VIDEO: Vladimir Guerrero Jr Mashes 1st Career Grand Slam Against Tigers

All that power young Toronto Blue Jays star Vladimir Guerrero Jr. flashed during the Home Run Derby wasn't just for show! The former top overall prospect mashed his first career grand slam against the Detroit Tigers, erasing a 5-1 fifth inning deficit.

It was bound to happen eventually. There was simply no way his power wouldn't come into play with the bases juiced. It was an absolute moonshot too. He sent Gregory Soto's 1-2 offering 441 feet away from home plate.

Guerrero Jr. hasn't quite lived up to expectations in his first year in the big leagues, but perhaps this is just the type of spark that he needs to go on a massive tear.
