The Nationals signed right-hander Ross Ohlendorf to a minor league contract, Matt Eddy of Baseball America reports (on Twitter). Williams & Connolly represents Ohlendorf.
The 30-year-old pitched 48 2/3 innings for the 2012 Padres, but posted a 7.77 ERA. He started nine games for San Diego and appeared in four more as a reliever, posting 7.2 K/9 and 3.3 BB/9. Ohlendorf was a fixture in the Pirates' rotation from 2009-10, but Pittsburgh released him in December of 2011.
