Jersey: #25 for the New Hampshire Fishercats


A question and answer session is available here.

An interview with 1BJW guys available here.

Ranking amongst the Fishercats pitchers:

  • 2nd lowest ERA and 2nd most IP and wins amongst starters, with a 3.63, 136.1 IP, and 8 wins (beaten only by Kyle Drabek in all 3 categories)
  • Allowed the most hits (131) and had the 2nd worst whip amongst starters (1.36) (will be explained later)

Zach has always had questions surrounding whether or not he should be a starter or a reliever. As far back as when he was a junior in college, his role was altered to being a reliever and he did very well from that point forward. As a reliever, Zach used his 2 plus offerings that he throws from a 3/4 arm slot – a 92-96 MPH fastball that has consistent sink to it and a flat out “buckle your knees” plus-plus slider – to go right after hitters and dare them to get good wood on the ball.

The change to the pen came simultaneously with his move from North Central Texas to Texas Tech (moved up to a Big 12 school), and the result was a change from throwing in the high 80s to 92-96 MPH, a huge jump in velocity as he worked more consistently at the top of his range. He also spent some time as the closer in Texas Tech. However, as his time in Texas Tech came to an end, injuries took their tole on his team and his role was once again altered to a starter. He failed miserably over his 2 starts, getting knocked around to the tune of 16 hits in only 9 innings of work.

Once he got to Cincinnati, he was used as a reliever for the 2008 season, but was moved once again to the starting role in 2009 despite cruising through LoA and HiA as a reliever in 2008 (1.08 ERA and 5 saves in 33 IP). There always seemed to be hope that his change up would come around and that he’d be a very effective starter as a result.

So, with yet another challenge in the works, Zach returns to starting and does extremely well this time around,cooking through HiA (2.13 ERA) and AA (1.46 ERA) with ease over 14 starts and 79.1 IP combined. In fact, during his time starting for the Carolina Mudcats that season, hitters only managed a .218 average against him (29 hits in 37 innings). But, for some reason the Reds decided to put Zach back into the pen and moved him up to AAA Louisville, where he only threw 12.1 innings of work (9 games) before being dealt to the Jays along with Edwin Encarnacion, and Josh Roenicke in return for Scott Rolen (the parting gift of JP Ricciardi).

The Jays, not wanting to throw him off-stride too badly, kept him in the pen and in AAA Las Vegas for the remainder of the 2009 season. He struggled some, allowing a .327 average against with a 3.38 ERA over 13 innings of work. So, here he was, wondering what would happen to him in 2010 in the midst of a regime change in Toronto, a new GM at the helm, an ace on his way out of Toronto (Halladay), and many questions about what his role may be within Toronto’s system which was then ranked as one of the 4 worst in MLB and with him being ranked by most experts as the best of the bunch (ranked #1 by Baseball America for the Jays prospects following that season).

The Jays decided from the onset of the new era, under the guidance of Alex Anthopoulos, that expectations and roles would be clearly defined for all of their players and pitchers. Therefore, it comes as no surprise that when asked about what direction management gave him going into the 2010 season, which meant a demotion to AA New Hampshire,  Zach responded as follows in an interview posted on BusLeagueBaseball:

"“They talked to us in spring training, individually, and they told me that I would be starting here. They didn’t really give me a time-frame or anything, but it was just like, they told me straight up that this is where I was gonna start from the very beginning. I thought that was cool of them to give me an insight on what their thoughts were. So yeah, they told me, and to me it’s not a big deal. It’s one of those things, no matter what level you’re at, you’ve gotta pitch good to get where you wanna be. I mean, wherever I’m put, I’ll just play the best that I can, and whatever happens, happens.”"

From the same interview, Zach’s thoughts on whether he’d rather close or start are as follows:

"“[pauses, sighs] It’s tough to say. [pause] Honestly, I guess I’d say I’d rather start. You have more impact on the game that you do pitch in because you can go longer, 6-7-8-9 innings, hopefully. On the other hand I wouldn’t have any problem being a closer. I’ve done both, in college and professional ball, and I like both sides of it. I guess if I had to pick I’d say a starter, but either way it’s fine with me.”"

