The Pittsburgh Pirates made a roster move on Wednesday before their matchup with the Washington Nationals, sending outfielder Alex Presley to triple-a and recalled right-handed pitcher Evan Meek, according to Rob Biertempfel.

With Brad Lincoln's spot start, the Bucs would have been operating with a short bullpen so they needed another reliever for a few games. The belief is also that the Pirates will send Meek back down in favor of catcher Jake Fox for the Bucs interleague series against the Detroit Tigers.
Presely had struggled while in the lineup as an outfield, so his demotion shouldn't come as too much of a surprise.
