Frias will start for Triple-A Oklahoma City on Sunday, David Vassegh of 570 AM LA Sports radio reports.

EDGE Analysis

After losing out on the No. 5 starter job to Ross Stripling in spring training, Frias reported to Oklahoma City, but he suffered an oblique injury before ever taking the mound in a game. The Dodgers sent him to Double-A Tulsa to knock some rust off after Frias was cleared to pitch -- have up just one run on three hits while striking out five over seven innings in his two starts for Tulsa. He could end up making a couple spot starts for the Dodgers down the road, but it's hard to imagine he'll claim a full-time rotation spot.
