Possibly, but I want to know how the effectiveness of his sinker has shifted each season.
If his sinker loses effectiveness, then he'll just go down the Danny Graves road. When Graves' sinker was working in his prime, his HR/FB% was around 10 percent. When Graves' sinker went down the toilet, his HR/FB% jumped up beyond 15 percent, and that's when everything blew up.
