The Boston Red Sox added another pitcher to their major league staff, acquiring Pittsburgh Pirates right-hander Quinn Priester in exchange for minor league infielder Nick Yorke on Monday.

Priester, 23, is 2-6 with a 5.04 ERA over 44 2/3 innings in 10 games (six starts) this season, with 31 strikeouts and 13 walks.

In 20 career games (14 starts), the Pirates’ 2019 first-round pick is 5-9 with a 6.46 ERA spanning 94 2/3 innings, with 67 strikeouts and 40 walks.

Yorke, 22, ranked as the Red Sox’s No. 6 prospect by MLB Pipeline, was their first-round pick in the 2020 draft. In 83 games this season between Double-A Portland and Triple-A Worcester, he hit .278 (89-for-320) with 16 doubles, 10 home runs, 14 stolen bases and 46 RBIs.

“Nick has been a strong offensive performer and versatile defender in the minor leagues,” Pirates general manager Ben Cherington said of Yorke, who will report to Triple-A Indianapolis. “We are excited to add him to our upper-level position player group.”

Prior to trading for Priester, the Red Sox acquired fellow starter James Paxton from the Los Angeles Dodgers last week to bolster their staff.
