Castro says K's come with Astros' approach

HOUSTON -- Catcher Jason Castro stopped short of characterizing the Astros as a "free-swinging" team, but at the same time, he acknowledged that they don't get cheated at the plate, either.

On Friday, the Astros broke the Tigers' pitching staff's seven-game streak of striking out at least 10 batters in a game -- an American League record. Still, the Astros have struck out a Major League-leading 300 times in 30 games this season, including 18 in Thursday's 14-inning loss.

"Part of our approach is trying to be what we call 'selectively aggressive,'" Castro said. "So we're trying to find pitches in the zone that we're able to drive and put aggressive swings on them.

"We have some guys with big-time power on this team. So that's part of their game. So you will see guys taking some pretty big hacks. And we have guys that are capable of hitting it out of the ballpark on any given at-bat. So I think that's part of it."

It's of little concern, therefore, that the Astros are striking out 10 times per game on average.

"It's part of the game," Castro said of the whiffs. "I don't think we're striking out at an alarming rate. And we've been competitive. I think we're right on the edge of kind of tipping the scales in our favor. It's just a matter of time before things start clicking for us."

Corporan gets back-to-back starts behind the plate

HOUSTON -- Carlos Corporan was behind the plate again for the Astros on Saturday for his second consecutive start. But it isn't only because Lucas Harrell is the starting pitcher.

"I've been catching Lucas Harrell, we feel comfortable with each other," Corporan said. "Every time they put me in the lineup, I try to give 100 percent."

"It was more designed to get Corporan back-to-back [starts]," Astros manager Bo Porter said. "After the long flight home, the 14-inning game; [Jason] Castro has been outstanding, but at the same time, I want to do everything that I can to keep him fresh throughout the course of the year."

Porter added that Castro would be back behind the plate for Sunday's series finale against the Tigers. Monday is an off-day.

"So it's like [Castro] is getting three days off in a five-day span, which is great," Porter said.

Cedeno given chance to face a righty starter

HOUSTON -- He won't see a left-handed starter, but Ronny Cedeno was back in the lineup on Saturday.

The Astros' shortstop is hitting .455 (10-for-22) against lefties and .167 (3-for-18) against righties entering Saturday, but Astros manager Bo Porter penciled him into Saturday's lineup against Detroit right-hander Max Scherzer.

"With the slate of righties in which we have going, he's been playing well and I don't want him to sit too long without getting a start," Porter said. "He's got decent numbers against [Scherzer]."

Cedeno is 3-for-4 lifetime against Scherzer, with two RBIs.
