The Toronto Blue Jays will call up third baseman and baseball's top overall prospect Vladimir Guerrero Jr. on Friday in time for the weekend home series against the Athletics. Blue Jays manager Charlie Montoyo announced the decision to reporters on Thursday evening. 

The player himself provided a simple acknowledgement of the news: 

The 20-year-old Guerrero is of course the son of Hall of Famer Vladimir Guerrero. This season, Guerrero Jr. has batted .325/.400/.525 in 11 games split between the High-A and Triple-A levels. For his career, he owns an OPS of .943 across parts of four minor-league seasons with 43 home runs and 71 doubles in 287 games. 

Guerrero suffered an oblique injury not long ago that cost him most of spring training, and in some ways that was a tidy development for the Blue Jays. Despite Guerrero being obviously ready, they were poised to start him off in the minors this season in an effort to manipulate his service time and ensure another year of team control before he eventually hits free agency. The injury, though, ensured that Guerrero could be added to the active roster after it was too late for him to log a full year of major-league service time in 2019. 

Guerrero will fill an obvious hole on the Toronto roster. Blue Jays third basemen this season -- Brandon Drury, mostly -- have batted just .215/.255/.355. Guerrero figures to improve upon that and then some right from the start.
