Astros 5, Reds 4
CINCINNATI (AP) -- Who can explain this?
Roy Oswalt got his 19th career victory against the Cincinnati Reds on Monday night, leading the Houston Astros to a 5-4 victory that left everybody amazed by one of baseball's most mind-boggling marks.
How could any pitcher go 19-1 against a team?
"I have no idea," said Oswalt (5-2), who gave up a pair of solo homers in seven innings. "The good thing is every time I pitch against them, I get run support. I hope it doesn't change."
Oswalt's success against the Reds is unprecedented. The right-hander won his first 15 decisions against them, and improved to 19-1 career on Monday.
"Have you see Roy pitch?" Houston's Lance Berkman said. "I wouldn't be surprised if he's 19-1 against anybody. He's the best in the game, as far as I'm concerned."
He'll get no argument from the Reds, who thought they had Oswalt in trouble after Adam Dunn and Alex Gonzalez hit back-to-back homers in the second inning -- only the second time in Oswalt's 22 career starts against the Reds that he gave up two homers.
"He's just so good," Dunn said. "We jumped on him early, but to his credit, like he always does, if you don't get five right there, you're not going to get it."
After giving up the two homers, Oswalt was determined to stop the Reds from getting any more runs.
"Coming out of the bullpen, I felt better than I did in a long time," Oswalt said. "The ball was jumping out of my hand. My curve was great. I thought I might go seven or eight innings without giving up a hit."
Dan Wheeler gave up Gonzalez's two-run homer in the ninth before getting his sixth save in seven chances.
Kyle Lohse (1-3) matched Oswalt until the eighth, when Craig Biggio led off with a single. After Mike Stanton walked Berkman, Coffey sprinted from the bullpen to the mound and gave up Scott's homer to right field on a full-count changeup that was right down the middle.
It was the latest meltdown by a bullpen that has just one save since April 15.
"I was going after him," Coffey said. "I was thinking, I've got him right here. Let's get him out."
Before the game, Reds manager Jerry Narron explained how a pitcher like Oswalt could do so well against one team.
"You've got to be very good," Narron said. "You've got to have some breaks. The offense has to do some things for you. A lot of good things have got to happen for you."
Until the eighth, things seemed to be working against Oswalt.
The Astros tied it at 2 in a wacky fourth inning that should have produced a lot more. The inning started with something familiar -- Berkman's leadoff homer, his 13th at Great American Ball Park, the most by any opponent. Berkman has 36 career homers and 104 RBIs against Cincinnati, his highest totals against any team.
The odd followed.
Carlos Lee doubled and Scott walked. Hunter Pence then doubled to center, but Lee held up to make sure Josh Hamilton couldn't get to the ball. By that time, Scott was only a couple steps behind Lee and shadowed the lumbering outfielder all the way home.
Lee slid in before catcher Javier Valentin's tag, but Scott was out when he went in feet-first an instant later. Scott got up smiling at the way the bizarre play unfolded.
"I just started yelling at him: 'Go, go, go, go, go!" Scott said. "I was yelling at him all the way around third. I started laughing. At least one of us scored."
The smiles vanished after the Astros went on to load the bases, but Adam Everett was thrown out by Valentin after he strayed too far away from second on Oswalt's missed bunt attempt. Houston scored only two runs out of a homer, two doubles, a single and two walks.
Bluffton University's baseball team watched batting practice, and coach James Grandey threw a ceremonial pitch to Reds catcher David Ross. Five Bluffton players were killed in a bus crash in Atlanta. ... 3B Ryan Freel dived into the first row of seats to catch Berkman's foul in the first inning. He dived in again in the second inning while trying to get Adam Everett's foul, and presented one of his bats to the fans he landed on after the inning.
