Trainers err on side of caution as Ambriz rolls ankle

KISSIMMEE, Fla. -- The Astros saw their second minor injury of the spring when relief pitcher Hector Ambriz rolled his ankle during a drill. He was removed from the field to be examined by trainers and have the ankle taped.

"It's minor, but at the same time, we want to be careful this time of year," manager Bo Porter said. "They said it's a little tender, a little sore. He'll get treatment, and we'll re-evaluate him [Friday]."

Meanwhile, catcher Max Stassi, acquired in last week's trade with Oakland, was held out of drills for the second day in a row because of a strained oblique.

"We just want to be careful," Porter said. "He comes over here from Oakland, and it's something we knew about, but at the same time, it's too early in the spring to even push it. We're not close to playing games, and it allows us to get this thing healed so when he does get back on the field, he's ready to go."
