Yes, I think the Padres are improved and a legitimate darkhorse. But I will fade them as road chalk at Coors Field. 
San Diego is 4-14 in its last 18 road games. 
The pitching matchup is Zach Davies versus Antonio Senzatela. I prefer Senzatela, who is 6-1 with a 3.30 ERA in 12 lifetime appearances versus the Padres, including six starts. He is 4-0 taking on the Padres at Coors Field. 
The Padres' late inning relief has been disappointing. The Rockies' relief staff has been surprisingly solid except for Wade Davis, who has no business being a closer anymore.
