Cincinnati ? Ken Griffey Jr. hit his 569th career homer Thursday, 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 Houston Astros.

Houston won the first three games of the series, improving to 5-0 at Great American Ball Park this season.

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.

Cincinnati pulled ahead 7-0 after three innings against starter Matt Albers (1-2) and held on in spite of more bullpen struggles. Adam 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.

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. David Weathers recorded the last five outs for his seventh save in eight tries.
