Mets Activate Mark Vientos from Injured List, Batting Cleanup Against Rays

Vientos Returns to Mets Lineup

The New York Mets began a new series on Monday, August 31, on the road against the AL East-leading Tampa Bay Rays. Before the game, the Mets activated Mark Vientos from the injured list, a decision reported by Heavy. Vientos, who has been out since early July with a fractured right hand, was batting cleanup as the designated hitter in his first game back.

According to RotoWire staff, cited in Heavy's report, Vientos was cleared to return after going 9-for-23 with five home runs in seven rehab games, including a three-homer performance at Triple-A Syracuse on Sunday. The 26-year-old will see action at designated hitter, as reported.

Rehab and Return

NBC Sports reported that Vientos had been sidelined since July 10 with a fractured right hand, just before the All-Star break. His rehab assignment began late last week, and he was expected to rejoin the Mets early the following week. The power he showed during rehab suggests the hand fracture has not diminished his hitting ability.

Season Struggles

Vientos has had a difficult season. Before the injury, he was slashing .211/.256/.388 with 11 home runs and 35 RBI in 254 plate appearances, according to NBC Sports. Heavy reported his OPS+ for the 2026 season is 78, well below average. He has also struggled against right-handed pitching, posting a .169/.215/.297 line in 158 plate appearances against right-handers, as reported by NBC Sports.

Vientos had a breakout 2024 season, hitting 27 home runs in 111 games. However, in 194 games since then, he has totaled 28 home runs and has posted back-to-back below-average OPS+ seasons, as noted by Heavy.

The Mets, who are out of playoff contention, may use the remainder of the season to evaluate Vientos, who has no minor league options left, according to NBC Sports. His playing time in September remains uncertain, as he may need Juan Soto, currently serving as designated hitter after a calf injury, to return to the outfield for Vientos to see regular action, per NBC Sports.

With the Mets facing the Rays, who are in playoff position, Vientos' return could influence the team's spoiler role in the final stretch of the season.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
