Vladimir Guerrero Jr., widely considered one of the top prospects in baseball, will be called up by the Toronto Blue Jays on Friday and is expected to make his major league debut, manager Charlie Montoyo announced.

Guerrero, a 20-year-old third baseman and the son of Hall of Famer Vladimir Guerrero, was No. 2 on ESPN insider Keith Law's 2019 top prospects list. The Jays have yet to announce a corresponding roster move.

"It's going to be a great moment. I get goosebumps just thinking about it," Montoyo told ESPN's Marly Rivera. "We have been talking about this for a long time, and it's just so exciting that the moment is finally here.

"I am so happy. This was such an important moment, not only for the city of Toronto and for the Toronto Blue Jays but for our entire baseball community, that the No. 1 prospect in baseball will debut Friday. He is so talented, that the sky is the limit for that young kid. In my case, personally, I am just excited to see him play every day and see what he can do."

Guerrero's father, who played the first eight seasons of his 16-year career with the Montreal Expos, took to Twitter to celebrate the news.

My son! The country that saw you as a child will now see you turn into a big one.

Toronto will host Oakland on Friday for the start of a three-game series, with right-hander Mike Fiers scheduled to start for the A's and Marcus Stroman taking the hill for the Blue Jays.

Montoyo told Rivera that he hasn't decided where he'll slot Guerrero in the lineup.

Guerrero hit .381 with 20 homers and 78 RBIs in 95 games while rocketing through four levels of minor league ball last season.

There was a possibility that he could make the Blue Jays' big league roster out of spring training, but a strained oblique early in spring camp ruined any chance of that.

Guerrero has continued to perform this season with Triple-A Buffalo, hitting .367 with three homers and eight RBIs in eight games, including a home run in Wednesday's game.
