"If Tyler gets into a game, whether it's today, tomorrow or the next day, I think he's ready to make a contribution," Rockies manager Bud Black said. "He's ready to get his outs, and I think his pitch mix is fine. He feels good about his velocity and he feels good about his second pitches. He'll help us."
The 27-year-old former first-round pick made his last rehab outing with Albuquerque on Monday and threw 50 pitches over 3 1/3 innings, allowing a run on three hits. It was his third rehab outing since having surgery.
"The outing in Albuquerque -- his last one -- he got to a pitch count where he was comfortable," Black said. "He wasn't quite as crisp as he was his previous rehab outing, but Tyler is ready.
"With Tyler, you're getting a guy with that relaxed intensity that we talk about."
Anderson is 3-5 with a 6.11 ERA over 13 appearances (12 starts) this season. He figures to slot into the team's bullpen for the rest of the season. With Black expecting bullpen games every fifth day for the Rockies, Anderson may be used prominently on those occasions.
Black said there was a chance Anderson would pitch Sunday. Anderson's relief outing this year was his first in the Majors.
Diaz, 26, was placed on the seven-day disabled list at Albuquerque retroactive to Aug. 14 with right elbow inflammation and hasn't pitched since. He's made two stints with the Rockies this year and allowed six runs (five earned) on 12 hits over five innings.
• Black elected to bat the pitcher's spot eighth Sunday, which has been a rare occasion this season. He chose to make the move with starter Tyler Chatwood only expected to throw 60 to 70 pitches before turning to the bullpen.
"It gives us an option there a spot earlier to maybe pinch-hit a guy for Chatwood," Black said. "And as we move forward in the game, just a spot a little sooner for a guy to come off the bench and be a little more offensive.
• The Rockies' win Saturday gave them their first three-game winning streak at Dodger Stadium in a single season since 2008, when they won four in a row. They've swept the Dodgers in a four-game series twice in franchise history (1993, 2007).
