Stamets signed a minor-league contract with Toronto on Friday.
The 30-year-old's only big-league experience came with Cleveland in 2019, when he struggled to a .049/.149/.073 line in 15 games while striking out in half of his plate appearances. He's unlikely to offer the Guardians anything more than organizational depth in the middle infield, as his .569 OPS in 34 Triple-A games last season hardly suggests he's ready to make an impact at the highest level.
