Escalona, who went 2-1 with a 2.93 ERA in 49 games with the Astros last year, injured his elbow swinging a bat last week. Mills said the lefty specialist feels the most pain when he throws his curveball and changeup and not as much on his fastball.
"We're going to give him a few days until it starts calming down," Mills said. "I don't know exactly [how long], but probably four or five days he'll be shut down, upwards to six days. He needs to start feeling better before he starts throwing and gets his arm strength back up to face hitters."
Meanwhile, third baseman Jimmy Paredes, who's nursing a sore left wrist, is taking batting practice left-handed, but is still not cleared to swing from the right side of the plate. It could be a few days before he sees any Grapefruit League action.
