Nationals 8, Diamondbacks 1: Stephen Strasburg scattered three hits over eight dominant innings and Ian Desmond went 3-for-4 with four RBIs while recording his 100th career stolen base as host Washington extended its season-best winning streak to eight games.

Asdrubal Cabrera drove in three runs and Jayson Werth collected three hits and an RBI for the Nationals, who maintained their six-game lead over second-place Atlanta in the National League East. Strasburg (10-10) yielded one run and walked one while striking out four en route to his third win in four starts, a stretch during which he has given up two runs - one earned - and nine hits with 22 strikeouts over 22 innings in the victories.

David Peralta homered for the Diamondbacks, who fell to 2-6 on their 10-game road trip. Chase Anderson (7-5) was tagged for six runs on six hits and three walks in two-plus frames as his six-start unbeaten streak came to an end.

Arizona took an early lead as Peralta deposited a 2-2 offering from Strasburg over the right-center field wall with two outs in the first inning, but Washington erupted in the third to grab control. Denard Span ignited the rally with a leadoff single and stole second before scoring on Werth's base hit two batters later to forge a tie.

Anderson walked Adam LaRoche to load the bases and Desmond followed with a two-run single to left field. Bryce Harper's base hit chased Anderson and reloaded the bags for Cabrera, who greeted Eury De La Rosa with a three-run double to cap the outburst, and Desmond added another two-run single in the sixth for an 8-1 advantage.
