The Colorado Rockies claimed their spot in the National League Division Series after winning a marathon wild card game 2-1 against the Chicago Cubs.

Despite taking an early lead at Wrigley Field, the Rockies had to face 13 innings before claiming a 2-1 win in the longest winner-takes-all post-season game in MLB history.

Colorado had opened the scoring in the first, after Nolan Arenado’s hit allowed Charlie Blackmon to get home from third base, but Javier Baez tied the game with an RBI double in the eighth.

From there, both teams struggled to edge ahead until Tony Wolters hit a tie-breaking single with two outs in the 13th.

The Rockies now head to Milwaukee for game one of the best-of-five division series against the NL Central champions the Brewers on Thursday.

It is the first time the Rockies have reached the division series since 2009.
