Fantasy managers need to stay sharp heading into the week of June 11, 2026, as a wave of injury updates is reshaping the fantasy baseball waiver wire landscape. From a high-profile closer nearing a comeback to a rotation stalwart landing on the IL, there's plenty of actionable MLB player news to digest before your next lineup decision. Here's a breakdown of the five biggest signals you need to know right now.
Chris Bassitt (BAL) — Injury Update
Bassitt was pulled from his last start Thursday against the Red Sox due to lower-back tightness and was held back in Baltimore for further examination. The initial concern was significant given his role as a rotation anchor, but early reports suggest he will not miss a start barring any setbacks.
Despite landing on the 15-Day IL, the outlook is cautiously optimistic for the veteran right-hander. Fantasy managers rostering Bassitt should monitor his progression closely before making any waiver wire moves. If you're thin in the rotation and waiting on his return, this is a manageable short-term hold.

Ryan Helsley (BAL) — Return from Injury
Helsley cleared live batting practice and is expected to make his return to game action soon. The closer has been sidelined since early May, and while his return is imminent, he will need multiple tune-up outings before being trusted in save situations again.
This is one of the most important fantasy baseball waiver wire situations of the week. If Helsley's closer role was held by a handcuff on your roster, expect a transition period before he reclaims high-leverage work. In deeper leagues, stash him now before he's fully activated — the demand will spike fast.
Confidence: 85%
Lourdes Gurriel Jr. (ARI) — Return from Injury
Gurriel has been sidelined for three weeks with a left hamstring strain but took a significant step forward by playing seven innings in a rehab game. He is expected to return from the 10-Day IL in mid-June, pending continued rehab progression.
The hamstring history introduces real risk here, and a 65% confidence rating reflects that uncertainty. Fantasy managers in need of outfield help should keep Gurriel on their radar for fantasy baseball pickups, but hold off on a roster move until he's officially activated and shows no lingering issues in game action.
Confidence: 65%
Carlos Santana (ARI) — Return from Injury
Santana posted an encouraging rehab line — 2-for-3 with a home run and two RBI in five innings at first base — and has been taking batting practice at Chase Field. His bat appears ready, but his return timeline remains uncertain due to a crowded situation at first base and DH, with Smith, Vargas, Groover, and the pending returns of Gurriel and Lawlar all competing for at-bats.
This is a tough fantasy baseball waiver wire call. Santana's power upside is appealing, but the roster crunch in Arizona could severely limit his playing time upon return. Check your league's depth before rostering him — he's a speculative add at best in standard formats right now.
Confidence: 65%
Ronald Acuña Jr. (ATL) — Injury Update
Acuña is dealing with a left hamstring strain and is listed as day-to-day. The good news from the latest MLB injury report is that this strain appears less severe than the hamstring issue that kept him out earlier in May. Eli White is slated as the backup option if Acuña misses one to two games.
For fantasy managers, the key here is patience. Don't panic-drop one of the game's most valuable assets over a short absence — especially with the severity downgraded. Keep an eye on the fantasy baseball waiver wire in case White gets spot starts, but Acuña should remain firmly on your roster through this day-to-day designation.
