DUNEDIN, Fla. -- Blue Jays right-hander Marco Estrada believes he has figured out why hitters were having so much success off his changeup last season.
Estrada admitted that after watching video of last year's starts, he discovered an issue with his mechanics. Whenever Estrada threw the changeup, his delivery was a little bit slower compared to the rest of his pitches.
Most people would not be able to notice the slight variation, but opposing hitters seemed to pick up on it. They had more success off the pitch than ever before, and it was one of the reasons Estrada finished the year with a disappointing 4.
