"Probably skipping a little more than one start," D-backs manager Chip Hale said. "We're looking at next week on the road we're going to start him. But he's in the bullpen right now. I think maybe Chase needed a little break. He's been working with [pitching coach Mike Harkey] on some fundamental stuff and getting the ball down and all that stuff. But of course, you're not going to see that unless you pitch in a game. So we're going to try to get him in some games out of the bullpen."
Jhoulys Chacin, who will start Tuesday's game against the Padres, essentially is taking Anderson's spot this time through the rotation.
Meanwhile, the D-backs do not like the way De La Rosa matches up with the Dodgers. In four starts against them this year, he has an 11.21 ERA.
De La Rosa's next start is Friday in San Francisco and after that he would have faced the Dodgers in Los Angeles, but he may have that start skipped.
