After a bullpen meltdown that led to a 5-2 loss on Tuesday, the Rockies will look to rebound and keep their playoff hopes alive. They are currently three games out of the eight seed, but the Giants are tied with the Brewers. These next two games are critical for the Rockies playoff hopes.
Ryan Castellani (1-3, 5.59 ERA) will take the mound for the Rockies. In his last outing against the Dodgers on September 18, he got roughed up for eight runs (seven earned) in 4 1⁄3 innings.
