CHICAGO -- - Pete Crow-Armstrong hit a two-run shot to become the first Cubs player with 30 homers, 30 doubles and 30 stolen bases in a season, Seiya Suzuki iced the game with a grand slam and Chicago pounded the St. Cardinals 12-1 on Friday to close in on the top National League wild card.

Michael Busch hit his team-leading 32nd homer and had two RBI as the playoff-bound Cubs won for just the second time in eight games and trimmed their magic number to one for securing home-field advantage in their opening-round playoff series against San Diego. Game 1 of that series is Tuesday.

Suzuki's second career grand slam, capping Chicago's seven-run seventh, made him the third Cub with 30 homers this season. Nico Hoerner also went deep.

Colin Rea (11-7) allowed two hits in 5 2/3 score
