Kodai Senga might be the biggest question mark in terms of potential 2026 outcome out of every player on the New York Mets’ roster.

On one hand, it seems like the Mets getting an elite pitcher in Senga this season is a real possibility. He was a true ace in 2023, as shown by his 12-7 record, 2.98 ERA, and 202 strikeouts in 166.2 innings pitched. Given that this was his rookie campaign, Mets fans believed they had found their ace for the future with the Japanese standout.

Then came the next two seasons. 2024 was essentially lost for Senga, given that he only made one regular season start because of various injuries. Then 2025 came around, and Senga got off to a hot start before essentially collapsing in the second half of the season. While he finished 2025 with a respectable 3.02 ERA, he couldn’t pitch late into games and struggled immensely when it mattered most, to the point where New York actually demoted him to the minor leagues for the final month.
