Wojciechowski taking two-week break from throwing

HOUSTON -- Right-hander Asher Wojciechowski, the Astros' No. 13 prospect, was sent back to club's Spring Training home in Kissimmee, Fla., to continue his rehab after suffering a flexor muscle strain.

The injury that sent Wojciechowski to the disabled list was a right lat strain he suffered on Feb. 1. While the injury has been slow to heal, Wojciechowski was making progress, throwing four innings in a Triple-A Oklahoma City rehab assignment and only giving up one run and four hits.

"It's nothing too severe," general manager Jeff Luhnow said. "We don't think there's any real issue, but he's not going to throw in a game for the next two weeks. He's going to go to Florida and do some rehab and throw down there."

Wojciechowski had an ERA of 3.56 with 104 strikeouts and 44 walks for Triple-A Oklahoma City in 2013.

McHugh ends outing with highlight-reel snag

HOUSTON -- Somehow, Collin McHugh said, he's good for one of them per year.

Albert Pujols scorched his 86-mph pitch back up the middle, bouncing off the ground before it got to the pitcher's mound. McHugh's reaction was to stick his glove out -- behind his back.

The sound and the feeling that followed were familiar.

"I've done it enough times to where it hits, and you're like, 'That's in there,'" McHugh said after the Astros' 7-2 victory over the Angels.

McHugh looked at the ball in his glove after making the behind-the-back catch, took a few steps toward first base and tossed the ball to Jon Singleton for the fifth inning's final out.

"Anything that's hit back up the middle, I'm going to try to throw my glove at and see what happens," McHugh said. "It's totally luck. Albert knew it, too."

Porter slides Fowler back into leadoff spot

HOUSTON -- With the addition of Jon Singleton, the Astros changed the top of their order for Tuesday night's game against the Angels.

Dexter Fowler, who has been hitting third, moved back to the leadoff spot, which was his original role with the Astros at the beginning of the season. The club moved Jose Altuve, who leads the Major Leagues with 78 hits, to second and George Springer, the American League Rookie of the Month Award winner, to third.

"It's the same game, it's the same guys," Springer said. "The goal is to get them on, get them over and hit them in."

Manager Bo Porter said the addition of Singleton allowed the lineup change. Porter had two goals with the switch. The first, he said, was to get Fowler back in the leadoff spot. Fowler leads the Astros with an on-base percentage of .366. The second was to keep Altuve hitting in front of Springer.

"Now you start to get length throughout the lineup," Porter said. "Those six guys we have at the top give us the best chance to have length in our lineup."
