2026 Season Highlights

As of 10/1, Kodai Senga is on the Mets' active roster, having worked as both a starter and a reliever this season. His results have dropped noticeably from last year, with losses piling up and his run prevention and baserunner numbers struggling. He has still missed plenty of bats and even picked up saves in a late-inning role. That marks a sharp change from last season, when he was a steady presence in the rotation.

Kodai Senga's signature "Ghost Fork" — a devastating forkball with sharp downward break — makes him one of the most dangerous strikeout pitchers in baseball. After injuries and a minor league demotion derailed his 2024 and 2025 seasons with the Mets, Senga has bounced back in 2026. He returned to the rotation from Opening Day and has been pitching like the ace the Mets envisioned when they signed him in 2023.

1This season he has moved between starting and relief roles, and his results have fallen well short of last year's steadiness. Wins have been hard to come by, and runs and baserunners have been frequent problems.
2His signature weapon is the "ghost fork," and his ability to generate swings and misses remains intact this year. A former NPB wins leader who joined the Mets in 2023, he has kept his strikeout-getting identity.
3Watch how well he can limit walks and home runs in whatever role he is given going forward. It will also be worth following whether he can recover the steady form he showed last season.

AI · SEASON ANALYSIS

Kodai Senga 2026 Season AI Analysis

Comprehensive 2026 season analysis generated by Claude AI from stats data (as of Sep 28, 2026).

Overview

Senga's 2026 line sits well below MLB average across the board: 7.34 ERA (vs 3.57 avg) and 1.65 WHIP (vs 1.18 avg) place him near the bottom of qualified starters, far outside the P75 threshold of 3.00 ERA. His K/9 of 11.01 is actually above P90 (11.12 is the P90 mark, so this is right at the elite tier), which is the one number keeping his profile from being a total outlier. The gap between strong strikeout stuff and poor run prevention is the defining tension of this season.

Strengths

The swing-and-miss ability has not gone anywhere and has, if anything, sharpened. K/9 of 11.01 tops his best prior mark (10.93 in 2023) and sits at an elite MLB percentile (P90 territory). Across 61.1 innings he has piled up 75 strikeouts, confirming the forkball-driven whiff profile that made him valuable in 2023 and 2025 is still present in the pitch quality. This suggests the raw stuff is intact; the season's problems are not about diminished swing-and-miss capability.

Areas to Improve

Command has collapsed relative to every prior MLB season. BB/9 of 6.02 is more than double the MLB average of 2.75 and far outside the P50 mark of 2.55 — this is the clearest driver of the ERA and WHIP damage. The 1.65 WHIP reflects both the walks and increased baserunners overall, and the ERA of 7.34 is over twice the league average. Compared to his 2023 (2.98 ERA) and 2025 (3.02 ERA) form, this represents a sharp decline concentrated almost entirely in control rather than stuff.

Looking Ahead

The data points to a command-specific breakdown rather than a decline in raw ability, given the strikeout rate holds at elite levels. If walk rate trends back toward his career norms (career BB/9 sat closer to 3, not 6), the ERA and WHIP should correct significantly given the swing-and-miss foundation remains intact. Until BB/9 shows sustained improvement across upcoming starts, the season's overall results are likely to remain below MLB average regardless of strikeout totals.

PITCHER · FIP

What is Kodai Senga's FIP? 5.82 in 2026

FIP (Fielding Independent Pitching) measures a pitcher's true skill using only home runs, walks, hit-by-pitches and strikeouts — outcomes the pitcher controls. By stripping out defense and luck, it tracks real ability more closely than ERA.

Kodai Senga's 2026 FIP is 5.82, rated as "below average". That's 1.82 above the MLB average of about 4.00, leaving room to improve.
