The Red Sox continue to make changes to their pitching staff after losing both games of a doubleheader against the Blue Jays at Fenway Park on Monday.
Boston has signed Rich Hill to its active roster from Triple-A Worcester prior to Tuesday’s game against Toronto, the club announced. The club has designated pitcher Brad Keller for assignment to make room for Hill.
The activation marked a return to the major leagues for Hill, who signed a minor league contract with the Red Sox on Aug. 16. The 20-year-old veteran last pitched for Boston in 2022, posting a record of 8-7 in 124 1/3 innings with a 4.27 ERA and 109 strikeouts.
Keller’s recent run with the Red Sox was short-lived after the club activated the right-hander on Monday. Keller pitched four innings against the Blue Jays, allowing five runs (three earned) on seven hits in the fifth inning. He appeared in 11 games for Boston this season, posting a 5.84 ERA over 24 2/3 innings.

The Red Sox also recalled Greg Weissert from the Woo Sox after placing right-handed pitcher Lucas Sims on the 15-day injured list with a right latissimus strain.
Weissert has appeared in 47 games for the Red Sox this season, posting a 2-2 record with a 4.10 ERA in 48 1/3 innings. The right-hander pitched six innings in four games for Worcester and allowed just one run during his time in Triple-A.
Boston has lost five of its last six games and will look to end its losing streak against Toronto after suffering a doubleheader sweep on Monday. First pitch at Fenway Park is scheduled for 7:10 p.m. ET.
