Watch: Osuna leg-presses a scary amount of weight

There's more to pitching in the big leagues than just getting your arm into shape. Ask Toronto Blue Jays closer Roberto Osuna.

On Monday, the 21-year-old posted a video on his Instagram account that shows him leg-pressing a scary amount of weight.

The young hurler is set to pitch for Team Mexico at the World Baseball Classic this March before beginning his third big-league season with the Blue Jays.
