With two wins over the Rangers in the series already, the Nationals face one of the stiffest tests yet. For the first time in his career, Yu Darvish faces the National. The right-hander, one of the best pitchers in baseball, has a 4-2 record with a 2.35 ERA this season. He finished second in the American League Cy Young voting last season, recording an absurd 11.9 K/9 rate last season. He has already struck out 71 batters in 61 1/3 inning this season. There’s another first on Sunday: Tanner Roark (3-3, 3.47 ERA) faces the team that traded him to Washington. The lineups are here. As always, talk about the game below.
