As of June 2, 2026, fantasy managers need to act fast on a wave of MLB injury report developments shaping the fantasy baseball waiver wire landscape. From a star closer trending toward a June return to a veteran ace still weeks away from activation, the latest signals demand immediate roster attention. Here's everything you need to know to make the right pickups before your leaguemates do.
Corbin Burnes (ARI) — Return From Injury
Burnes is advancing through his rehab program and has progressed to live batting practice sessions, a meaningful step in his recovery process. However, his expected return is targeted for after the All-Star break, meaning fantasy managers should plan for a significant absence over the next several weeks.
In dynasty and keeper formats, Burnes remains a must-hold asset, but in redraft leagues he's a roster crunch problem. If you're thin on bench space, this is a tough hold while better options may be available on the fantasy baseball waiver wire.

Pavin Smith (ARI) — Return From Injury
Smith has begun a rehab assignment following elbow surgery, and the Diamondbacks are pursuing an accelerated return timeline. Once activated, he is projected to compete for starts at both first base and designated hitter, particularly against right-handed pitching.
Smith carries multi-position eligibility value and is worth a speculative pickup in deeper leagues right now. His ceiling depends on how quickly he reclaims regular at-bats, so monitor his rehab assignment closely before spending significant waiver priority.
Confidence: 85%
Ryan Helsley (BAL) — Return From Injury
Helsley is trending toward a June return from the 15-Day IL and is expected to reclaim his role as the Orioles' closer once he's healthy and activated. This is one of the most actionable signals on the fantasy baseball waiver wire right now given the premium value of saves.
If Helsley is sitting on your waiver wire, pick him up immediately. Closers with a defined role and a near-term return are rare commodities, and his rehab assignment progress should be monitored daily for activation timing. Don't let a leaguemate sneak him off the wire ahead of you.
Confidence: 85%
Max Muncy (OAK) — Return From Injury
Muncy is working his way back from a fractured left hand and has started a Triple-A rehab assignment with Oakland's affiliate. His return timeline will sharpen as he accumulates minor-league at-bats and the organization assesses his readiness to resume full game action.
For fantasy managers, Muncy is a speculative add in deeper leagues who offers positional flexibility and power upside if he returns healthy. However, with a moderate confidence signal and no firm activation date yet, avoid spending high waiver priority on him. Keep him on your watchlist and check back as MLB player news develops.
Confidence: 65%
Carlos Santana (ARI) — Role Reduction
The 40-year-old first baseman was Arizona's primary starter at the position before hitting the 60-day IL, but Ildemaro Vargas has stepped in and emerged as a legitimate replacement during Santana's absence. When Santana is activated, his role is expected to be limited rather than automatic.
This is a clear drop candidate in most standard fantasy formats. If you've been holding Santana hoping for a full-time return, the emergence of Vargas changes the calculus significantly. Managers in daily lineup leagues should explore the fantasy baseball waiver wire for better first base options immediately rather than waiting on a reduced-role return.
