Couple of things here. First, why do the Dbacks have to sweep Colorado. They are 4 in back of the Phillies and have the tie breaker with them. If they win 2 of 3, and the Phillies lose 2 of 3 from the Brewers, at least the first game against SD matters. Next, why can’t Arizona seeep the Rockies, who are 32-46 at home? They aren’t exactly a juggernaut at home. Sure, Az pitchers may be wearing down, but Colorado has to pitch too. Sure, it may not happen. But I wouldn’t say I can’t see the Dbacks gaining one game in the next 3 is unrealistic considering they play Colorado and the Phillies play the Brewers. In fact, if they do sweep the Rockies there is a chance they could be 3 back of SD, who could easily lose 2 of 3 in LA. That is a bigger reach, however.
