Paul Skenes takes the mound at PNC Park on Tuesday night to open a pivotal six-game homestand, and he’s carrying momentum for the first time in weeks. The reigning NL Cy Young winner closed out August with his best outing since mid-May, and now he squares off against the San Francisco Giants and fellow All-Star Logan Webb with Pittsburgh clinging to the edge of the playoff race.

Skenes enters the night 9-11 with a 3.79 ERA, 175 strikeouts and a 1.12 WHIP across 145 innings, numbers that still rank among the National League’s better marks but represent a real step back from the historic peak that won him the Cy Young last season. He hasn’t picked up a win since July 19, an odd footnote given how well the Pirates have played behind him lately, having won each of his last two starts. His most recent turn was his sharpest of the summer: six shutout innings on the road in San Diego, his first scoreless outing since May 12, snapping a stretch in which he’d posted a 4.40 ERA over his previous eight starts.

A Cy Young Defense Built on Late-Season Surges

The gap between this year’s Skenes and the pitcher who authored a 1.96 ERA as a rookie in 2024 and a 1.97 ERA last season is stark. His ERA has climbed by more than a full run, his FIP has followed a similar trend, and his Statcast expected-stats percentile has slipped from the 100th percentile the last two years down to the 95th in 2026 — still elite, but no longer untouchable. Barrel rate against him has ticked up, and hitters are squaring him up on the road in particular, where his ERA sits closer to 4.00 compared to a much tighter number at PNC Park. It’s the first time in his three-year career that Skenes has looked genuinely mortal for extended stretches, and it has coincided with Pittsburgh becoming the first team to have a reigning Cy Young winner post a record at or below .500.

None of that erases what Skenes still is: a strikeout artist averaging nearly 11 punchouts per nine innings with a 30 percent strikeout rate that places him among the sport’s most dominant arms when he’s locating his stuff. Bettors still installed him as a solid favorite for Tuesday’s series opener, and anyone tracking the number will find it alongside the rest of the day’s MLB odds as first pitch approaches at PNC Park.

Homestand Stakes and a Rare Giants Rematch

Tuesday marks just the second time in Skenes’ career that he’s faced San Francisco. The first came in the third start of his career back in May 2024, when he held the Giants to one run over six innings before Pittsburgh’s bullpen blew a 5-1 lead in a 7-6 loss. This time, the stakes are considerably higher. The Pirates open their homestand at 67-71, four games under .500, and need to win five of their six games against the Giants and the Los Angeles Angels just to climb back to break-even as September begins. A decade without a postseason appearance hangs over the organization, and Skenes is scheduled to pitch twice during this stretch, giving Pittsburgh two chances to lean on its ace when it matters most.

Webb, for his part, brings a strong season of his own to the mound — 8-8 with a 3.72 ERA and 118 strikeouts — setting up a genuine pitchers’ duel between two of the National League’s more respected arms.

What happens over these next two weeks could shape how Skenes’ age-24 season is remembered. A strong finish, punctuated by more outings like his shutout effort in San Diego, would validate that his midseason stumble was a blip rather than a trend, and it would go a long way toward getting the Pirates back into relevance in the NL Central race. A shaky finish, on the other hand, would only reinforce how far Skenes has fallen from the near-flawless standard he set as a rookie and sophomore. Either way, PNC Park will be watching closely as its ace tries to author a September turnaround for both himself and his team.
