Tampa Bay Rays outfielder Jake Mangum was in the thick of the action in Monday's 10-8 extra-inning win over the Red Sox. Mangum went 4-for-6 with four singles, two RBI, and a strikeout. The 29-year-old has come out of nowhere to be a surprising fantasy contributor as a late-blooming rookie, slashing .302/.333/.368 with one home run, 15 RBI, and 10 stolen bases in 112 plate appearances. He missed a little over a month with a left groin strain but has seen playing time and has provided batting average and speed, facets he also provided throughout his minor-league career. Mangum is currently rostered in just five percent of leagues, meaning he is likely available even in deep roto leagues where he could provide solid value.

St. Louis Cardinals closer Ryan Helsley blew his fifth save of the season in Monday's 5-4 extra-inning loss to the Blue Jays. Helsley came in to pitch the top of the ninth inning up by one. He got the first out on a pop-out, allowed a game-tying solo homer, got the second out on a strikeout, allowed a double, and ended the inning with another strikeout. The 30-year-old, who was a National League All-Star last season, has already tied his career high in blown saves this season. He has notched 13 saves with a 3.75 ERA, a 1.54 WHIP, a 10.50 K/9 rate, and a 4.50 BB/9 rate in 24 innings of work. His walk rate has been an issue and he has allowed harder contact than in previous seasons, contributing to his bloated WHIP and ERA. The good news for fantasy managers is that Helsley still appears to have a firm grasp on the role, but he will need to start tightening things up.

Toronto Blue Jays closer Jeff Hoffman picked up his 16th save of the season in Monday's 5-4 extra-inning win over the Cardinals. Hoffman came in to pitch the bottom of the 10th inning up by one with an automatic runner on second. He shut the door with a 1-2-3 performance, including a strikeout. The 32-year-old has been erratic overall in his first season with the Blue Jays, converting 16 of 19 save opportunities with a 5.46 ERA, a 1.08 WHIP, and a 13.04 K/9 rate in 29 2/3 innings of work. The good news for fantasy managers is that Hoffman appears to have the confidence of the Blue Jays coaching staff and his underlying metrics look strong overall, so he should continue to see opportunities to provide fantasy value.

Boston Red Sox top prospect Roman Anthony caused plenty of fanfare but did not contribute much to the action in Monday's 10-8 extra-inning loss to the Rays. The 21-year-old, who is the No. 1 overall prospect in all of baseball per MLB Pipeline, made his big-league debut in right field batting fifth. He went 0-for-4 with an RBI, a walk, and a strikeout. Anthony performed very well in the minors last season. He was also slashing .288/.423/.491 with Triple-A Worcester before getting the call-up, so there is plenty for fantasy managers to be excited about. He is already rostered in 62 percent of leagues, but that means he could still be available for some fantasy managers.

Pittsburgh Pirates outfielder Bryan Reynolds did his part offensively in Monday's 10-3 win over the Marlins. Reynolds went 2-for-5 with a single, a triple, and three RBI. The 30-year-old broke a 1-1 tie in the third inning, lacing a Eury Perez breaking pitch into the right-center gap to clear the bases. It was a bright spot for Reynolds in a season that has uncharacteristically had few so far. While Reynolds usually provides a high fantasy floor, he has slashed just .238/.311/.385 with eight home runs, 39 RBI, and three stolen bases in 283 plate appearances. His counting stats are relatively in line with how he has produced over the past several seasons, but hopefully, he can get his batting average up toward his .273 career mark.

Miami Marlins starting pitcher Eury Perez (elbow) did not have the best results in his 2025 season debut, taking the loss in a 10-3 game against the Pirates. Perez pitched three innings, allowing four runs on four hits and two walks with five strikeouts on 70 pitches. The 22-year-old had Tommy John surgery on his right elbow in April of last year and hadn't appeared in an MLB regular-season game since September of 2023. While the box score wasn't great, it was encouraging to see Perez back on the mound for the Marlins topping out at 99.7 MPH. Perez looked great from a fantasy perspective in 2023 and had success in his minor-league rehab assignment this season, but fantasy managers will need to be patient as he gets back into the swing of things. His next scheduled start will be a decent matchup at the Nationals.

