Watch: Darvish practices pitching left-handed

Either Yu Darvish is having a little bit of fun this offseason, or he's adding a new tactic to an already impressive repertoire.

As if his right-handed dominance wasn't enough for the Texas Rangers starter, Darvish posted a video to his Instagram account Friday that clearly shows him pitching southpaw and connecting with a couple of strikes.

Of course, Darvish could just be keeping his right arm healthy, as the hurler underwent Tommy John surgery on his elbow in 2015. Well, that's what American League batters are hoping anyway.
