MLB Sends All-Star Message to Blue Jays' Vladimir Guerrero Jr. originally appeared on Athlon Sports. The Toronto Blue Jays are in the middle of an interesting season. They sport a minus-10 run differential, yet boast a solid 41-36 record and sit in third place in an extremely competitive American League East.

Vladimir Guerrero Jr.’s slugging metrics have been underwhelming, but the underlying data suggest he’s poised for a breakout starting tonight.
