After two days off, Altuve in Saturday's lineup

MINNEAPOLIS -- The Astros' starting lineup looks a whole lot better with Jose Altuve in it.

Altuve rejoined the lineup on Saturday against the Twins after missing the previous two games with a sore left quadriceps muscle. He entered the game hitting .284 with four homers and 34 RBIs and was third in the American League with 26 stolen bases.

"You never want him to come out of the lineup, but at the same time, you don't want him to risk having something that will linger for a longer period of time," manager Bo Porter said. "[Head athletic trainer] Nate [Lucero] brought him out today, and he was able to do all the running they wanted him to do, and he came in and said, 'I think he's fine.'"

The Astros were 1-8 in games in which Altuve didn't start at second base or designated hitter.

"Put it like this -- I want the only time he's not in the lineup is if I choose to give him a day," Porter said. "He's a guy that if he can play all 162, he'll play all 162. At the same time, there have been times this year I have picked a day to give him a day with an off-day coming up the next day, so he has two days to recover. He is that kind of guy who's in the lineup every day, and it doesn't matter who's pitching for the other team."

Porter urges team to pay attention to details

MINNEAPOLIS -- Astros manager Bo Porter has spoken more than once about the 2013 season being a learning experience for his team, which is the youngest in the Majors. And the learning just doesn't take place on the field.

Porter has stressed to his players to not only learn from their own mistakes, but other people's mistakes as well.

"Watch the other team's players, watch the game," he said.

Porter says players nowadays grew up in a "SportsCenter generation," meaning they were fed highlights of baseball games, but didn't always get to see the work that went into the success.

"When I was coming up, you literally had to watch the game to find out what happened," he said. "Now, you see a guy hit a home run, but they don't show you the 1-2 breaking ball he took, the 2-2 changeup he took to get himself to the 3-2 pitch to hit the home run."

Porter has urged players to pay more attention to the details in their pursuit of success.

"Watch the game in its entirety, see what's going on, and you'll be amazed how you can learn and not wait for someone else to teach it to you," he said.

Astros tab righty Peacock for series finale

MINNEAPOLIS -- Right-hander Brad Peacock, who has been putting up terrific numbers at Triple-A, was recalled after Saturday's 6-4 loss to the Twins to make the start in Sunday's game at Target Field. To make room for him, Jimmy Paredes was optioned to Oklahoma City.

The Astros were forced to find a starter for the series finale after Dallas Keuchel came out of the bullpen and worked 1 2/3 innings in a 13-inning loss to the Twins on Saturday. Peacock, who won't be officially added to the roster until Sunday, is 6-2 with a 2.73 ERA in 14 games (13 starts) with the RedHawks.

"He's thrown the ball extremely well," Astros manager Bo Porter said. "That's obviously factored into the decision-making."

Peacock, 25, began the year in the Astros' rotation and went 1-3 with an 8.44 ERA in five starts before being moved to the bullpen, where he posted a 7.04 ERA in four appearances (7 2/3 innings). Porter said it's "definitely a possibility" that Peacock could remain in the rotation.

The Astros have had to shuffle their rotation quite a bit in recent days. Lucas Harrell started in place of Bud Norris on Tuesday prior to the Trade Deadline, and Brett Oberholtzer took Erik Bedard's place Wednesday when he was pushed back with shoulder soreness.

The team has set its rotation for next week's series against the Red Sox: Oberholtzer on Monday, Jordan Lyles on Tuesday and Jarred Cosart on Wednesday.
