The fantasy baseball waiver wire is buzzing heading into the July 4th holiday weekend, with a mix of injury setbacks and promising returns shaping roster decisions across leagues. As of July 3, 2026, fantasy managers need to act quickly on several high-priority signals — from a veteran starter's delayed comeback to a hard-throwing ace making his long-awaited return to the mound. Here is everything you need to know to stay ahead on the waiver wire and in your lineup.

Chris Bassitt (BAL) — Injury Update

Chris Bassitt's road back from the injured list just got significantly longer. The 37-year-old Baltimore starter, who was placed on the 15-Day IL on June 8 with low back discomfort, has now undergone a minor back procedure that will delay his return to the major-league mound indefinitely. GM Mike Elias indicated the team will reassess in a couple of weeks before charting a path forward.

For fantasy managers, Bassitt should be dropped in most standard leagues or stashed only in deep formats where roster spots are plentiful. Before the injury, his sinker — used on 41% of pitches — was generating a .362 wOBA allowed compared to a league average of .376, suggesting he was pitching effectively. That context makes the timing of this setback particularly frustrating, but there is no timetable to trust right now.

In line with his recent form

Hunter Greene (CIN) — Return from Injury

The most exciting name on the fantasy baseball waiver wire this week is Hunter Greene, who is cleared and expected to make his return start on July 4th after recovering from elbow surgery. His rehab numbers have been outstanding — a 13:2 strikeout-to-walk ratio across 14.1 innings — signaling that his electric stuff is very much intact. The Reds are reportedly comfortable letting him handle a full workload on Saturday.

Greene is a must-add in virtually every format where he is available. His premium velocity and strikeout upside made him a highly sought fantasy asset before the injury, and a clean rehab line suggests he is not coming back tentatively. Prioritize him at the top of your fantasy baseball pickups list this week — do not wait to see how the first outing goes if you have a roster spot available.

Early signal (high severity)

Trevor Story (BOS) — Return from Injury

Trevor Story is making steady progress in his recovery from sports hernia surgery and is eligible for activation the day after the All-Star break. For fantasy managers in deeper leagues or dynasty formats, this is a return worth tracking closely as a potential mid-season boost at a thin position.

The caveat here is that Story's 2024 season-long splits paint a mixed picture. He posted a strong .794 OPS against right-handed pitching across 86 plate appearances, but struggled considerably against lefties with a .472 OPS in just 20 PA. That platoon vulnerability is worth keeping in mind when projecting his fantasy value post-return, particularly in points leagues where at-bat quality matters.

Early signal (high severity)

AJ Smith-Shawver (ATL) — Return from Injury

Atlanta's AJ Smith-Shawver is working his way back from Tommy John surgery and just completed his second rehab start, allowing only one run and continuing to show encouraging signs of progress. The organization is expected to move him up to a higher affiliate in the farm system soon, which would mark the next meaningful milestone on his path back to the majors.

Smith-Shawver is a name worth keeping on your radar in dynasty leagues and deep keeper formats. He is not a mainstream fantasy baseball pickup yet, but managers in those formats should be monitoring his rehab trajectory closely. There is real upside here if he can string together clean outings at the next level.

Early signal (medium severity)

James McCann (NYM) — Return from Injury

Mets catcher James McCann has begun a rehab assignment as he works back from a right quad strain and is targeting a return to the active roster within the next week. In a position group that is always thin on the fantasy baseball waiver wire, even a streaming-caliber catcher returning from injury is worth monitoring.

McCann's 2024 splits show a relatively consistent bat regardless of pitcher handedness — a .683 OPS vs. right-handers across 149 PA and .638 vs. left-handers across 84 PA. He is not a difference-maker, but in two-catcher leagues or emergency situations, tracking his Triple-A performance before pulling the trigger on an add is the prudent move.
