Former first round pick Erick Fedde was placed on the disabled list by the Single-A Potomac Nationals on Wednesday afternoon with mild oblique soreness. It's a small setback for the 23-year-old right-hander who had turned a corner lately after an uneven start to the 2016 season.

The 18th overall pick in the 2014 MLB Draft, Fedde has a 5.40 ERA in nine starts with Potomac. Before landing on the DL, he had tossed two consecutive scoreless outings with 11 strikeouts and just one walk during that span.

Fedde has made 23 starts in the Nationals minor league system since he was drafted. He has a 4.05 ERA with 105 strikeouts in 109 innings.

A UNLV-product, Fedde split his time during the 2015 season with the Auburn Doubledays of the New York-Penn League and the Single-A Hagerstown Suns.

Fedde is ranked by as the 72nd best MLB prospect overall and fourth in the Nationals system.
