Becoming the fourth pitcher this season to make his Major League debut with the Red Sox was right-hander Mike Shawaryn, as he did so last night in a 5-1 loss at home to the Tampa Bay Rays.
Shawaryn, a fifth-round pick by Boston in 2016, came on to pitch the eighth and ninth innings. He struck out four and allowed only one base-runner—a Kevin Kiermaier leadoff homer in the ninth.
The 24-year-old was 1-2 in 10 games (all starts) this season for the Paw Sox with a 3.72 ERA. He waited over a week to make his debut, as he was recalled by the team on May 30.
Since 2017, Shawaryn is 18-19 with a 3.63 ERA in 62 games (all but one are starts) within the Red Sox farm system. He also has 346 strikeouts in that time, just more than his 339 1/3 innings.
