Way back on August 1st, I wrote my very first piece at VEB (Carlos Martinez is still experimenting). I looked at his success, or lack thereof, against left-handed hitters and his different locations on the rubber, which affected his release points. However, I did this with only the context of his slider. Today, ahead of his start against the Chicago Cubs, I want to examine his changeup.
With more data than we had six weeks ago, we should be able to judge both the effectiveness of the pitch and what adjustments, if any, Martinez has made since then.
