Analysis

Mejia burst onto the scene in 2009, posting excellent numbers at both High-A St. Lucie (44 strikeouts to 16 walks in 50 1/3 IP) and AA Binghamton (47 strikeouts to 23 walks in 44 1/3 IP). This during his 19-year-old season. Signed internationally as a 16 year old, Mejia has developed quickly, although his control was a bit of a letdown when he was promoted to AA. His loss of control continued when he pitched in the Arizona Fall League, posting 16 strikeouts and 13 walks in 14 1/3 IP.

Mejia throws a low-to-mid 90s fastball, which per the scouting report above has excellent movement. He also relies on a good curveball, and also throws a changeup as well. His arm motion, while appearing somewhat violent, also appears to be under control to an extent. He comes with a 3/4 arm angle as well.

His low innings total this season (110 over all 3 levels), has me a bit concerned for his development. It seems to me that he will most likely need at least another season at AA to help improve his durability. I think that the Mets really need to try to get him up to the 140-150 innings pitched level during next season.

Outlook

Mejia could really use a full season at AA, in my opinion. He has only thrown a maximum of 110 innings in a single season, while being promoted extremely quickly. His control still needs some improvement, and a consolidating season at AA would be the best thing for him, in my opinion. Assuming he can continue his success while doing this, I could see him starting 2011 in AAA, with the potential for a callup later on in that season.

Prediction for 2010

8-6, 4.25 ERA, 145 IP, 140 strikeouts, 65 walks (AA)

Expected ETA

2012 at the soonest. If he can’t get his control issues worked out, I could see it taking longer. But he would still be only 22 if he made the Majors in 2012.

  1. While every review I have read gives no doubt bout his electric arm, there are differing opinions on whether he will eventually end up as a closer or stay in the rotation…what do you think from what you know and your experience? Thank you

    • I think it really is based on how he does this season. The fact that he hasn’t really had a jump in innings towards a level near what he would need to provide at the Majors as a starter is what concerns me. But based on what I’ve seen, if he doesn’t make it as a starter, he could conceivably be a good closer. And he’d probably be ready around the time when K-Rod’s contract is up. Definitely a solid fall-back potentially.
