Hero: Ryan Dempster (1-4) had his second straight solid start, allowing two runs (both earned) on five hits while striking out four and walking none.
"I'm doing a better job of executing pitches," Dempster said. "I was able to keep the ball down, for the most part, today."
Goat: Starlin Castro, back in the two hole after a game off, continued to slump, going 0-for-4 with a strikeout and leaving six runners stranded on base. Castro has just two hits in his last 25 at-bats (.080 BA), dropping his season average to .300.
The 21-year-old shortstop came to bat with the bases loaded and two outs in the bottom of the seventh against Cincinnati reliever Sam LeCure, but rolled to third for an inning-ending fielder's choice.
"He's just not very patient," Cubs manager Mike Quade said of Castro. "He's expanding the strike zone too much. As good as he is, guys who pitch at this level will take advantage of that if you're not disciplined enough."
Key Play: The Cubs, trailing 1-0 with two outs in the bottom of the third against Cincinnati starter Johnny Cueto (1-0), loaded the bases. But Aramis Ramirez flew out to left to end the threat. Ramirez is 0-for-13 this season with runners in scoring position and two outs.
Is it time to make an adjustment in your approach, Aramis?
"That's what I told (Carlos) Pena today -- keep swinging and keep doing what you're doing and don't change anything," a stubborn Ramirez told reporters after the game.
