They went over tape from 2011, when Scherzer began the year undefeated in April with a 4-0 record and a 3.19 ERA. What they learned is that Scherzer needs to tweak his windup.
"You could see a lot of difference [comparing this year to last]," Leyland said. "His hands are separating a lot different than they were at a lot of different points in his delivery.
"Now, is that the total answer? I don't know that, but there is some flagrant differences. We hope we've corrected that, and the best part about it is he recognized it right away."
Scherzer said along with his hands, his front side is opening up too early, which is why his control is suffering. Aside from that, Scherzer fully believes "everything is fine" and that his stuff is good enough to return to his 2011 form, when he finished 15-9.
"Just go out there, fix it, do it and pitch," he said. "That's all it comes down to. Just have that type of mentality. I know I'm a good pitcher in this league. I'm very capable, and I believe next start I'll be right where I need to be."
