CINCINNATI -- Kaz Matsui sparked Houston's seven-run rally in the fourth inning with a two-run single and the Astros coasted to their fourth straight victory 9-3 over Cincinnati.
Houston has won four in a row for the first time since last May.
The Astros have scored 36 runs in those four wins.
Ken Griffey Jr. hit his 597th career homer off Chris Sampson for
the only bright moment for the struggling Reds, who changed general
managers before the game. Walt Jocketty took over for Wayne
Krivsky, a show of impatience by team owner Bob Castellini.
Sampson is 1-and-2 with the win. Reds starter Bronson Arroyo
fell to 0-and-3 after getting knocked out in the fourth inning.
