SCOTTSDALE, Ariz. -- The D-backs are down to two open spots in their rotation after manager Chip Hale said Tuesday that right-hander Rubby De La Rosa had done enough to earn a spot, joining Opening Day starter Josh Collmenter and Jeremy Hellickson.
De La Rosa, who joined the D-backs in the December trade that sent Wade Miley to the Red Sox, has a 3.75 ERA in four Cactus League games, and he threw 5 2/3 innings in a Minor League exhibition on Tuesday, allowing two runs on five hits.
"I think he's one of our five starters, yes," Hale said. "I think Rubby's proven enough to us. Like I said, there's two weeks left. Right now, he's one of our five. He's a difference-maker, being a power guy in our rotation with Hellickson and Collmenter being more of the finesse-type pitchers. He's a nice mix in there, so I feel good about him starting for us."
Control has been an issue for De La Rosa this spring. In four Cactus League games, he has allowed 10 walks over 12 innings. In Tuesday's Minor League game he walked a pair.
As for the final spots in the rotation, Hale said that any pitcher left in camp is still in the mix, but the front-runners figure to be Daniel Hudson, Chase Anderson and Trevor Cahill.
