A year after absolutely dominating with his Four-Seamer - we're talking a pVal of 24.3 - things got messy last year and he ended u p with a low 3.7 mark for the pitch. What happened? Well, across all of his pitches, Cole lost movement and his Four-Seamer was no exception. The result was more contact inside the zone, fewer whiffs, more line drives and fewer grounders. It's not a dramatic shift, but extrapolate the change over the large sample and it's the difference between a very effective pitch and an okay one. It's possible it was due to injury and it'll return this season, but it's a bit worrisome.