Philadelphia Phillies infield/outfield prospect Otto Kemp recorded his first major league hit on Monday, finishing with three hits in the game in five at-bats, and he scored once in the 4-3 extra-innings win over the Cubs. The 25-year-old went hitless in his first five at-bats in the bigleagues, and we'll see how he performs going forward now with some confidence under his belt. The Phils' 24th-ranked prospect was on fire prior to his call-up, slashing .313/.416/.594 with 14 home runs and 11 steals in 58 games. Kemp was called up when Bryce Harper (wrist) hit the IL, but if he continues to hit, Philadelphia may have some tough decisions to make when Harper returns. As for fantasy, Kemp could be a speculative add for his power and ability to steal bases in deep leagues, especially given his eligibility at both 3B and 2B on Yahoo!.

Atlanta Braves starting pitcher Chris Sale was dialed in for Monday's 7-1 win over the Brewers. Sale pitched seven innings, allowing one run on five hits and two walks with a season-high 11 strikeouts. The 36-year-old has shown no signs of slowing down after earning the National League Cy Young Award last season. He has been excellent in his first two seasons with the Braves after an up-and-down tenure with the Red Sox. Sale is now 4-4 with a 2.79 ERA, a 1.21 WHIP, and an 11.94 K/9 rate in 14 starts and 80 2/3 IP. His next start will be an excellent matchup against the Rockies at home.

Milwaukee Brewers shortstop prospect Cooper Pratt went 3-for-4 with an RBI, a run scored, and stole two bases on Sunday for Double-A Biloxi. After slashing .265/.346/.404 over his first 35 games, the 20-year-old went into a 7-for-59 (.119) funk over his next 16 contests. The 6-foot-3 slugger is now slashing .231/.314/.342 for the year after his three-hit game, with 10 doubles, four home runs, and 12 steals. The Brewers will likely want to see a continuation of Sunday's performance for a while before considering pushing him to Triple-A, and Milwaukee's third-ranked prospect, who has solid all-around tools, has an MLB ETA of 2027 per MLB.com.

Minnesota Twins first base prospect Aaron Sabato took home Texas League Player of the Week honors for his performance at Double-A Wichita last week. Over six games, the 26-year-old went 10-for-24 (.417) with five doubles, three home runs, 10 RBI, seven runs scored, and he even stole one base. A 2020 first-round draft pick, Sabato struggled to a .209 batting average and .743 OPS with a 31.6 percent strikeout rate through the end of 2024, but looks to have finally begun to find his swing in 2025. An oblique injury delayed the start of his Double-A season until April 15, but through 37 games for the Wind Surge, the right-handed slugger has produced a .311 batting average with eight home runs and an improved 26.6 percent strikeout rate. What has always been a constant is a double-digit walk rate, and his 13.0 percent BB% has helped him to a strong .409 OBP so far this season. The UNC product could get a shot at Triple-A later this year, and he brings a powerful bat, so the Twins will want to see him finish strong if he's going to be in their 2026 plans.

Athletics left-hander Brady Basso (shoulder) felt good after throwing an inning with Single-A Stockton during a minor-league rehab outing on Sunday, according to MLB.com's Martin Gallegos. The A's are looking at using him in a relief role, which could get him back to the big leagues quicker. Basso is currently on the 60-day injured list and has yet to pitch in the big leagues this year due to his shoulder injury, but he could be an option out of their bullpen before the All-Star break. The 27-year-old southpaw made his MLB debut with the A's last year and posted a 4.03 ERA (3.88 FIP) and 1.25 WHIP with 19 strikeouts and five walks in seven outings (four starts) over 22 1/3 innings. Basso relies on command and doesn't have strikeout stuff, so he certainly won't be in play in mixed fantasy leagues when he returns to the majors in 2025.

Philadelphia Phillies outfielder Brandon Marsh hit a bases-loaded single in the bottom of the 11th inning to send the Phillies to a 4-3 win over the Cubs on Monday. He actually entered the game as a pinch hitter initially, and collected two singles in his three at-bats. While it'll go down as a single on the stat sheets, the ball was a rocket to the warning track that would have been a double if it hadn't won the game. Hopefully this is the spark that the 27-year-old needed to get going, as he's slashed just .228/.331/.325 on the season. The one silver lining of his profile has been a 13.4% walk rate, which has kept his on-base percentage manageable during the slump.

Athletics third baseman Gio Urshela (hamstring) is expected to begin a rehab assignment this week, reports Martin Gallegos of MLB.com. He has been on the injured list since May 23 with a left hamstring strain. A few weeks off isn't that long in the grand scheme of things, so he should be able to progress quickly and return to the major league lineup next week. It's not clear how much playing time Urshela will get once he is activated, as there's about to be a logjam between him, Luis Urias, Max Muncy, and Zack Gelof once he is also healthy.

