In three of those games, Gennett saw at least 20 pitches. His 13-pitch at-bat on Saturday night essentially knocked Reds starter Mat Latos out of the game after six scoreless innings, and helped the Brewers score two runs apiece in the seventh and eighth innings for a comeback win.
"It's not because of the leadoff spot," Roenicke said. "I had a discussion with him a week and a half ago about him being more selective with that first pitch. It doesn't make any sense at all to go up there and see a breaking ball, a good breaking ball, and swing at it, hit a ground ball and make an out.
"It makes no sense at all, your first at-bat of the game. What are you going to do your second at-bat? Are you going to go up there, probably 'take,' and then it's going to be a fastball right down the middle and you're taking it. So the discussions I had with him are more on just being selective; it's not because he's leading off."
Gennett was open to adjustments.
"This guy can really hit," Roenicke said. "He really can. But if he ever becomes a guy that understands the strike zone, he's going to hit over .300. It's like the old Ted Williams box with the batting averages. If you can show a guy that, 'You hit .200 here and you want to swing at the first pitch, and yet you hit .400 here, why wouldn't you wait for the .400 pitch instead of trying to hit this one on the corner?'"
