Cubs clinch playoff spot, Pirates win on Stallings HR in 9th
The NL Central-leading Cubs were assured a spot in the expanded playoff field when Philadelphia was swept in a doubleheader at Washington. It was Stallings’ third home run of the season and the third game-ending hit of his career. Anthony Rizzo’s two-run homer in the eighth inning had pulled the Cubs into a tie at 2-all. The Pirates took a 2-0 lead on RBI doubles by Erik Gonzalez in the second inning and Adam Frazier in the fifth. Pirates: RHP Trevor Williams (1-8, 6.70) has lost five straight decisions since getting his lone win Aug. 13 at Cincinnati.
