Mazey spent much of the 2010 preseason pleading with Winkler to put his pitches down in the strike zone. Winkler, who was 7-1 with a 4.15 ERA as a freshman, wouldn't play along.
"He'd always talk to you right after you got done throwing, whether it was good or bad," Winkler said. "He didn't say one word to me for two weeks."
Once he realized what was happening, Winkler took Mazey's advice.
"I wanted him to be proud of me when I threw, but it was something I could tell he was upset about," Winkler said. "Instead of trying to be stubborn about it and trying to do it my way, I determined I was going to be better off if I did it his way."
He was 12-3 with a 3.39 ERA in 2010 and 8-2 with a 1.39 ERA a year later. Winkler ended up being drafted by the Baltimore Orioles in the 10th round in 2011.
"He does a great job getting them to trust him," Schlossnagle said.
"What's that they say? 'They're never going to care what you know until they know that you care.' He really lives by that and the kids trust him. If he said, 'Hey, the best thing for you to do is not be left-handed anymore,' they'd start throwing right-handed."
Holle changed only his throwing angle. He was 8-5 with one save and a 5.19 ERA in his career, but he had good stuff and could use his 6-foot-8 frame to at times overpower.
"We were trying to figure out how they would keep, for whatever reason, getting on base," Holle said.
"He said, 'Let's get some more movement,' so he dropped my arm down a little bit and 4 or 5 m.p.h. came with it."
Holle struck out 38 and walked 10 in 34 2/3 innings in 2010. The Brewers then drafted him in the 11th round.
"There won't be one part of the game that they haven't covered in practice," Schlossnagle said. "Randy's a proven commodity. They got really lucky."
