MLB Injury Report — September 5, 2026

Here are today’s most important MLB injury and player-availability updates, with an emphasis on news that could affect lineups, bullpens, sides, totals and player props.

𝐋𝐨𝐬 𝐀𝐧𝐠𝐞𝐥𝐞𝐬 𝐃𝐨𝐝𝐠𝐞𝐫𝐬 — Shohei Ohtani

Ohtani is dealing with injuries involving his right biceps, left knee and neck. He has missed two consecutive games and is considered day-to-day, with another absence possible tonight against Washington. The Dodgers have not seriously considered placing him on the injured list.

BETTING IMPACT: Ohtani’s availability is the most important pending lineup decision of the day. His absence affects Los Angeles’ projected run production, team total, first-five market and multiple player-prop markets. Bettors should wait for the official Dodgers lineup before finalizing any offensive evaluation.

𝐍𝐞𝐰 𝐘𝐨𝐫𝐤 𝐘𝐚𝐧𝐤𝐞𝐞𝐬 — Trent Grisham

Grisham left Friday’s game against San Diego with a right hamstring injury and is expected to undergo imaging. He aggravated the hamstring while attempting to steal second base and later struggled while pursuing a ball in the outfield. It is the same hamstring that previously forced him onto the injured list, although the discomfort is reportedly in a different area.

BETTING IMPACT: Grisham is unlikely to be available at full strength and could be held out entirely. Spencer Jones is the leading candidate to move into center field, with Heliot Ramos potentially entering the outfield alignment. The change affects New York’s defense, lineup depth and player-prop opportunities.

𝐒𝐞𝐚𝐭𝐭𝐥𝐞 𝐌𝐚𝐫𝐢𝐧𝐞𝐫𝐬 — Lazaro Montes

Montes exited Friday’s game after crashing into the right-field wall and suffering left-hip soreness. X-rays were negative, which is encouraging, but he was visibly uncomfortable and is expected to be reevaluated today.

BETTING IMPACT: Montes should be considered questionable for tonight’s game against the Athletics. Seattle could use Taylor Ward in the outfield or make an additional roster move if Montes requires time off. His status affects the bottom and middle portions of the Mariners’ lineup, depending on the final batting order.

𝐇𝐨𝐮𝐬𝐭𝐨𝐧 𝐀𝐬𝐭𝐫𝐨𝐬 — Steven Okert

Houston placed Okert on the 15-day injured list with a right hamstring strain, retroactive to September 1. Okert has been one of the Astros’ most dependable relievers, recording a 2.13 ERA across a team-leading 68 appearances. Bryan King was recalled to replace him.

BETTING IMPACT: This is a meaningful bullpen loss. AJ Blubaugh, Bennett Sousa and other Houston relievers could receive higher-leverage assignments. Okert’s absence matters most when evaluating Houston’s full-game moneyline and late-inning bullpen advantage.

𝐓𝐚𝐦𝐩𝐚 𝐁𝐚𝐲 𝐑𝐚𝐲𝐬 — Bryan Baker

Baker left Friday’s appearance with a trainer after walking two batters, but the early indication is that he was removed because of illness rather than a physical injury. He is presently considered probable for today.

BETTING IMPACT: This is not considered a significant injury concern unless Tampa Bay provides a downgrade. His availability still matters because he has handled important late-inning work. Tyler Wells could receive another save opportunity if Baker is unavailable.

𝐊𝐚𝐧𝐬𝐚𝐬 𝐂𝐢𝐭𝐲 𝐑𝐨𝐲𝐚𝐥𝐬 — Maikel Garcia

Garcia is progressing in his rehabilitation from a left hamstring strain. He is running at approximately 80% and participating in baseball activities, but he remains on the injured list and will not be available for tonight’s game against Toronto.

BETTING IMPACT: This is a positive long-term update but does not change today’s lineup. Kansas City remains without one of its more productive and versatile position players.

𝐀𝐫𝐢𝐳𝐨𝐧𝐚 𝐃𝐢𝐚𝐦𝐨𝐧𝐝𝐛𝐚𝐜𝐤𝐬 — Zac Gallen

Gallen threw 60 pitches across four innings in a simulated game Friday as he continues recovering from an elbow injury. Arizona is targeting activation during its upcoming series against Kansas City, with a possible start Wednesday.

BETTING IMPACT: Gallen will not affect tonight’s game against Houston, but his expected return could materially strengthen Arizona’s rotation next week. Bettors should monitor whether the Diamondbacks confirm Wednesday as his return date.

SUMMARY

The biggest pending lineup decisions involve Shohei Ohtani, Trent Grisham and Lazaro Montes. Ohtani’s status carries the greatest potential impact on tonight’s betting market.

Steven Okert’s move to the injured list is the most significant confirmed pitching development because it weakens Houston’s late-inning bullpen structure. Bryan Baker’s exit currently appears illness-related and should not be treated as a significant injury unless Tampa Bay announces a setback.

Final starting lineups and late scratches should be checked before first pitch, particularly for the Yankees, Dodgers and Mariners.
