"He is a coachable hitter, but there is a feel to hitting," Roenicke said. "Some guys have good instincts on when to take pitches, they have a good idea of the strike zone. If you tell them to 'keyhole' a pitch, they know what to do. They know that there is only this little area that they are going to swing at a pitch.
"Well, probably there are only two [hitters] in your lineup that can do that. The other guys, you're telling them something that makes sense, but they can't do it. They can't go up there and say, 'I'm not going to swing at a pitch that's on the outside corner. I'm going to wait for that mistake.' That's always the ideal hitter, but they're not all that way in the big leagues. It's a fact. Most of them aren't.
"I think what Dave [Sveum, Milwaukee's hitting coach] is doing with him lately, trying to get him to go the other way, that's huge for Yuni. I think that's what he needs to do. When his mindset is on going the other way, I think he's going to get more hits."
Entering Tuesday, Betancourt had swung at a Major League-high 42.8 percent of first pitches, just above the Orioles' Vladimir Guerrero (42.6 percent) and the Cubs' Aramis Ramirez (42.3 percent). He was batting .228 with three home runs and 20 RBIs.
Asked during Spring Training about his habit of swinging early in the count, Betancourt explained, "It's in my blood. Latin people don't walk too many times. We just go up there and swing."
"There are times when it's smart for him to go up and take a pitch," Roenicke said, "but you have to have a feel for that stuff. It's hard to just dictate to a hitter exactly what he has to do every time, because then he loses that feel of, 'Hey, I'm 1-0, I feel really good against this guy, I want a good pitch and I want to hit it.'
"When he was hitting last year, there wasn't a whole lot of thought going on with him, as far as people making him do things. There was his last year in Seattle, and it caused problems. I don't want to do that."
