Reds’ right-handed reliever Drew Storen will undergo Tommy John surgery, according to a report from the Cincinnati Enquirer’s C. Trent Rosecrans. Storen was placed on the 10-day disabled list last Wednesday with a right elbow sprain, but has not appeared in a game since September 1. The Reds tried resting their reliever for a week before deciding to place him on the DL, but it appears that little progress has been made with either approach. A timeline for Storen’s return has not been released, though it’s safe to assume that he’ll miss the entire 2018 season during his recovery.

Storen, 30, is in his first run with the Reds. He finished the season with a 4.45 ERA, 3.8 BB/9 and 7.2 SO/9 in 54 2/3 innings that more accurately reflects a disappointing second half performance than the dominant stretch of 2.80-ERA ball he delivered in the first half.
