Perez gave up two hits, including a solo home run, in two-thirds of an inning Wednesday to record his first hold of the season in an extra-inning loss to the Phillies.
The 29-year-old lefty entered the game with two outs in the seventh inning and retired Kyle Schwarber, but Bryce Harper then took Perez deep to lead off the eighth as the Nationals' bullpen squandered a 5-0 lead. Perez may not hang onto a high-leverage role much longer if he can't keep the ball in the park -- he's served up two homers in his first three appearances and 2.2 innings this season, although his 3:0 K:BB is more promising than his 6.75 ERA.
