Guthrie could make a spot start for the Nationals on Sunday against the Phillies, Jorge Castillo of The Washington Post reports.

EDGE Analysis

Joe Ross was originally thought to be in line for that start, but after being optioned to Triple-A Syracuse the 23-year-old must remain in the minors for at least 10 days. If Guthrie does get the call his stay in the majors will likely be a brief one, but the Nats could also shuffle their pitching staff to keep the veteran around as a long reliever, something they don't currently have on their roster.
