ST. LOUIS (AP) — Pinch hitter Tyler Moore blooped a two-out, two-run single in the eighth inning and the Washington Nationals won in their postseason debut, beating the defending World Series champion St. Louis Cardinals in 3-2 Sunday in an NL playoff opener. The Nationals overcame a wild start by 21-game winner Gio Gonzalez, then watched their bullpen shut down St. Louis in the late innings. Ahead 2-1 in the seventh, the Cardinals didn’t score after loading the bases with no outs.
