Borucki has missed time with various arm ailments since he was drafted in 2012; the outing I saw was just his 20th appearance as a Blue Jays farmhand. Despite the extended layoffs, Borucki is advanced for a pitcher in short season ball. He lives around the edges of the plate with all three pitches, and while he can sometimes err towards the side of caution when attacking hitters, he rarely makes a mistake in the zone. He can throw his fastball and both secondaries for strikes, and he showed advanced pitchability: you just don't see too many starters who can add and subtract velocity on their fastball or depth on their curve at this level.
If Borucki can stay healthy, the Jays could have a mid-rotation starter on their hands, although it looks like the organization will be taking it slowly with him. He’s still building up arm strength — he didn’t make it out of the third inning and his average fastball velocity was quite a bit lower than his highest readings — but both his slight build and injury history suggest that he’s unlikely to develop into a workhorse. He could have three average or better pitches at full maturity though and he knows how to pitch, so there’s plenty of upside if it all clicks, even if he proves best in doses.
