The Washington Nationals attempt to complete a sweep of their brief two-game interleague series when they host the Houston Astros on Wednesday. Washington snapped its four-game losing streak with a 6-5 triumph in Tuesday's opener as Anthony Rendon recorded two doubles and three RBIs while Ryan Zimmerman added two of each. The six runs seemed like an offensive explosion for the Nationals after they registered a total of four during their slide.The loss was the third in four games for the Astros, who staged a four-run rally in the eighth inning but came up just short. Jose Altuve was a force at the plate, collecting a season-high four hits - including a two-run double that capped the late uprising. Altuve, who was held out of Houston's starting lineup in each of the previous three games due to a hand injury, has recorded multiple hits in three of his last five contests.TV: 7:05 p.m. ET, CSN (Houston), MASN (Washington)PITCHING MATCHUP: Astros RH Scott Feldman (3-4, 3.98 ERA) vs. Nationals LH Gio Gonzalez (3-4, 4.62)Feldman's winless streak reached three starts Thursday as he received a no-decision against Arizona after allowing three runs - two earned - in 6 1/3 innings.
