Now that his hand is fully healed, Ken Griffey Jr. is climbing the home run list again.

Griffey hit his 569th career homer yesterday, a two-run shot that tied him for ninth place on the career list and helped the Cincinnati Reds get a breakthrough 9-5 victory over the visiting Houston Astros.

Houston won the first three games of the series.

Pitcher Woody Williams and the Astros make themselves at home when they come here. Williams called a vendor over to the dugout and bought four bags of peanuts during the first inning, sharing them with teammates.

Griffey and Adam Dunn led the Reds to their elusive first win.

Cincinnati pulled ahead 7-0 after three innings against starter Matt Albers (1-2) and held on. Dunn hit a three-run homer, his sixth in the last 11 games, and added a triple and a double, coming up one single short of hitting for the cycle.

Griffey had a sacrifice fly and a two-run homer off Albers that left him tied with Rafael Palmeiro on the career list. Harmon Killebrew is eighth at 573.

"Just keep plugging away," Griffey said. "My thing was, I was just trying to get the guy home from third, and it just happened to go out."

The outfielder has been on a tear since he moved back into his accustomed third spot in the batting order. Griffey, 37, has hit safely in seven of those eight games, with four of his six homers.

He missed most of spring training because of a broken left hand, suffered last December. The injury wound up helping him as a hitter.

"I wouldn't recommend it as a way to learn patience, but when you break your hand, you don't want to be swinging at too many pitches early," Griffey said. "It hurt the first 3 weeks of spring training. Look at how I took batting practice. The first couple of times, I didn't swing at very many balls."

Aaron Harang (5-1) struggled to hold the early lead, giving up Chris Burke's three-run homer as Houston cut it to 7-5. Then, the Reds sweated out more bullpen drama.

The Astros loaded the bases with one out in the eighth off lefthander Mike Stanton. Closer David Weathers escaped the threat after a frightful moment - pinch-hitter Morgan Ensberg's potential grand-slam drive hooked foul down the line.

Ensberg took a few steps from the plate and pointed fair with his right hand, then gave up when he saw the ball hooking.

"Not close enough," Ensberg said. "Off the bat, I thought I might have a chance. I could tell pretty clearly it was going to be foul halfway [toward the pole]."

Weathers recovered by striking him out on the next pitch, then finished it off for his seventh save in eight tries.
