Ian Happ hit a game-ending single in the 10th inning, and the Chicago Cubs edged the Pittsburgh Pirates 3-2 on Sunday.

One of baseball's best run-scoring teams, the Cubs won three out of four this weekend, doing so while scoring only nine runs in the series.

While both teams have trended towards the Under across their last 10 games, a larger sample size suggests the Cubs are a run machine. The hosts sit second in the majors with 382 runs, and only the Los Angeles Dodgers and Boston Red Sox have served up more hits.
