OAKLAND -- The A's locked up reliever Sean Doolittle with a contract extension Friday afternoon, just hours before prized prospect Sonny Gray showed once again that he also has the makings of a franchise cornerstone.

Gray kept the Houston Astros in check for six innings and cruised to his third victory without a loss this season, in large part because of a seven-run outburst in the first inning that catapulted the A's to an 11-3 win at the Coliseum.

A matchup between the top pitching prospects from the respective organizations -- Gray and Houston's Jarred Cosart — lasted less than one inning.

Gray did his part. It was Cosart who failed to live up to the hype. He departed after 39 pitches and seven runs on his ledger.

As so often is the case, the A's relied upon a formula that they call power and patience.

Wait for certain pitches, take some walks along the way and tee off when the desired pitches arrive.

"That's how you get starting pitchers out of the game," A's manager Bob Melvin said. "That's how you get to bullpens early. That's how you can beat good starting pitchers. ... That's been an attribute of ours for the better part of two-plus years now."

It worked to perfection Friday. Yoenis Cespedes started the A's onslaught with a two-run single after Cosart walked the bases loaded. Alberto Callaspo added a three-run home run and Josh Reddick drilled a two-run shot before Cosart got yanked with one out.

The A's batted for so long in the first inning that Gray warmed up in the bullpen, while Cosart labored on the mound.

Gray made it through the long wait just fine. Not that he cared, given the fact he benefited from the offensive explosion and it made his job that much easier.

Cespedes tacked on a solo homer in the second, which extended the lead to 8-0 and almost matched the nine runs the A's scored in Gray's first three starts combined.

Just about everyone got in the act offensively for the A's on Friday. Reddick entered the game in a 1-for-17 slump and without any extra-base hits all season.

He changed his fortunes in a hurry with a homer and a single in his first two at-bats. He added a single in the seventh.

"I felt really good up there," Reddick said. "It's the best I felt since opening night. I just got to build off of it, come back tomorrow and hopefully do the same thing."

This was the kind of game that players off to slow starts such as Cespedes and Reddick might look back upon and point to as a turning point.

Cespedes raised his average from .213 to .246 and Reddick from .098 to .156 with 3 for 4 performances.

"Actually helping the team for once felt really good," Reddick said.

Friday's contest also provided the A's a much-welcomed breather from the kind of games that typified their recent nine-game road trip, where the final six games were decided by three runs or less.

The A's no doubt would like to use some of the runs they scored Friday for the remaining two games of the series.

Then again, it might not matter. The A's improved to 21-5 against the Astros all-time. Friday's result and recent history suggest the A's are primed to pile up wins like cordwood based on the fact they play the Astros six more times in the next nine days.

Gray surrendered three earned runs against the Astros, or one more than he allowed in his first three starts combined.

But he was sharp enough to make it through six innings to give Melvin the luxury of not taxing the bullpen.

"He continues to be good without probably seeing his best game to this point yet," Melvin said.

  • Leadoff hitter Crisp returned to the lineup after he was limited to pinch-hit appearances the past two games because of wrist and hamstring injuries. Craig Gentry pinch-hit for Crisp in the seventh.

  • There's something about the Astros that brings out the best in Cespedes, who banged out three hits and added a walk in his first four at-bats. He has hit safely in 13 straight games against the Astros, to the tune of .415 (22 for 53).

  • Even though the A's signed Doolittle to a long-term extension, that doesn't change Melvin's approach to how he uses his bullpen. Melvin said things are "status quo" for now, which means Doolittle or Luke Gregerson is going to be summoned for save situations, with erstwhile closer Jim Johnson the "wild card" in the equation.

    "Right now, we're fine with this, but there's the potential for anything," Melvin said.

  • Doolittle is now signed through the 2018 season with club options for 2019 and 2020.

    "It means everything that the organization thinks of you like that, that you're somebody that they want to keep around, they think that you can be a part of teams here for years to come," Doolittle said.

  • There isn't much new to report about the recovery by top prospect Addison Russell from his right hamstring injury.

    "It was probably a little more significant this time, a little higher up," Melvin said. "It may take him a little bit longer than when he came back during spring training."

    Russell first hurt his hamstring in early March. He damaged the same hamstring in early April while playing for Double-A Midland. The young shortstop is expected to be sidelined at least until May.
