"I'm hoping he throws up a gem against a very tough lineup," manager Dusty Baker said Saturday.
The Nationals' starting rotation has been hampered by injures to Joe Ross, who has been out with right shoulder inflammation since early July, and Stephen Strasburg, who has missed two starts since being placed on the disabled list with right elbow soreness. Rookies Giolito, Reynaldo Lopez and A.J. Cole have combined to fill in for the injured hurlers, with mixed results.
Difo hit .257/.297/.314 in 37 plate appearances for the Nats this season while filling in at shortstop, second base and third base. He will likely be recalled once rosters expand on Sept. 1.
