An MRI exam on Monday showed that Minnesota Twins outfielder Byron Buxton (hip) is dealing with a right-hip impingement, according to Dan Hayes of The Athletic. Manager Derek Shelton said that Buxton is day-to-day. It explains why Buxton was held out of Monday's series opener in Houston against the Astros. The 32-year-old veteran center fielder doesn't appear to be dealing with a very serious injury, but fantasy managers should not be surprised if he's out for a second straight game in the second game of the series at Daikin Park on Tuesday. The two-time All-Star and 12-year veteran currently leads the American League with 25 home runs in 73 games across 329 plate appearances after clubbing a career-high 35 round-trippers, driving in 83, and stealing 24 bags in 126 games played in 2025. In addition to his 25 homers this year, Buxton has slashed .268/.325/.573 with an .898 OPS, 43 home runs, 56 runs, and seven steals for the Twins. His xBA of .249 and xwOBA of .351 (wOBA of .382) point to regression, but Buxton remains a must-hold in all fantasy formats. Hopefully, his hip injury won't lead him to the injured list just before the All-Star break in July.

Houston Astros shortstop Jeremy Pena (calf) will head to the 10-day injured list with a mild left-calf strain, manager Joe Espada told Chandler Rome of The Athletic. Espada said it should be a "minimum stint" on the IL. The Astros held Pena out of their starting lineup in Monday's series opener against the visiting Minnesota Twins, and now we know why. The good news is that the 28-year-old Dominican's injury isn't serious, and he could be back on July 10, just before the All-Star break next month, to face the Texas Rangers. Until then, both Nick Allen and Brice Matthews could split time at the 6 in Houston. Pena will head to the sidelines sporting a strong .295/.356/.443 slash line, .799 OPS, six home runs, 21 RBI,34 runs scored, and eight stolen bases across his 183 at-bats. It's been a trying 2026 season injury-wise, but when healthy, Pena has been consistent for fantasy managers, and he deserves to be stashed in most leagues while he rehabs. Pena's underlying metrics have been solid as well, as he sports a 37.6% hard-hit rate, 4% barrel rate, .297 xBA, and .345 xwOBA.

Philadelphia Phillies outfielder Brandon Marsh has been flexing his muscles all month, and that continued in Monday night's 11-7 loss to the visiting Pittsburgh Pirates at Citizens Bank Park. Marsh went 2-for-5 at the plate with two home runs and also struck out three times in the contest. The 28-year-old left-handed-hitting outfielder is now up to 14 homers on the season -- he's just three home runs shy of a new career high -- and he's up to a whopping nine round-trippers in June. In addition to his 14 homers, Marsh has 44 RBI in 80 games played and has become a must-add off the waiver wire for fantasy managers seeking more pop in their lineup. The former second-round selection by the Los Angeles Angels in 2016 came into Monday's contest against Pittsburgh with a .321/.353/.510 slash line, .863 OPS, 12 homers, 42 RBI, 46 runs scored, and eight stolen bases. Fantasy managers should expect some regression since he's basically playing every day and being exposed to more left-handed pitchers, but regardless, he's now rostered in nearly 80% of Yahoo leagues.

Seattle Mariners infielder/outfielder Brendan Donovan (groin) will be reevaluated after the team's current homestand and could be nearing a rehab assignment, per Ryan Divish of the Seattle Times. Donovan has been on the 10-day injured list since mid-May due to a left groin strain, but it appears he could be nearing a return around the All-Star break. Across 101 plate appearances in 2026 for Seattle, Donovan has hit .274/.386/.452 with three home runs, eight RBI, nine runs scored, and one stolen base. The 29-year-old does not offer much speed or power upside for fantasy managers, but he's a steady source of batting average when healthy. Seattle will have to shift some pieces around when Donovan returns, as the team's infield picture is crowded following the promotion of shortstop Colt Emerson to the big leagues. Still, Donovan's ability to play multiple positions should keep him in the Mariners lineup on a near-everyday basis once healthy.
