Clint Barmes is not in the Pirates' starting lineup Wednesday against the Nationals. Barmes went 0-for-3 with a strikeout on Tuesday and is now hitting just .159/.196/.307 across 94 plate appearances, so he could probably use the breather. Josh Harrison will start in his place at shortstop Wednesday and bat eighth against left-hander Ross Detwiler. Rod Barajas, who hit a walkoff homer Tuesday, slides up to the seventh spot.
