Kyle Harrison shined for the Brewers on Sunday.
The pitcher turned in the best outing of his career with a 12-strikeout performance across six shutout innings in Milwaukee ’s 5-0 win over the Pittsburgh Pirates .
Harrison also allowed just one hit.
The 24-year-old became the first Brewers pitcher to toss at least six scoreless innings and amass 12 strikeouts since Freddy Peralta in 2023, and joined Juan Nieves (1986) and Eric Lauer (2022) as the only left-handed pitchers in Brewers history to do so.
Harrison was the key piece acquired by the Red Sox as part of the blockbuster Rafael Devers trade last June. He was expected to be rotation depth going into 2026.
The southpaw threw just 12 innings for Boston .
The Red Sox traded Harrison in February in a deal that included the Brewers sending Caleb Durbin to Boston. A 2025 Rookie of the Year finalist, Durbin is batting .169 with one home run and 10 RBI in 26 games for Boston.
After Sunday’s star Harrison improved to 2-1 with a 2.28 ERA, 1.056 WHIP and 30 strikeouts.
