HOUSTON (AP) - The Houston Astros had it all going their way for four innings.
They lost a 6-0 lead and then had catcher Humberto Quintero end up on the 15-day disabled list after a scary home plate collision.
Juan Miranda hit two two-run homers to lead the Arizona Diamondbacks' rally to a 7-6 victory Friday night.
Arizona's game-winning run scored on the play in the seventh inning when Ryan Roberts collided with Quintero at home plate. Quintero left the game with a right ankle sprain and was placed on the 15-day disabled list.
``We know there's no fracture,' a relieved Astros manager Brad Mills said.
Quintero's injury came just two days after San Francisco catcher Buster Posey was hurt in a collision at home plate and is likely to miss the rest of the season. The reigning NL Rookie of the Year broke a bone in his lower left leg and tore three ligaments in his ankle Wednesday when Florida's Scott Cousins ran into him to score the winning run on a sacrifice fly.
Giants general manager Brian Sabean called on baseball officials to review rules regarding home-plate collisions, and suggested a simple - but significant - change.
``You have to slide into other bases,' Sabean said. ``Why shouldn't you have to slide into home plate?'
Friday's collision occurred just after Chris Young hit an infield single that bounced toward Astros reliever Wilton Lopez. As he got up to make the catch on Lopez's throw home, Quintero planted his left foot on Young's bat, causing Quintero to lose his balance momentarily just as Roberts approached.
``The bat made me slide back,' said Quintero, who was replaced by J.R. Towles. ``(When colliding with Roberts), it pushed my knee and ankle back.'
Lopez's throw was deflected by Roberts, and Kelly Johnson scored as Quintero grimaced in pain on the dirt as the ball rolled unclaimed toward the Astros dugout.
Quintero did not see any malice on the play.
``I think it was an OK play,' Quintero said.
To replace Quintero, the Astros purchased the contract of catcher Robinson Cancel from Triple-A Oklahoma City.
It was the Astros' biggest blown lead for a loss of the season, and it marked the fifth time they found themselves losers despite leading by at least four runs in a game.
Michael Bourn went 3 for 5 with three RBIs and two runs scored, and Jeff Keppinger was 2 for 4 with an RBI in his first action of the season since recovering from offseason foot injury.
Astros starter Brett Myers went from solid to rocked at the expense of Miranda, who was 2 for 5 in his first career multihomer game.
``A couple of leadoff walks (one each in the fifth and sixth innings) did him in,' Mills said. ``That's not like him. He does such a great job getting it back. Tonight wasn't the case.'
Miranda took Myers deep in the fifth inning and again in the sixth to get Arizona within two runs after a shaky start by right-hander Daniel Hudson afforded the Astros a 6-0 lead through the first four innings.
``To Miranda I think I threw pitches that I wanted to throw,' said Myers, who lasted 5 2-3 innings. ``The fifth and sixth innings, those were pitches I thought were good pitches.
``The guy put a good swing on them.'
The Diamondbacks went ahead for good later in the inning on Young's two-run infield single that scored Roberts and Johnson and sent Quintero for X-rays that came back negative.
``I can be good to go in 7-10 days,' he said.
The Diamondbacks have won 12 of their last 14 games.
Arizona closer J.J. Putz pitched the ninth for his 15th consecutive save.