He began the 2010 season as the #1 rated Jays prospect, starting once again after being shifted to the pen often over his entire career, and with a new organization in New Hampshire. Thankfully for his development, Zach started during the entire season, making 26 starts and throwing 136.1 innings. However, it wasn’t an easy road to success for Zach during that season, as he started the year horribly.

Here are Zach’s stats through May in 2010:

It takes a lot of patience for an organization like Toronto to continue to throw him out there as a starter after that start to the season at a level he should have easily dominated. He was allowing more than 1 hit per inning overall and was walking way too many batters. But, the Jays had made a commitment to him at the beginning of the season, stating that he’d be in AA and that he’d be a starter, and that’s where he stayed. From that point forward, Zach was simply dominant, although he did tire some at the end of the season, as he put up the following stats:

And here begins the battle of the opinions. Will Zach be able to replicate his 2nd half of 2010 efforts in AAA or in The Show? Or, will he eventually be moved to the pen and become what could be one of the most dominant closers in all of MLB? Well, now that we know Zach’s preference, and we do know that most organizations value top-flight starters more than relievers, we have to assume that he’ll at the very least get a chance to prove himself at the highest levels before any further move to the pen is made. With no durability issues, no health issues, a plus offering and one plus-plus offering, he should get every chance to start. His change up now grades as average after a ton of work was done with it in 2010. He trusts it more than he ever has now that he’s had the time to throw it more often, and it’s been said to have some cut to it.

The one portion of Zach’s stuff that worries me is the fact that he was switched back and forth from the pen. Any time that you ask a pitcher to go back-and-forth between an all-out effort delivery to a long winded starting role, you’re having an impact on his mechanics. I’m not saying that it will result in an injury without a doubt, but there could be some complications down the road as the Jays increase his work load past the 150-170 inning marks. Will he be able to keep working at 94-96 MPH during that long of a stretch? And if he can’t, will he “pitch” more effectively, or will the loss in velocity render him ineffective? These are important questions to ask, because if the Jays don’t believe he can keep pitching effectively with a drop in velocity, they need to switch him to a relief role now. If not, he’ll only be placed back in the role when it’s too late and his arm has been taxed as a starter to the point of diminishing his velocity for the long term.

That’s what makes the 2011 season the turning point in Zach Stewart’s career. He’ll be pitching at levels, as a starter, that will allow for a more thorough look at whether he’ll be able to remain a starter or not. The quality of the competition is not the only thing that will get higher this season for Zach, it’s the pitch counts, length of games (assuming he goes deeper into games), and his overall innings totals. How he responds to all of those changes will undoubtedly set the course for the remainder of his career, whether it be in the rotation or in the pen.

It’s likely that many other organizations would have given up on Zach and kept him on in a relief role instead of starting him in AA all of 2010. However, the Jays remained true to their word and gave him a shot to improve and are now benefiting from more depth in the rotation as a result of their patience. The 2011 rotation is already young and fairly slim on experience, so this fact, combined with other options that no longer have options and would have to clear waivers to make it back to AAA, leads me to believe that he may begin the year in AAA. However, don’t be surprised if he is one of the first pitchers recalled when the season gets going, as he’s earned a lot of respect as a starter and his time to prove himself as an MLB starter has come after a long and flip-flop filled amateur career.

Expected 2011 Team: AAA Las Vegas or Toronto Blue Jays

Ultimate ceiling IF he puts it all together: #2 starter or closer

Everyone has an opinion when it comes to Zach’s landing spot when he gets to The Show, but nobody doubts the fact that he’ll get there and will find a role. His demeanor and stuff both allow him to start or pitch in relief effectively, but my bet still remains on starting until such time as he either proves ineffective against MLB hitters, or proves to be effective. Only at that time should the Jays be amenable to either keeping him in the rotation or switching him back to a relief role for the final time.
