Derek Holland pitched two scoreless innings for Triple-A Round Rock Friday in the first start of what he hopes is an accelerated rehab stint.

Holland is hoping to make just three starts and return to the roster on Aug. 20, the first day he's eligible to come off the 60-day DL.

Holland walked the first batter of the game, then retired the next three hitters. After a one-out single and a fielding error in the second, he got a double-play grounder to finish his night with 28 pitches. He had been scheduled to go two innings or about 30 pitches. If he pitches every fifth day and builds up 15-20 pitches per start, Holland could have as many 70 pitches in an outing in time for Aug. 20. It might give him the chance to get through five innings at that point.

"I don't know if it will be the same kind of buildup as you'd have in a spring training situation," Rangers manager Jeff Banister said. "We'll see how he feels and executes and we'll go from there. We'll be as aggressive on him as his arm allows us to be."

Meanwhile, right-hander Colby Lewis is hoping to throw off a mound to a catcher standing in front of the plate before the end of the road trip. He is scheduled for another scan on his lat muscle when the Rangers return home and then could get a go-ahead to begin full-scale bullpen work. Lewis is at least 10 days behind Holland.

Lewis said the Rangers-Astros series outcome over the weekend might have an impact on the Rangers' plans

"I think these three games could dictate a little about how aggressive we are in getting me back," Lewis said.
