WASHINGTON (AP) – Stephen Strasburg won his 12th consecutive decision dating to last season and Jayson Werth connected for a pinch-hit grand slam to help the Washington Nationals close out the season series against the St. Louis Cardinals with a 10-2 win on Sunday.

Wilson Ramos had three hits, including a two-run homer, and drove in four runs. Bryce Harper hit an RBI single during Washington’s three-run fourth inning off Michael Wacha (2-6). Strasburg (9-0) pitched six innings of one-run ball as Washington salvaged a split of the four-game series. The right-hander improved to 12-0 in 15 starts since losing to the Mets on Sept. 9, and the Nationals have won all 15 of those games.

The Cardinals will take on the Milwaukee Brewers Monday afternoon for the first of a three-game set. Pre-game coverage begins at 12:15, here on KJAN. The first pitch is at 1:10.
