Nationals 2, Twins 0
WASHINGTON — Tanner Roark struck out a career-high 15 and allowed only two hits over seven in a dominating performance that carried the Nationals. Roark and a trio of relievers combined to fan 18, the most by Washington since its arrival from Montreal in 2005. Jonathan Papelbon got three outs to complete the combined two-hitter and earn his seventh save. Ryan Zimmerman drove in two and Bryce Harper had a pair of doubles for the Nationals, whose 13-4 start is best in franchise history.
