As we near the halfway point of both the major league and minor league seasons, it's time to take our third look at how the members of the Blue Jays' 40-man roster not currently with the big squad have performed. You can click here to view May's update.


Yosver Zulueta: After a much improved May, Toronto's number 3-prospect Yosver Zulueta, unfortunately, couldn't continue that into June. Throwing for a 4.40 ERA and an incredibly high WHIP of 1.81 Zulueta still clearly has a lot of work to do. Now exclusively a 1-2 inning reliever, Zulueta hasn't been able to effectively eliminate base runners this season, and while his 10 base-on balls are better than the 15 he had in May, he also hit four batters and threw three wild pitches. A huge contrast from May was the fact that opponents were also reaching by getting hits, with his opposing slash line improving from .167/357/.222 to .327/.469/.367. Zulueta continues to punch out batters (46 in 40 innings) and The flame-throwing Cuban is still on the team's top-30 prospects list for a reason but at 25 is going to have to significantly decrease walks if he wants to make an impact in the Jays bullpen.

Trent Thornton: Recently demoted back to Triple-A, Trent Thornton has returned from his mid-May IL stint with incredibly impressive numbers. Since his activation Thornton has thrown a total of 8.1 innings in six appearances between Buffalo and Toronto, allowing just a single earned run and striking out 10. His curveball has a ton of movement on it, but it's his sweeper (of which he's thrown 16 for the Jays and all against righties) which has been his bread and butter (excuse the pun). Thornton has yet to allow a hit off of the pitch and is generating a 36.4 whiff percentage. He did issue four walks in three minor league innings before his promotion, but only issued one free pass with the big league squad, so his early season location issues seem to have dissipated. Toronto'sbullpen has a lot of question marks right now, and Thornton is part of what seems like a never-ending revolving door. With minor-league options, unfortunately, he ends up being a casualty of said revolving door, but with his continued success he should find himself another big-league opportunity.
