2026 Season Highlights

As of July 15, Senga is on the Mets' active roster, appearing as both a starter and a reliever, but he has struggled with his control and is going through a difficult stretch this season. That marks a sharp contrast to last season, when he was a steady presence in the rotation. A proven talent who built his reputation in NPB with his signature 'ghost fork,' he now faces the challenge of turning things around as the season continues.

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.

1In 2026, Senga has split time between starting and relieving, and has struggled with his control during a difficult stretch.
2Known for his signature 'ghost fork,' he built a reputation as one of NPB's premier pitchers before joining the Mets in 2023.
3With experience in both starting and relief roles, how he adjusts and turns things around going forward will be worth watching.

AI · SEASON ANALYSIS

Kodai Senga 2026 Season AI Analysis

Comprehensive 2026 season analysis generated by Claude AI from stats data (as of Jul 20, 2026).

Overview

Senga's 2026 season stands well outside the MLB norm on the traditional run-prevention indicators. His 8.85 ERA is more than double the league average of 3.59 and far outside even the below-average range, while his 1.84 WHIP sits well above the average of 1.19. Across 12 starts and 40.2 innings, the surface numbers place him among the league's most struggling qualified arms in 2026, a sharp departure from the sub-3.50 ERA marks he posted in 2023 and 2025.

Strengths

The swing-and-miss ability has not disappeared. His 10.84 K/9 this season actually exceeds the MLB 90th-percentile threshold of 10.72, meaning his raw stuff still grades as elite by strikeout rate alone. With 49 strikeouts in 40.2 innings, the underlying bat-missing skill is arguably his best of any season, ahead of 2023's 10.93 K/9 across a full year and above 2025's 8.66 mark. This suggests the pitch quality itself remains intact even as results have deteriorated.

Areas to Improve

Command has collapsed. A 6.64 BB/9 is more than double the MLB average of 2.77 and sits far outside the bottom quartile, marking a severe regression from his career norms. This walk rate is the clearest driver of the inflated ERA and WHIP, as free baserunners compound into larger innings. The gap between his elite strikeout rate and his poor walk rate points to a pitcher who can still generate whiffs but cannot consistently locate, a profile very different from his controlled 2023 and 2025 seasons.

Looking Ahead

The data suggests two distinct storylines rather than one uniform decline: strikeout stuff at a 90th-percentile level paired with walk issues at a rate rarely seen among MLB starters. If the underlying arm strength shown in the K/9 number holds, the primary swing factor for the rest of the season is strike-throwing rather than raw pitch quality. Innings volume (40.2 across 12 starts, roughly 3.4 IP per outing) also points to short outings tied directly to pitch counts inflated by walks, making command the single most important variable to track going forward.

PITCHER · FIP

What is Kodai Senga's FIP? 6.89 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 6.89, rated as "below average". That's 2.89 above the MLB average of about 4.00, leaving room to improve.
