Gsellman stymied the Nationals for the second time in less than two weeks, throwing 5.2 innings of shut out ball Wednesday.
Gsellman allowed one run in six innings on September 3 to defeat Washington. Wednesday, he allowed five hits and a walk with four strikeouts in his scoreless outing. Gsellman left the game with a runner in and two outs, who was stranded when Josh Smoker struck out Bryce Harper. He now has a 3.08 ERA in 26.1 innings and likely will remain in the rotation, even with the possible returns of Jacob deGrom and Steven Matz.
