Imanaga's latest 2026 stats are updated daily in the stats box at the top of this page. ERA, strikeouts, WHIP, and innings pitched are tracked in real time. Through April 27 he has 38 strikeouts in 34.1 innings (K/9 ~9.96) with a 0.87 WHIP — one of the best strikeout-to-walk profiles among NL starters this season.
Through April 27, Imanaga is 2-2 with a 3.15 ERA, 38 strikeouts, and a 0.87 WHIP across 6 starts (34.1 IP). The 0.87 WHIP ranks among the elite for MLB starters and his K/9 of about 9.96 confirms full restoration of the swing-and-miss form that made him a Rookie of the Year contender in 2024. The Cubs accepted his Qualifying Offer (~$22M) for 2026 and his early-season production is exceeding that contract value.
Imanaga's 2026 ERA sits at 3.15 with a K/9 of approximately 9.96 (38 strikeouts in 34.1 innings) through 6 starts as of April 27. For context, MLB starter average ERA hovers near 4.20 and average K/9 is around 8.5 — Imanaga is comfortably above average in both. His 0.87 WHIP further confirms elite contact suppression and walk prevention.
Imanaga is a left-handed starting pitcher for the Chicago Cubs. He pitches every five days in Chicago's rotation. His sharp slider and elite command of multiple pitch types make him one of the more effective left-handed starters in the National League.
Shota Imanaga was born on May 13, 1993, making him 32 years old during the 2026 MLB season. He joined the Cubs before the 2024 season after establishing himself as one of the top pitchers in NPB with the Yokohama DeNA BayStars.
As a left-handed pitcher, Imanaga has a natural platoon edge against left-handed hitters — his sharp slider dives away from them. However, his 2026 K/9 of about 9.96 (38 K in 34.1 IP) confirms swing-and-miss against batters of both handedness. His elite command and pitch sequencing prevent the pronounced platoon splits that limit many same-side pitchers.

Comprehensive 2026 season analysis generated by Claude AI from stats data.
Through 8 starts and 47.1 innings, Imanaga sits in strong territory across the slash line. His 2.28 ERA clears the MLB P75 mark of 2.63 and approaches the P90 threshold of 2.11, while his 0.93 WHIP is below the P90 benchmark of 0.95. The 10.08 K/9 ranks between P75 (9.77) and P90 (10.73), and his 2.47 BB/9 falls between P50 (2.86) and P75 (2.28). The early sample places him among the more efficient mid-rotation arms league-wide, though innings remain limited at this point of the calendar.
The most notable shift is the strikeout rate. After 9.03 K/9 in 2024 and a regression to 7.28 in 2025, his current 10.08 represents the highest mark of his MLB career and now exceeds league average by more than a strikeout and a half per nine. Walk control remains intact at 2.47 BB/9, keeping the K/BB profile favorable. The 0.93 WHIP also marks a clear improvement from 2025 and indicates better contact management, with baserunners suppressed below the top decile threshold.
Relative to the elite tier, the gap is narrow rather than structural. His K/9 trails the P90 mark by 0.65, suggesting room remains against the strikeout leaders. The 2.47 BB/9, while solid, is slightly above the P75 cutoff of 2.28, meaning command is good but not pinpoint. Workload is also worth monitoring: 47.1 innings across 8 starts averages under 6 frames per outing, which is roughly league norm but not a length-driver. Sustaining the current ERA over a full season would require maintaining suppressed contact quality.
The early profile resembles his 2024 form with a stronger strikeout component, though it remains an 8-start sample. Regression toward his career ERA range (mid-2s to mid-3s) is a reasonable baseline expectation, particularly if BABIP and strand rate normalize. Key indicators to watch are whether the elevated K/9 holds as opposing lineups adjust, and whether innings per start trend upward into the summer. If the strikeout gains prove durable, a sub-3.00 ERA finish is plausible; if not, a figure closer to his 2024 baseline is the likelier landing spot.
