The Red Sox promoted Zack Kelly and Kaleb Ort to join their bullpen on Sunday, per multiple reports.
To make room, the team reportedly designated Hirokazu Sawamura and Austin Davis for assignment.
Kelly will make his major-league debut after striking out 72 batters while walking 25 in 49.2 innings pitched this season with the WooSox. The 27-year-old signed with the A’s as an undrafted free agent in 2017, netting just $500 for his signing bonus. In 2020, he tore the UCL in his pitching arm but avoided Tommy John surgery and climbed through the Red Sox’s minor leagues with a fastball and changeup that Sox Prospects graded “potential plus” and “potential above average” offerings.
