Jesse Crain (biceps) will continue his rehab in Florida and could throw off a mound as early as Tuesday.

The Astros signed the right-hander this winter with the understanding that Crain wouldn't be ready for the start of the season.

Crain suffered a strained right calf last week, but it's his recovery from offseason biceps surgery that remains the bigger issue. The reliever will begin the season on the disabled list. "The calf's getting a lot better," he said. "I should be out and hopefully running within the next week. The good thing is if I was on the mound throwing and getting ready for the season and this happened, it would be a setback. As far as where I am with my throwing program, it didn't affect any of that."