Athletics second baseman Zack Gelof (ribs) is expected to begin a rehab assignment this week, Martin Gallegos of MLB.com reports. He's already had to fight through multiple injuries in 2025, as the stress fracture in his ribs occurred while on a rehab stint to recover from hamate bone surgery that he underwent in March. The 25-year-old will fit in nicely with a young Athletics lineup that is taking a huge step forward this year. The youngster is coming off of a 2024 season where he hit 17 home runs and stole 25 bases, and his power could play up even more in Sutter Health Park. However, it also wouldn't be surprising if he struggled out of the gate, as the recovery from hamate bone surgery has a reputation for sapping power from hitters. Only time will tell but expect to see Gelof activated by the end of the month.

Los Angeles Dodgers starting pitcher Tyler Glasnow (shoulder) is back to throwing off the mound after a brief shutdown due to back soreness, reports Bill Plunkett of The Orange County Register. The ace has been on the injured list since April 27 due to shoulder inflammation, so the back soreness that popped up wasn't considered to be serious. Once he does start a minor league rehab stint in the coming weeks, it likely won't be as long as teammate Blake Snell's, since Glasnow was able to get four full starts under his belt before suffering the injury. In those 18 innings, the right-hander posted a 4.50 ERA and 1.28 WHIP.

Minnesota Twins starting pitcher Simeon Woods Richardson is expected to be called back up to join the major league rotation on Tuesday, reports Ari Alexander of KPRC 2 Houston. With Pablo Lopez and Zebby Matthews both going on the injured list, it leaves a spot for the 24-year-old to face off against the Rangers. He'll be looking to turn his season around, considering he posted a 5.02 ERA and 1.54 WHIP in 37 innings earlier in the season. It's not likely the youngster will be fantasy-relevant, considering even in Triple-A he allowed eight runs over 17 innings.

Los Angeles Dodgers starting pitcher Blake Snell (shoulder) is set to throw a bullpen session on Tuesday, reports Bill Plunkett of The Orange County Register. This will be a significant step in his rehab process, as the lefty recovers from shoulder inflammation that has sidelined him since April 2. The 32-year-old made it this far in his recovery last month too, but was shut down when his first bullpen session caused further inflammation. The extended absence means the two-time Cy Young winner still has a long road ahead that will include many rehab starts.

Cleveland Guardians infield prospect Juan Brito (thumb) is tracking toward playing in the rookie-level Arizona Complex League this week as he works his way back from surgery on his right thumb back in late April to fix a torn ligament, according to MLB.com's Tim Stebbins. Brito, the team's No. 10 prospect per MLB Pipeline, was hitting .291/.406/.491 with an .897 OPS, two home runs, 10 RBI, 11 runs scored and four stolen bases in 16 games with Triple-A Columbus before landing on the seven-day minor-league injured list. The 23-year-old Dominican switch-hitter is nearing a return to minor-league action and could be a candidate to make his major-league debut later this season if he continues to hit the ball well upon his return. Brito never showed much power until last year, when he hit 21 bombs in 144 games. Fantasy-wise, Brito won't have a very high ceiling with fringy speed and questionable power at second base.

MLB.com's Tim Stebbins reports that Cleveland Guardians right-hander Trevor Stephan (elbow) will start a minor-league rehab assignment on Tuesday in the rookie-level Arizona Complex League. Stephen is attempting to return from Tommy John surgery that kept him out of action for the entire 2024 season. Because of how long he's been out, the 29-year-old should require a lengthy rehab assignment and probably won't be an option at the big-league level until after the mid-July All-Star break. When he's finally ready to return, Stephen will join Cleveland's bullpen and won't have any fantasy value in most leagues. He went 7-7 in 2023 with a 4.06 ERA (3.56 FIP), a 1.29 WHIP, two saves, 75 strikeouts and 26 walks in 71 relief appearances in 2023, one season after posting a career-low 2.69 ERA with three saves in 63 2/3 innings.

San Diego Padres right-hander Michael King (shoulder) is continuing to rest and gather information about his shoulder injury, Dennis Lin of The Athletic reports. "We're just in a holding pattern to see what it is and the best way to treat it, if there is a better way to treat it outside of just the rest," manager Mike Shildt said. The Padres have been without King since inflammation forced him to the 15-day injured list on May 25 (retroactive to May 22). The loss of King has been significant for the Padres and fantasy managers alike. He stormed out of the gates this year with a 2.59 ERA and 64 strikeouts against 17 walks in 55 2/3 innings before going on the shelf. Unfortunately, it doesn't appear his return is imminent.
