"We think the role he's capable of playing in the bullpen as a key lefty for us probably takes precedent at this point in his career," Wade said. "It doesn't mean at some point he's not going to be a very successful starter, but for the time being, we're going to focus on him as a reliever."
Abad, who posted a 2.84 ERA in 22 games in relief in his Major League debut last year, started 10 games in the Dominican Winter League and was 3-1 with a 3.42 ERA. That forced the Astros to discuss putting him in the mix for a spot in the rotation.
With Abad out of the picture, those competing for the fifth spot in the rotation are Nelson Figueroa, Ryan Rowland-Smith, Jordan Lyles, Aneury Rodriguez and Lance Pendleton.
