Corey Seager will undergo Tommy John surgery and miss the remainder of the 2018 season, the Los Angeles Dodgers have announced.

Seager has a sprained ulnar collateral ligament in his right arm. He will have the surgery on Friday in Los Angeles.

"It's a big blow," Dave Roberts said. "We just feel for Corey. It's something that he's had to deal with for a couple of years. The elbow finally gave way and I feel bad for him."

Roberts said Chris Taylor would move in from the outfield to become L.A.'s everyday shortstop.
