Homer Bailey will undergo surgery Friday on his right forearm to repair a flexor mass tendon tear, the Cincinnati Reds have announced.

The right-hander is expected to be ready in time for Spring Training.

Bailey signed a six-year, $104 million extension with the Reds before the season. He posted a 3.71 ERA, 1.229 WHIP and 124 strikeouts in 145.2 innings.
