HOUSTON -- Though no one had told him officially, Oakland's Dan Straily knew after Friday night's start he'd be sent down to Triple-A.
The rookie didn't let that bother him, allowing five hits and striking out a career-high 11 in 6 2-3 solid innings of an 8-3 win over the Houston Astros.

Straily (1-0) was sent down to make room on the roster for Bartolo Colon, who will face the A's Saturday in his first start since receiving a 50-game suspension for a positive testosterone test last Aug. 22.
"It was something I've thought about," Straily said moments after receiving the news. "I kept trying not to, but I can do basic math, there's six of us for five spots. I'm the least experienced and youngest guy, so I just take it in stride."
Manager Bob Melvin was impressed with Straily's work.
"That might have been the best we've seen him pitch," Melvin said. "A strong performance for a guy that obviously we just sent down and had that weighing on his mind going out to pitch, too. So that was doubly impressive to give us that kind of outing."
Coco Crisp hit a leadoff homer and added two doubles in Oakland's big fifth inning to back Straily.
Crisp sent the fourth pitch of the night over the wall in the corner of right field for his ninth career leadoff homer.
The Athletics were up 1-0 when Crisp doubled with one out in the fifth to chase Houston starter Brad Peacock (0-1). His second double of the inning drove in two runs in Oakland's seven-run outburst.
"It's a little shocking when you hit around," Crisp said. "It doesn't happen that often in the big leagues or just period -- Little League. It's always exciting as a team when that happens."
Crisp was dealing with a tight back Friday night after attempting to make a diving catch in the bottom of the first inning.
"It kind of loosened up as the game went on," he said. "They were thinking about taking me out ... but I just got some work done on it throughout the course of the game and I was OK."
He iced it after the game and thinks he'll be fine to play on Saturday.
Josh Donaldson added a two-run single in that inning as the Athletics visited the Astros for just the second time and the first since 2007.
They'll get plenty acquainted with Minute Maid Park this season. Oakland makes two more trips to Houston with the Astros joining the AL West.
Houston set a major league record for the most strikeouts in the first three games of the season with 43.
This team, which has the league's lowest payroll and is coming off consecutive 100-loss seasons, continued its torrid strikeout pace Friday by adding 13. Each of the four starters the Astros have faced this season have either set or tied career highs in strikeouts.
Straily is the first Oakland pitcher to strike out 11 since Gio Gonzalez did it on Sept. 28, 2011.
"In the major leagues you're going to get at least one pitch to hit, and when you get it you've got to put it in play hard," Houston manager Bo Porter said. "And if you don't put it in play hard you're going to find yourself chasing the pitcher's pitch, and that's what happened tonight."
Straily allowed a single to Chris Carter with two outs in the first inning before retiring 13 of the next 14 batters. Houston's next hit came when Marwin Gonzalez doubled down the right field line to start Houston's sixth. The Astros scored for the first time in 24 1-3 innings when Jose Altuve drove in Gonzalez with a single to make it 8-1.
Justin Maxwell doubled off Straily with no outs in the seventh. He was replaced by Pat Neshek, who allowed an RBI single to Matt Dominguez.
Peacock allowed three hits and two runs with five strikeouts in 4 1-3 innings in his first major league appearance since 2011. It was his debut with the Astros after being traded from the Athletics with Carter for Jed Lowrie just before spring training.
Peacock, who spent last season in Triple-A, had retired eight in a row before he was chased by Crisp's double with one out in the fifth inning.
"It was the first time I'd been out there in a while," Peacock said. "I wasn't nervous, but I was over-amped, trying to throw a little too hard, maybe."
He was replaced by Xavier Cedeno, who struggled with command from the beginning. He walked the first two batters he faced to load the bases before an error by shortstop Gonzalez allowed Yoenis Cespedes to reach and two runs scored.
A sacrifice bunt by John Jaso drove home another run before Chris Young walked to load the bases again. Donaldson singled in a pair of runs on a line drive to right field to push the lead to 6-0.
Cedeno then plunked Eric Sogard before being replaced by Rhiner Cruz without recording an out.
Cruz retired one batter before Crisp hit his second double of the inning, this one to drive in two runs and make it 8-0.
Lowrie walked before the Astros finally got out of that inning when Maxwell grabbed a long fly from Josh Reddick, the 13th batter of the inning.
