The Arizona Dbacks lost their first series of the season. They lost 2 out of 3 games to the Colorado Rockies at Chase Field. It's just 3 out of 182 games, but should the Dbacks started to worry?
They picked up two of the top pitchers in the game during the off season. But Greinke and Miller looked terrible in their debuts. You also have to factor in that the Dbacks are historically bad during the month of April.
Although they play in the toughest division in baseball the Dbacks will be okay. After another week or so the team should be in sink and be able to establish themselves as playoff contenders.
