The Toronto Blue Jays, whose recent hot streak has them holding the second American League wild-card position entering Tuesday's games, activated first baseman/designated hitter Brandon Belt from the 10-day injured list among several roster moves.
Belt, who suffered back spasms and was placed on the IL Sept. 12, has slashed .251/.369/.470 with 16 home runs in 97 games this season. His presence is expected to help the Blue Jays' offense as they begin the final six-game stretch of the regular season.
Belt, 35, has not eclipsed 97 games played since 2019, when he played in 156 games for the San Francisco Giants.
Jackson is 3-1 with a 2.36 ERA in 23 games for Toronto this season, tossing 25 strikeouts in 26 2/3 innings of relief.
Pearson won five of seven decisions this season, putting up a 4.85 ERA over 35 relief appearances.
Horwitz was hitting .256 with a home run and seven RBIs through 15 games.
