"That's what I care about," Dunn said. "If I'm not driving in runs or scoring runs, that's where I have a problem. I'm not doing it now and it better turn around quick.
"I do feel good at the plate. It's just frustrating for me when I leave so many guys on base and don't drive them in. You know, it's like three or four of these games, personally I had a chance to break it open or tie it or whatever and I haven't been able to get the hit yet."
Dunn went 0-for-4 with two strikeouts on Saturday, although he just missed a first-inning homer, and is now hitting .146 with two homers and five RBIs. He's hitting .182 with four RBIs with runners in scoring position. The designated hitter has noticed fouling off more pitches than usual, pitches he usually puts in play, which is a sign, in Dunn's mind, of not swinging the bat as well as he could.
"I'm out in front a little bit or the ball is beating me a little bit," Dunn said. "I need to find that happy medium and start hitting the ball hard.
"Again, that's what we are talking about what I do, that's my thing. Scoring runs and driving in runs. When I have chances to open games up early or late and not get it done, that wears on me a little bit."
