The head-to-head opportunities are dwindling. Second-place St. Louis is a game and a half ahead of Cincinnati. The Cardinals host the division-leading Pirates for three games next weekend, completing their season series. The Reds play Pittsburgh six times in their last nine games.
The trio has been in a tight pack atop the division most of the season. Currently, all three are in position to make the playoffs.
And now, the Reds have a new way to win a close game.
"Watching Billy run — I can watch that every day," Frazier said.
They considered calling up the 22-year-old Hamilton last September, but decided he wasn't ready. A year later, he made good on his first steal attempt and decided a game full of tough pitching and sensational defense.
Michael Wacha, the Cardinals' top draft pick last year out of Texas A&M, made his fifth career start and blanked the Reds on three hits through six innings.
The Cardinals' lineup was back to full strength. Carlos Beltran was back in right field after missing two games with a sore back. Molina was back in the lineup after leaving Monday's game with a sore left wrist.
Bailey is in a good stretch, winning his last five decisions. He held the Cardinals to five hits over 7 1-3 innings during a 10-0 win in St. Louis last Wednesday.
Bailey escaped an early threat. Matt Carpenter opened the game with a single, and Bailey walked Beltran on four pitches, bringing up Matt Holliday. The left fielder has a .375 career average against Bailey, but struck out swinging. Allen Craig grounded into a double play.
Defense had a lot to do with keeping this one close. No surprise there — St. Louis has the fewest errors in the NL, Cincinnati the third-fewest.
NOTES: The Cardinals called up RHP Carlos Martinez, LHP Tyler Lyons, INF Ryan Jackson, INF Brock Peterson and C Audry Perez. ... Baker said LHP Tony Cingrani will start the final game of the series on Thursday. RHP Greg Reynolds replaced Cingrani when he went on the DL with a sore back and was on turn to start. Baker said Reynolds will be ready if Cingrani has problems. ... Reds RHP Bronson Arroyo (13-10) starts Wednesday's game against RHP Shelby Miller (12-9). Arroyo is 0-3 in four starts against the Cardinals this season and 8-16 for his career.
