Paul Skenes Has an Explanation for 2026. The Pirates' 80-Win Season Doesn't

The most compelling Pirates story of the final week isn't the standings math — it's the autopsy. Paul Skenes, the reigning Cy Young winner, finished his 2026 season with a 3.91 ERA over 31 starts, and he pointed to the World Baseball Classic as a factor in his diminished velocity. It's a reasonable thing for a pitcher to say and an unsatisfying thing for Pittsburgh to hear, because the Pirates are 80-78, out of October, and the man who was supposed to carry them there just had the worst year of his professional life.

The regression, by the numbers

The drop-off from 2025 to 2026 is stark. Skenes went from a 1.97 ERA and 0.95 WHIP across 187.2 innings to a 3.91 ERA and 1.13 WHIP across 168. His earned runs nearly doubled (41 to 73) while he threw roughly 20 fewer innings. He still struck out 192 batters against 47 walks, so this wasn't a collapse — it was a pitcher who stopped being unhittable.

More troubling is the direction of travel. Over his last ten starts, Skenes posted a 4.53 ERA with a 1.26 WHIP and a strikeout rate that sat below his career standard. His quality-start rate for the season settled at 40 percent, and his most recent outing — six innings, five earned runs, seven strikeouts against Kansas City on Sept. 18 — was a fitting closing statement.

There's a fair counterargument: his 3.30 FIP was meaningfully better than his ERA, suggesting some of the damage was sequencing rather than stuff. That's a real distinction, and it matters for how 2027 gets projected.

Why it was fatal for Pittsburgh

The Pirates scored 751 runs and allowed 724 — a plus-27 run differential, a winning record, and no playoff berth. That's the profile of a team that lost the margins. The bullpen is the obvious crime scene: a 4.21 relief ERA, 13 blown saves against just 14 saves, and 28 holds. Those first-half meltdowns were, as the local coverage noted, cumulative.

And Skenes was handed a heavier share of blame than he deserved. ESPN labeled him Pittsburgh's biggest disappointment, pointing to the Pirates' 13-17 record in his 30 starts. But a team that goes 13-17 behind a pitcher with a 3.30 FIP is telling you about its offense and its bullpen, not about its ace. FanDuel had his Cy Young repeat priced at roughly a 2.8 percent implied probability entering the final week — a long shot, but not the profile of a broken pitcher.

The decision that outranks the Skenes question

Brandon Lowe is the louder story for 2027. He hit .262 with 34 home runs, 94 RBI and an .825 OPS in 147 games, earned a Roberto Clemente Award nomination, and is heading into free agency with reported mutual interest in a return. He's also locked in a tight NL Silver Slugger race at second base with Milwaukee's Brice Turang.

The mandate in Pittsburgh was playoffs or bust — team president Travis Williams said so. That mandate failed, GM Ben Cherington may survive it anyway, and the offseason now hinges on whether the Pirates keep the best hitter they've added in a decade. Losing Lowe without a comparable replacement would undercut any claim that 2027 is different.

What the final week shows

Pittsburgh is 6-4 over its last ten and 4-1 over its last five, with a 3.95 ERA in that stretch and an .793 OPS — the kind of late surge that made this season's ending feel less like collapse than waste. The Pirates host St. Louis at PNC Park to close it out, with Skenes' season already in the books.

The Skenes explanation is worth taking at face value. The harder question is what the Pirates do now that a plus-27 run differential bought them nothing, and whether the pitching that carried this roster gets an offense and bullpen worth carrying next year.
