Independent Aroldis Chapman Debut Report

Baseball Prospectus.com reviews Aroldis Chapman’s professional debut this week:

Aroldis Chapman, LHP, Reds (Triple-A Louisville)

While the best pitching prospect in baseball was making his professional debut in Altoona, the best left-handed prospect in the game was in equally glamorous Toledo, putting the first numbers on his official record. Chapman had better overall numbers than (Stephen) Strasburg, and he was throwing a bit harder as well, getting up to triple digits with his fastball and dominating primarily off of that while also flashing a solid slider. For a guy who has had occasional control issues, that certainly wasn’t the case on Sunday, and if that remains the case, he could beat Strasburg to the big leagues.

  1. Sounds like whoever wrote that didn’t even watch the game, because Chapman was incredibly wild. If no one swung the bat in that game, he probably would have walked 6 or 7. He was missing the target put down by Castillo by 12-24 inches at times. The Mudhens had to cheat though to catch up and it led to them really expanding the zone. The numbers looked nice, but he was all over the place in that start, control was not good.

  2. @Doug Gray: I agree, but if the other team is swinging at everything, wouldn’t it make sense to keep it out of the zone. I’m not saying that I believe that was what he was doing, but merely suggesting that it could have played a part in his “wildness”.

  3. @Doug Gray: Most of the ace/strikeout pitchers in baseball, which Chapman projects to be, possess incredibly high O-Swing%s. O-Swing% measures the amount of pitches hitters swing at that are outside the zone. It’s safe to say that most hitters cheat in order to hit these pitchers and therefore, expand their strike zones. I believe it’s a good thing that they were swinging at so many balls.

      There is a difference between setting up outside of the zone and trying to get them to chase and setting up on the outside corner and them swinging and missing a pitch 6 inches inside.
