Williams asked Moore if he could pitch and throw strikes. Moore said he could. Williams decided he wasn't going to use anymore relievers with the game out of reach.
Prior to Wednesday's game, the last time Moore pitched was when he attended Northwest Rankin High School in Flowood, Miss. Lobaton asked Moore about his pitching repertoire.
"He said he had a fastball and curveball," Lobaton said. "I just told him, 'Throw strikes.'"
Moore pitched two-thirds of an inning without allowing a run or a hit, though he did allow an inherited runner to score. There were runners on first and third when Moore entered the game. He induced Paul Goldschmidt to ground into a force play, which scored Ender Inciarte. After Moore hit Welington Castillo with a pitch, Aaron Hill lined out to second baseman Anthony Rendon to end the inning.
Moore became the second position player to pitch for the Nationals since the franchise moved from Montreal to Washington in 2005. Clint Robinson was the first position player to pitch for Washington, and he also did it against the D-backs back on May 13 in Arizona.
Asked how his arm felt after the game, Moore said, "It feels good. It kind of stinks after a loss. The bullpen has been taking some heat here lately, and I was able to get a couple of outs, so that was good for us."
