Philadelphia Phillies No. 1 prospect Aidan Miller (back) has resumed baseball activities and is expected to begin swinging a bat this week as he recovers from a lower back injury. Miller, the 27th overall pick in the 2023 draft, has yet to make his major league debut but remains one of the organization's top long-term pieces. The young shortstop owns an .817 OPS across his minor league career and has flashed advanced offensive upside. His recovery has moved slowly with limited updates, but Philadelphia will prioritize a full return. There is no official timetable for Miller's next game action.

Atlanta Braves catcher Sean Murphy (hip) will start for Triple-A Gwinnett on Tuesday as he continues his rehab assignment for a right hip labral tear. Murphy previously appeared for High-A Rome and is moving closer to a return in the coming weeks if he avoids setbacks. The veteran opened the season on the 10-day injured list and is expected to reclaim regular catching duties once activated. This is Murphy's third season with Atlanta after arriving in a trade from the Athletics. His production dipped last year, as he slashed .199/.300/.409 with a .709 OPS in 94 games. However, a healthy return would give the Braves a needed boost behind the plate.

Boston Red Sox left-hander Patrick Sandoval (biceps) experienced discomfort after struggling in his second rehab start for Triple-A Worcester on Tuesday, creating another delay in his recovery. Sandoval was scheduled to pitch Sunday, but that outing has been postponed as he returns to Boston for further evaluation. The left-hander has been on the 15-day injured list retroactive to March 22 and has yet to make his debut with the Red Sox. With this new setback, he is expected to return no sooner than May, but that timeline may vary as he receives a full evaluation. Sandoval has not appeared in a major league game since 2024 after missing all of 2025 with an elbow injury. He owns a 4.01 career ERA across six seasons with the Los Angeles Angels.

Athletics outfielder Brent Rooker (oblique) has resumed light baseball activity as he works back from a right oblique strain and is expected to travel with the club for its upcoming road trip to Seattle on Monday. Rooker has been sidelined since April and is targeting a late May return if his recovery continues on schedule. The 31-year-old slugger opened the season slowly, slashing .146/.245/.293 in 12 games before landing on the injured list. Rooker remains one of the Athletics' most important power threats after producing 30 or more home runs in each of the last three seasons. His return should provide a needed boost to the top of the lineup.
