Sonny Gray threw seven shutout innings in Pittsburgh on Saturday and improved to 15-3 with a 2.65 ERA in his first season with the Boston Red Sox. The win total alone is a career best, but the context around it is what makes it something more: Gray reached 15 wins in just 23 starts — the same pace at which Pedro Martínez did it in 1998, the only time in the last 28 years a Red Sox pitcher hit that mark that fast.
The Night at PNC Park
The August 15 game against the Pittsburgh Pirates didn’t need much offense. A solo home run by Wilyer Abreu in the second inning was all Boston had until the ninth, when Andruw Monasterio doubled with two runners on and Jahmai Jones drove in another to close out a 4-0 final. Gray didn’t need more support than that.
He allowed 6 hits, 1 walk and struck out 7 on 86 pitches before handing it over to the bullpen, which finished off the combined shutout. It was Gray’s fifth start of at least seven innings this season and the 13th time in his last 14 outings that he’s gone at least six. That kind of week-in, week-out consistency — not the occasional brilliant outing, but the floor never dropping — is exactly what’s gotten him here.
The win also came at a rough moment for the team: it was just Boston’s second victory in their last eight games and snapped a five-game losing streak. The fact that Gray was the one to stop the bleeding says a lot about what he means to this club in August.
The Number That Puts It All in Perspective: Pedro Martínez, 1998
According to ESPN Insights, Gray is the fastest Red Sox pitcher to reach 15 wins in a season since Pedro Martínez in 1998 — also in 23 starts. That was Pedro’s first year in Boston after being traded from the Expos; he finished 19-7 with a 2.89 ERA, then went on to win the Cy Young the following year in one of the most studied pitching seasons in baseball history.
Matching that pace — even as a threshold rather than a destination — gives Gray’s 2026 campaign a different kind of weight.
He’s also the third Red Sox starter since 2019 to reach 15 wins or more in a season, joining Eduardo Rodríguez (19 in 2019) and Garrett Crochet (18 in 2025). He’s the first American League pitcher to hit 15 wins in 2026, tied at the top of the majors with Cristopher Sánchez.
One more detail worth noting: Gray made his MLB debut on July 10, 2013, at PNC Park with Oakland. Thirteen years later, at that same ballpark, he picked up career win No. 15 with his new team. Baseball does that sometimes.
How Gray Dominates at 36
Sonny Gray’s fastball averages 90.7 mph — 14th percentile in MLB, among the slowest in the league. But his spin rate of 2,477 rpm (81st percentile) makes it behave differently than hitters expect. The result: 22.7% of swings against him miss entirely, and he generates out-of-zone swings at the 78th-percentile rate. He doesn’t beat you with velocity. He beats you with movement and deception.
His control is his quietest weapon: just 34 walks in 132.2 innings (82nd percentile in BB%), against 117 strikeouts. Statcast shows opposing hitters making contact at an average exit velocity of just 89 mph — soft contact — with a barrel rate of only 6.1%. His xERA of 3.6 suggests some good fortune has gone his way, but a 2.65 ERA and 1.15 WHIP over 23 starts isn’t luck.
