Frias (back) expects to return to the rotation shortly after the All-Star break, MLB.com's Ken Gurnick reports. Frias was placed on the 15-day DL Sunday, but the back soreness that landed him there isn't expected to have long-term consequences. He had experienced this issue during his previous three starts, and with the All-Star break around the corner, it was finally time to deal with it. After a bit of extra rest, he'll make one rehab start before reclaiming his back-end rotation spot.
