Rainey (1-2) allowed two hits and a walk while striking out one in two-thirds of an inning, earning the win in Wednesday's 13-12 win over the Phillies.
The righty also had a blown save by letting both inherited runners score in the eighth inning. With the two outs, Rainey lowered his ERA to a still-alarming 7.54, though seven of his last eight appearances have been scoreless and he remains the second most-trusted option in the Nationals' bullpen while Daniel Hudson (elbow) is out.
