Yosver Zulueta (MLB Pipeline #10, JaysProspectus #9)
Zulueta, a 25 year old right-hander, has stuff that has caught the interest of scouts for some time now but we're still waiting on him to put it all together. He had a 4.08 ERA at Triple-A with an alarming 6.33 walks per 9 innings. The implementation of an automatic balls and strikes challenge system at Triple-A has led to offense ballooning there so it's fair to assume that his ERA and walk rate partially suffered due to that. Despite this, Zulueta did an amazing job of keeping the ball on the ground and had an above average strikeout rate.
On August 15th, the Jays assigned Zulueta to the Complex League to work on a few things. In his 11.2 innings after returning from the Complex League he had a 2.31 ERA, 1.94 FIP, and a much improved 3.09 walks per 9 innings. In these appearances he was throwing his sinker a couple ticks softer (still around 95-96 MPH) and used his new sweeper more. His sinker and sweeper are both really strong offerings and play off each other very well. If he can focus on his command of these two pitches there's still a dominant MLB reliever in here even if he's getting up there in age.
With bullpen arms getting hurt with regularity, it's a fair assumption that we will see Zulueta in the big leagues at some point next year. There's no denying he has stuff to clean up but the upside remains tantalizing and he's established himself as one of the top depth options at Triple-A.
