Fantasy managers need to act fast as the June 6, 2026 waiver wire presents a mix of high-upside returns and injury-driven uncertainty. With several key players nearing activation and one starter's status in limbo, your fantasy baseball waiver wire decisions this week could define your roster for the stretch run. Here's a breakdown of the five biggest MLB player news signals shaping your pickups right now.
Jordan Lawlar (ARI) — Return from Injury
Lawlar is eligible to return this week after missing nearly two full months with a broken right wrist suffered on April 3. The Arizona shortstop has been one of the more closely watched names on the fantasy baseball waiver wire, and managers who stashed him should be ready to activate immediately.
The one wrinkle to monitor: Lawlar's return could create an outfield roster crunch in Arizona, with Lourdes Gurriel Jr. also working his way back. How the Diamondbacks manage their roster depth may affect Lawlar's immediate playing time, so watch for official activation and lineup news before finalizing your move.

Chris Bassitt (BAL) — Injury Update
Bassitt exited his Wednesday start after just three innings due to lower-back tightness, leaving his status genuinely uncertain heading into next week. He is tentatively scheduled to make his next start on Monday, but that slot is contingent on a medical evaluation that has not yet been completed.
Lower-back injuries are among the most unpredictable for pitchers, and fantasy managers rostering Bassitt should not count on him for Week 11 lineups until clarity emerges. If you're in a streaming situation, pivot to safer options while monitoring this one closely. Anyone with Bassitt on their bench may want to scan the fantasy baseball waiver wire for emergency SP depth.

A.J. Puk (ARI) — Return from Injury
Left-handed reliever A.J. Puk is making steady progress through his rehab assignment in Reno, having already thrown three scoreless innings in the Arizona Complex League. The Diamondbacks are targeting seven to eight total rehab outings before activating him, putting his return squarely in mid-June.
For deeper mixed leagues and all relief-heavy formats, Puk is worth a speculative add off the fantasy baseball waiver wire now before his activation drives up his ownership percentage. He profiles as a high-leverage arm when healthy, making the timing of his pickup critical for managers who want a head start.
Confidence: 65%
Max Muncy (OAK) — Return from Injury
Muncy has advanced to swing progressions following his fractured hand and is now officially on a rehab assignment at the Triple-A level. This is a meaningful step forward, though his exact return timeline will depend on how he responds over the next several Triple-A appearances.
The third baseman/first baseman's fantasy value is tied entirely to how quickly he can demonstrate he's recovered full grip strength and bat speed. Keep tabs on his rehab stats as they become available. He's a worthwhile watchlist add in most formats, especially in deeper leagues where his position flexibility provides lineup value.
Confidence: 65%
Lourdes Gurriel Jr. (ARI) — Return from Injury
Gurriel became eligible to return Tuesday from his 10-day IL stint due to a left hamstring injury, but the Diamondbacks have indicated he needs additional time to heal before being activated. He is expected to begin a rehab assignment with a mid-June target for full return.
Hamstring injuries carry legitimate re-aggravation risk, and Arizona appears to be taking a measured approach. The added complication is the outfield roster situation created by Lawlar's imminent return. Fantasy managers holding Gurriel should be patient, but those who dropped him may want to check the fantasy baseball waiver wire for availability before his value spikes closer to activation.
