The Washington Nationals are unsure if pitcher Ross Detwiler will be able to make his next scheduled start on Wednesday as he deals with a stiff lower back, according to Mark Zuckerman of CSN Washington.
The current stiffness is in a different location than an oblique injury that caused Detwiler to miss a month earlier in the season. Detwiler returned from that injury in mid-June and has made four starts since. Detwiler has made 12 starts this season, compiling a 4.13 ERA and 1.485 WHIP.
If Detwiler cannot make his start, Nationals manager Davey Johnson said he would start Ross Ohlendorf. Ohlendorf made a spot start for Washington on June 12, allowing two hits and a run over six innings against the Rockies. He has spent most of the 2012 season in the minors, posting a 4.27 ERA in 13 appearances, 12 of which were starts.
