Pirates Infielder Making MLB Debut vs. Red Sox

The Pirates, themselves, look to get a sweep over the Red Sox, as they won 4-2 in the series opener on Aug. 29 and 10-3 on Aug. 30. They swept the Red Sox at Fenway Park, April 3-5, 2023, and could make it six straight wins at the oldest ballpark in the MLB.

Bryan Reynolds is not in the starting lineup for the Pirates, as Alexander Canario takes over in right field and bats eighth. This is his first time not featuring in the Pirates' lineup since the series opener vs. the San Francisco Giants at PNC Park on Aug. 4.

This is the 11th time that Canario has started in right field and the first time since the series opener vs. the Giants at Oracle Park on July 28.

Henry Davis comes in at catcher for the Pirates, taking over from Joey Bart, and will bat seventh, marking the last change in the lineup.

Jared Triolo and Spencer Horwitz remain at shortstop and first base, plus first and second in the Pirates lineup, respectively. Nick Gonzales continues on at second base, but moves up two spots to fourth in the batting order.

Tommy Pham stays in left field, but moves up one spot to third in the lineup, while Oneil Cruz continues on in center field, but moves up one spot to sixth in the batting order, completing the Pirates' outfield.

Andrew McCutchen remains at designated hitter and bats fifth for the Pirates, finishing out the lineup.

Right-handed pitcher Mitch Keller will close it out for the Pirates in the series finale vs. the Red Sox.

Keller threw six innings vs. the Cardinals on Aug. 26 in his last start, giving up three hits, two hit batters, one walk, three earned runs and one home run, while posting a season-high nine strikeouts in the 8-3 win.

It marked the 16th quality start in 2025 for Keller, tied for the 10th most in the MLB, and matched his most strikeouts in a game since he also had nine strikeouts vs. the Texas Rangers at Globe Life Field on Aug. 20, 2024.

Keller hasn't had the greatest outings in August, with a 2-2 record in five starts, a 7.88 ERA over 24.0 innings pitched, 25 strikeouts to 10 walks, a .316 opposing batting average and a 1.71 WHIP.

He has a 6-12 record over 27 starts in 2025, a 4.35 ERA over 151.0 innings pitched, 125 strikeouts to 43 walks, a .255 opposing batting average and a 1.28 WHIP.

First pitch is set for 1:35 p.m.
