Records: Reds 10-15, fifth place in National League Central; Rockies 14-11, second place NL West.

The arms: Today - RHP Chris Reitsma (1-0. 0.00 ERA) vs. RHP Jason Jennings (1-3, 7.92); Wednesday - RHP Ryan Dempster (1-1, 5.34) vs. RHP Aaron Cook (1-2, 5.79); Thursday - Jeff Austin (0-1, 6.00) vs. Nelson Cruz (3-1, 4.61).

The bats: Don't give the Rockies' Larry Walker anything to hit. He's hitting only .271 so far this year, but he's a career Reds killer - .343 with 125 HRs in 125 games.

The rest: The Rockies' Justin Speier is showing his stuff in the set-up role - Sunday in the Rockies' 6-3 victory over the Cubs, he worked a perfect eighth with what was only a one-run lead at the time. ... The Rockies swept their three games with the Reds last year at Coors.

The quotes: Reds Manager Bob Boone: "The humidified baseballs seem to have changed (the arena-ball aspect of mile-high Coors Field) a little bit, but I haven't been there enough to know how much. It's not a fun place to manage; it's a fun place to hit -- if you're blastin'. No lead is ever comfortable."

Reds outfielder Austin Kearns: "I don't like it when you go into a park and people say, "It's a home run park," or "The ball really flies here." That can get you thinking so many different things. I'm just trying to stay through the ball, and hit it the other way, just trying to get my feel back." Kearns hasn't had an RBI or a homer in his last six games.
