Stallings had a game-winning RBI single as a pinch hitter in the 11th inning in Friday's 6-5 victory over the Nationals.
Recalled from Triple-A Indianapolis on Sept. 13, Stallings came through with the game-winning hit in what was his first at-bat since returning to the big league club. The 22-year-old has slashed .222/.222/.333 in a scant nine major league at-bats in 2016 and is essentially on the roster to serve as the third catcher for the balance of the campaign.
