Cahill to face rookies in next stage of rehab

PHOENIX -- Entering his fourth week on the disabled list, D-backs right-hander Trevor Cahill's path back to the club's starting rotation is beginning to become clear. The 25-year-old threw a bullpen session Tuesday and will start for the Arizona League (Rookie) D-backs on Thursday against the Angels.

If that outing goes well, Cahill will progress to the final step of his rehab, a Minor League assignment.

"He feels good, feeling stronger," D-backs manager Kirk Gibson said. "His mechanics are better and he's pain free."

Cahill, whose rehab was slowed by shoulder soreness a couple of weeks ago, has been sidelined since July 1 with a right hip contusion. Before the injury, he was 3-10 with a 4.66 ERA in 17 starts. He'll throw between 60-70 pitches Thursday.
