Senga tosses a scoreless inning, extending his recent stretch of short, sharp outings

Kodai Senga turned in another clean outing against the Giants, working one inning with zero hits, zero runs allowed, and one strikeout. That continues a run of short relief outings that has held since early September, so today's line reads less like a one-off good day and more like a continuation of a real trend. Still, the season totals remain difficult — a 7.11 ERA, a 1.60 WHIP, and an 0-9 record across 26 appearances — so a single scoreless inning doesn't change the broader picture just yet.

The underlying numbers support the recent stability. Across his last ten appearances, Senga has combined for 9.1 innings, allowing just 2 earned runs while striking out 9 — a pace that clearly outperforms his season averages in both run prevention and strikeout rate. Outside of the 0.1-inning, 1-run outing on August 24, nearly every recent appearance has been scoreless, and four of the last five outings have gone entirely unscored upon. Limiting his workload to roughly one inning per outing appears to be helping him hold both stuff and command together, rather than fading as pitches accumulate. The platoon split, though, tells a more complicated story: right-handed hitters are batting just .208 with a .793 OPS against him this season, while left-handed hitters are hitting .276 with an .877 OPS and have taken him deep 7 times, compared to 6 home runs allowed to righties. That gap points clearly to left-handed hitters as his lingering weak point, even during this stretch of clean, short outings.

Unico's take: the tighter workload is clearly steadying the surface numbers, but closing the platoon gap against lefties will likely decide whether this recent stretch turns into something more than a short relief specialty.
