Winckowski will serve as the Red Sox's opening pitcher for Sunday's game against the Yankees, Jen McCaffrey of The Athletic reports.
After making 14 starts for Boston as a rookie in 2022, Winckowski has worked exclusively as a reliever for the Red Sox thus far in his second season in the majors. Though he'll be serving as a starter for the first time in 45 appearances, Winckowski is unlikely to cover more than 1-to-3 innings before turning the game over to Nick Pivetta, whom manager Alex Cora said will work the bulk of the innings in relief. Winckowski enters Sunday's contest with a 3.20 ERA, 1.41 WHIP and 57:18 K:BB in 64.2 innings to go with three wins, two saves and 15 holds.
