The Diamondbacks' Lourdes Gurriel Jr. hit a home run off a 103.9-mph pitch by the Padres' Mason Miller. It's the fastest pitch to be hit for a home run since MLB started tracking the stat.

But no pitcher is invincible no matter how hard he throws. And Diamondbacks outfielder Lourdes Gurriel Jr. proved just that on Tuesday night when he tied the game in the eighth inning by crushing Miller's 103.9 mph fastball for a two-run homer.
