Bullpen catcher Murphy injured during batting practice
By Rick Eymer / Special to MLB.com
OAKLAND -- Houston bullpen catcher Jeff Murphy was an early casualty of batting practice Wednesday.
Murphy was throwing batting practice when a gust of wind knocked over the protection screen in front of the pitcher's mound.
Murphy got his left foot caught under the screen. He pulled himself free and tried to walk off the mound but fell to the ground, where he remained for a few minutes while teammates and coaches gathered around him.
Preliminary reports indicated Murphy suffered a pulled left hamstring and injured knee. He was in obvious pain as he was helped off the field and taken directly into the clubhouse.
Astros officials said the injuries weren't serious.
Sandbags were placed on the screen following the incident as 17 mile per hour winds swept through O.Co Coliseum.
Peacock takes cues from No. 1 starter Norris
OAKLAND -- Brad Peacock understands not everything will go according to plan, no matter how well prepared he is for any outcome.
That's why he's glad to have someone around like Wednesday's starter Bud Norris.
Norris suffered through a 12-game losing streak last year, and failed to get out of the first inning against the A's. But he was 4-1 in his five starts before that dating to last year.
"Bud helps me a lot every start," Peacock said. "Even between innings he goes over things and keeps me calmed down."
Peacock got himself out of a slight jam in the fourth inning of Tuesday's game and partly credited Norris.
"He told me when things get a little out of hand to take a walk around the mound until I'm ready to pitch again," Peacock said.
Houston manager Bo Porter said Peacock also learned something about holding runners after the A's stole a couple of easy bases.
"They did a good job of reading him," Porter said. "It's our job not to let that happen. We can't allow them to think we're robotic to the plate. We need to vary things."
• IF Jose Altuve singled to lead off Wednesday's game and has reached base in 14 of the Astros' first 15 games.
• DH Chris Carter drove in Altuve in the first and finished the nine-game road trip with nine RBIs.
• OF Fernando Martinez is 1-for-11 with two RBIs through his first three games of a rehab assignment with Oklahoma City. He started the season on the disabled list with a strained left oblique.
• RHP Asher Wojciechowski, pitching for Double-A Corpus Christi, has yet to allow an earned run in his first 14 innings, a span of three appearances, with 14 strikeouts.
• The Astros play host to the Cleveland Indians on Friday, their first non-AL West Division opponent.
