He may have been called up late last season had it not been for a knee injury.The Blue Jays are 11-14 and in third place in the American League East. It may have come a year late, but Vladimir Guerrero Jr. is on his way to the big leagues.The Blue Jays announced Wednesday that MLB’s No. 1 prospect has been called up after a short stint at Triple-A Buffalo. Guerrero was batting .367 at Triple-A Buffalo before he was called up.He was hitting .333 on the season across two levels but 15 of his at-bats came at High-A Dunedin as part of a rehab assignment, so they brought down his average a bit, as he was trying to get his timing back.This comes one day after Blue Jays fans found out the team’s No. 2 prospect, Bo Bichette, suffered a broken left hand so this news came at a pretty good time for the city of Toronto.
