The Phillies entered the day with a magic number of one to clinch the division - a bit of a disappointment after a 2-5 road trip against the Milwaukee Brewers and New York Mets.
However, some home cooking proved to be the right recipe for Philadelphia (93-64), which remains a half-game behind the Los Angeles Dodgers in the race for the best record in the NL.
Realmuto, Schwarber, Bryce Harper and Nick Castellanos each finished with two hits for the Phillies. Nola (13-8) allowed two runs on seven hits in six-plus frames. He walked two and struck out seven to earn his first victory since August 27th.
Isaac Paredes registered a pair of hits for the Cubs, who had won three of their previous four games.

Mariners 6 Astros 1
Bryce Miller stymied host Houston by logging seven scoreless innings as Seattle gained ground in the American League playoff race.
Jorge Polanco, Julio Rodriguez and Randy Arozarena each had an RBI double for the Mariners, who closed within 1 1/2 games of the final AL wild-card spot. Miller (12-8) scattered two hits and two walks while striking out five, including consecutive punchouts with runners on second and third in the seventh inning.
Hunter Brown (11-9) was just as stingy as Miller over his six innings for the Astros, who would have clinched their fourth straight AL West title with a win Monday. The right-hander limited the Mariners to one run on three hits and three walks while fanning eight.
