The Boston Red Sox and pitcher Garrett Whitlock put the pen the paper on a four-year, $18.75 million extension Sunday afternoon, the team announced.
The deal, which could be worth nearly $45 million over six seasons with a pair of club options, will keep the 25-year-old in Boston through at least 2026.
Swiped from the New York Yankees as a Rule 5 draft pick, Whitlock downright dominated in his first season with the Red Sox, with 8-4 record, 1.96 ERA, and 81 strikeouts in 73.1 innings of work over 46 appearances. Whitlock also finished with 15 holds in 2021, which was fourth-most among Boston relievers and tied for the 44th-most in baseball.
The 6-foot-5 righty also appeared in five games during Boston’s 2021 postseason run, with five strikeouts, a 2.16 ERA, and with batters hitting .143 against him over 8.1 innings of work in all.
Whitlock, originally an 18th-round pick of the Yankees back in 2017, pitched 2.1 innings, struck out four, and allowed a home run on Opening Day.
