Gsellman (5-6) landed in the loss column after allowing six runs (two earned) on nine hits and two walks in four innings Saturday against the Nationals. He struck out one and was optioned to Triple-A Las Vegas after the game.
While only two of the runs were earned, the other four runs came as a result of an error Gsellman committed in the first inning. He'll head back to the minors after compiling a 5.75 ERA and 59:31 K:BB through 87.2 innings as a big-league starter. He should be back with the Mets once rosters expand in September as a long reliever or a spot starter.
