Manager Alex Cora said Saturday that Casas (knee) will begin a swinging progression Monday, Christopher Smith of MassLive.com reports.

Cora added that Casas' intercostal strain isn't as significant as the team initially believed, so it shouldn't have too much of an impact on his return timeline while he recovers from patellar tendon surgery. The Red Sox haven't moved him to the 60-day injured list yet, so the door remains open for Casas to return sometime before late May.

The Tigers recalled Montero from Triple-A Toledo on Saturday, Jason Beck of MLB.com reports.

The 25-year-old righty will join the big-league rotation as a replacement for Justin Verlander, who landed on the injured list Saturday with a hip injury. Montero made 20 appearances (12 starts) with the Tigers last season, posting a 4.37 ERA and 1.39 WHIP over 90.2 innings. He began the 2026 campaign by throwing four shutout frames in Triple-A while allowing just one hit and one walk. He'll make his MLB season debut Sunday against the Cardinals.

The Tigers placed Verlander on the 15-day injured list Saturday with left hip inflammation, retroactive to Wednesday, Jason Beck of MLB.com reports.

Verlander was lit up for five earned runs in just 3.2 innings during his first start of the season, and he seems to have come away from his outing with a hip injury. He'll be eligible to return April 16, though it's unknown if he'll be ready by then. In the meantime, Keider Montero will come up from Triple-A Toledo to fill the opening in Detroit's rotation.

Merrill isn't in the lineup for Saturday's game against the Red Sox.

Merrill doesn't typically step out of the lineup against left-handed starters, but after a 5-for-27 (.185) start to the season, he'll sit on the bench, with Connelly Early on the mound for Boston. Bryce Johnson will pick up a start in center field as a result and bat ninth.

Hernandez isn't in the lineup for Saturday's game against the Nationals.

Hernandez will get a chance to catch his breath Saturday after going 3-for-4 with an RBI and three runs scored during a blowout victory in Friday's series opener. Alex Call will fill the void in left field and bat ninth.

The Twins transferred Festa (shoulder) to the 60-day injured list Saturday, Aaron Gleeman of The Athletic reports.

Festa was shut down early in spring training due to a shoulder impingement and still has yet to begin throwing off a mound. His move to the 60-day IL will ensure he remains sidelined until at least late May and opens up a spot on the 40-man roster for Garrett Acton, whom the Twins acquired Thursday in a trade with Miami.

Wiemer isn't in the lineup for Saturday's game against the Dodgers, Mark Zuckerman of NatsJournal.com reports.

Despite opening the season white-hot at the plate, Wiemer will retreat to the bench for a second consecutive game while Daylen Lile, Jacob Young and James Wood start across the outfield for Washington.

Nunez isn't in the lineup for Saturday's game against the Dodgers, Mark Zuckerman of NatsJournal.com reports.

Nunez will get a breather after going 1-for-5 and scoring a run during Friday's blowout loss. Jorbit Vivas will fill in as Washington's second baseman and bat seventh.

Ruiz isn't in the lineup for Saturday's game against the Dodgers, Mark Zuckerman of NatsJournal.com reports.

The Nationals appear to be content alternating between Ruiz and Drew Millas behind the dish, and Saturday marks the latter's turn to join the starting nine.

Bernardino will serve as the Rockies' opening pitcher Saturday against the Phillies.

The Phillies typically use lefty sluggers Kyle Schwarber and Bryce Harper atop their lineup, so the Rockies will counter by sending the left-handed Bernardino to the mound for the first inning. The 34-year-old has fired three scoreless innings to begin the season, giving up two hits, no walks and striking out one batter in the process. Chase Dollander is expected to pitch in bulk relief once Bernardino exits the game.
