Guthrie will start Saturday for the Nationals as expected, Dan Kolko of MASN reports.

EDGE Analysis

Guthrie remains on the Triple-A roster for now, but a roster move will be coming before Saturday's 7:05 PM start time. His spot on the roster is likely to be short-lived. The Nationals can't use Joe Ross for this start because he was optioned fewer than 10 days ago. Unless Guthrie really shuts down Philadelphia on Saturday, Ross will likely be the Nationals' long-term fifth starter.
