Colorado has been an early surprise opening 4-1 with all five of those games on the road.
Now the Rockies are set for their home opener and they are in a great spot to win it. The price certainly is right to back them. 
The Rockies are throwing their ace, righty Jon Gray. The Rockies' bullpen has held up so far. Colorado has a 1.84 team ERA having faced the Rangers and A's. 
The Padres appear to be one of the most improved teams in baseball. But this is a bad spot for them. San Diego had to play late into the night on Thursday to defeat the Giants on the road in extra innings. Now they had to fly into Colorado. 
Colorado concluded last season winning seven of its last nine home games. They are tough to deal with at Coors Field especially if you lack experience at that ballpark. San Diego starter Garrett Richards has never pitched at Coors. He's likely in for a shock. 
San Diego has lost 12 of its last 15 road games when facing a righthanded starter and that includes its win Thursday against the weak Giants. The Padres are 1-4 in their last five games at Coors. They could be without steady first baseman Eric Hosmer, who has missed two straight games due to a stomach illness.
