It's the longest winning streak for the Diamondbacks since they reeled off eight consecutive wins from August 9-17, 2002.
Dellucci reached on an infield hit and scored a run and Womack delivered an RBI single off Astros starter
(4-7) as Arizona rallied for three runs in the second inning.
"Everyone has been swinging at good pitches, so we have to keep it going," Womack said. "You just gotta go up there and get a good pitch to hit. You can't control it after that. You got to put yourself in a situation to be successful."
Dellucci recorded his third career four-hit game and first since May 23, 1999 at Colorado. Womack's four-hit effort was the 12th of his career and second in 10 days.
Arizona established a season high for hits in a game with 19.
"That is a good blueprint for winning - having sustained rallies, multiple hits in an inning," Diamondbacks manager
said. "Even some of the outs, the runners advanced. There were a lot of good things offensively."
The Diamondbacks had a 5-4 edge in the sixth with one out and one on when Cintron smacked a 1-2 pitch over the left field wall, highlighting a three-run outburst.
"I don't swing for homers, he threw me a mistake pitch," Cintron said. "It is about my approach and my timing. My timing is so perfect right now. I can see every kind of pitch and I make the adjustment right away."
"I am not surprised anymore," Brenly said of Cintron. "He has a quick bat. He doesn't try to hit home runs, but his bat is so quick."
Kata's three-run homer with two out in the eighth capped the scoring. He finished with a season-high four RBI.
"Anytime I can drive in runs is a bonus," Kata said. "But me and Tony at the top of the order are just trying to get on base and have the guys behind us drive us in. ... They always say hitting is contagious and it is true."
(6-3) picked up his third straight win, despite allowing four runs and seven hits in six innings.
Houston second baseman
was hit by a pitch from rookie Steve Randolph in the top of the seventh and suffered a broken left wrist.
"It is very tough and very painful," Vizcaino said. "It happened when I am starting to play better, but that is baseball. I knew right away it was something bad, when you hear, 'pow.' It was really painful. So I knew something was wrong. I saw the pitch, but it was too late."
Following the game, Vizcaino was placed on the 15-day disabled list. He is expected to miss four to six weeks.
doubled twice for the Astros, who have dropped two in a row after winning three straight.
