Nick Vincent’s fastball approached the plate at 89.9 m.p.h., but by the time it left Vladimir Guerrero Jr.’s bat it was traveling much faster.

Once it landed, 438 feet away in the batter’s eye at Oracle Park, Guerrero Jr., had his first major-league home run.

The top prospect in baseball started his major-league career quietly, with just two doubles and seven singles over the course of his first 13 games for a .191 batting average and .517 OPS. However, the Blue Jays have been seeing an improved plate approach from Guerrero Jr., of late, leading some to predict a breakout.
