Drew Storen threw a pitch right through Russell Martin's glove

Drew Storen's second pitch to Yasmani Grandal to lead off the ninth inning of the Dodgers-Blue Jays game was clocked at 91 mph. It was, allegedly, the slowest pitch he threw in the at-bat. But what if it was actually thrown much faster than 91 mph -- what if was actually the fastest pitch ever thrown in MLB history?
I mean, how else could it have torn right through Russell Martin's glove?

Even the fastest pitches don't typically burst though catchers mitts, so it stands to reason that this was going at least twice as fast. We're talkin' 200 or 300 mph, probably. That's the only explanation. 
Storen ended up walking Grandal on four pitches -- only one of which broke a glove -- but he ended up earning his second save of the season and the Blue Jays won, 5-2.
But he might be in line for even more saves this season, you know, if he keeps throwing 200 mph.
