percent, buoying a phenomenal .406 on-base percentage, which also helped him steal 32 bases. The 20-year-old should move to within the top 10 prospects in all of baseball next year, and could even see a late-season call-up to the big leagues if everything goes right. With a solid all-around toolset, this year's All-Star Futures Game MVP should be stashed away in dynasty formats.

Detroit Tigers right-handed reliever Paul Sewald (shoulder) tossed a scoreless inning with a walk and three strikeouts in his second minor-league rehab appearance for High-A West Michigan on Sunday. Sewald has now thrown two scoreless innings in as many outings with a hit allowed, a walk and four strikeouts with West Michigan. The 35-year-old veteran has been working his way back from a right-shoulder strain that initially landed him on the injured list back on July 15. He was since moved to the 60-day IL, but he could return on or near Wednesday, Sept. 10, according to MLB.com. Sewald was acquired in a trade by Detroit this year, but he has yet to pitch for the Tigers because of his injury. Before injuring his shoulder, he had a bloated 4.70 ERA with 18 strikeouts in 15 1/3 innings for the Cleveland Guardians. Sewald should remain on the waiver wire in all leagues.
