The pitching matchup in this game is about as bad as you'll get between two veteran starters. Austin Gomber has a 6.42 ERA in eight road starts, 7.20 ERA in seven-night games, and a 10.67 ERA in his last seven starts overall. The Rockies bullpen is also the third-worst in MLB with a 4.75 ERA.
Arizona's bullpen is 24th with a 4.39 ERA, and they will be starting Dallas Keuchel was has an 8.27 ERA, and 2.10 WHIP in 10 starts this season. When these two pitchers faced each other last week in Colorado, the result was an 11-7 game. The venue is different this time, but 9.5 runs is a gift here.
