Brandon Belt was reinstated from the 10-day injured list and will be active for the Toronto Blue Jays' game Wednesday against the Miami Marlins.
The 35-year-old infielder/designated hitter missed time with left hamstring inflammation. He is hitting .263 this season with four home runs and 16 RBI in 152 at-bats.
Spencer Horwitz was optioned to the Blue Jays' Triple-A affiliate in Buffalo, New York, in a corresponding move.
Horwitz had two hits, scored a run and had an RBI in eight at-bats in his three games with Toronto this season.
