Houston Astros outfielder Chas McCormick (hamstring), who was not activated from the injured list ahead of Monday's series opener against the division-rival Los Angeles Angels, should re-enter Houston's lineup "soon." After finishing his minor-league rehab assignment with Double-A Corpus Christi on Sunday, McCormick went through pregame workouts on Monday and should be reinstated from the IL sometime this week. The 29-year-old outfielder broke out with 22 home runs and 19 stolen bases a year ago, but he was slashing a feeble .236/.325/.278 with three extra-base hits, eight RBI, and two steals over 83 plate appearances (21 games) before going down with discomfort in his right hamstring. Top prospect Joey Loperfido is batting an encouraging .333 (13-for-39) with one homer, five RBI, and one pilfer through 13 outings with the Astros, but he'll be in line to lose playing time when McCormick returns.

Boston Red Sox starting pitcher Garrett Whitlock (oblique, elbow) has ligament damage in his right elbow, and surgery has become a real possibility. Whitlock was originally expected to return to Boston's rotation on Monday after being sidelined by a strained left oblique, but he experienced soreness in his elbow following last week's minor-league rehab appearance and now appears to be staring at a potentially season-ending setback. It would be a big blow to the Red Sox' pitching staff after the 27-year-old right-hander put together a promising 1.96 ERA and 1.15 WHIP with 17 strikeouts and seven walks across 18 1/3 innings (four starts) in 2024. Whitlock will be evaluated by a doctor in Alabama for a second opinion later this week. In the meantime, righty Cooper Criswell looks set to continue handling a rotation spot going forward.

Los Angeles Dodgers starting pitcher Bobby Miller (shoulder) will pitch in another simulated game on Tuesday at Dodger Stadium. Miller threw two simulated innings last Wednesday, and the hope is that a brief minor-league rehab assignment is the next step following Tuesday's session. The 25-year-old flame-throwing right-hander is working his way back from inflammation in his right shoulder, and despite giving up seven runs over 11 2/3 innings before the injury this season, his 18:6 K:BB and elite strikeout upside make him a must-stash fantasy asset with a late-May or early-June return being the expectation. In Miller's absence, former top prospect Gavin Stone is worth streaming in all leagues with a respectable 3.27 ERA, 1.27 WHIP, and 29 punchouts with four wins through 44 innings (eight starts).

Los Angeles Dodgers closer Evan Phillips (hamstring) will need to make either two or three appearances during a minor-league rehab assignment before being activated from the injured list. There was some optimism that Phillips could rejoin LA's bullpen sometime this weekend, but he won't be ready to return from a strained right hamstring for about another week in all likelihood. In 14 appearances before hitting the shelf, the 29-year-old right-hander allowed a lone run while striking out 17, walking four, and converting each of his eight save chances over 13 2/3 innings of work as the Dodgers' closer. Veteran Daniel Hudson remains the best bet for fantasy managers trying to find some saves in Phillips' absence, registering a 2.84 ERA, 0.79 WHIP, and a sublime 20:1 K:BB with two saves over 19 innings, but he hasn't had very many save opportunities.

Tampa Bay Rays starting pitcher Ryan Pepiot (lower leg) is expected to be reinstated from the injured list to start Wednesday's series finale against the visiting Boston Red Sox. After throwing three simulated innings in a bullpen session ahead of Friday's series opener against the division-rival Toronto Blue Jays, Pepiot won't need a minor-league rehab assignment and is ready to rejoin Tampa Bay's injury-riddled rotation following his recovery from a lower left leg contusion. In seven starts this season, the 26-year-old upstart right-hander owns an outstanding 3.68 ERA, 0.93 WHIP, and 41:11 K:BB through 36 2/3 innings as the Rays' ace. However, fantasy managers might want to take a wait-and-see approach before activating Pepiot in a pretty tough spot against Boston's hard-hitting lineup.
