The 24-year-old is ranked the No. 19 prospect in the Blue Jays' system, according to MLBPipeline.com, but his stock has risen recently following a strong run in the Minors. He throws in the low 90s with good command, a plus changeup and a pair of breaking pitches.
"Good pitcher, he has a bright future with the organization," Blue Jays manager John Gibbons said. "He has been pitching well, he was dominating down in Double-A, couple starts in Triple-A and looked really good. So why not? Give him a shot and see where he goes."
The Blue Jays chose Boyd over promoting a more seasoned pitcher from the Minor Leagues like lefty Felix Doubront. The club went with the upside, and if Boyd responds well, then there's a possibility he could stick around for an extended period of time.
This spot in the rotation originally belonged to right-hander Aaron Sanchez, who has been on the 15-day disabled list since June 6. Right-hander Scott Copeland got the first shot at taking his spot, but after a strong season debut, he struggled in the next two outings and lost his spot.
Sanchez likely won't return until after the All-Star break, so there could be four starts up for grabs before he returns. Whether or not all of them go to Boyd remains to be seen, but it's a scenario that has been discussed internally.
"Yeah, why not?" Gibbons asked late Friday night. "If he pitches well, it's his time. Sanchy is back throwing, but I don't know how long he is going to be."
