Colon is showing big signs of regressing. He is down almost 3 MPH across the board in the last 6 weeks and he is losing command of his sinker. His slider shows regression as well and is now straightened out.
Check the polarity of the two pitch graphs. One from June 11 and one from his recent start. Granted he still has command of his four seam fastball but there are definite signs that he is not trending well here. Against a dead red team like the Jays this cannot be a good thing.
