What in the world has happened to the Colorado Rockies ? At the end of April, everything seemed to be sunny and rosy in Denver. Once May arrived, however, the storm clouds descended — literally — onto Coors Field, bringing doom and gloom to a franchise that’s already experienced enough pain throughout its 33 years of existence. The Rockies haven’t won a game in May and are currently on a six-game losing streak, the latest defeat being a 10-5 loss to the also-lowly New York Mets. Absolutely nothing has gone right over those six games. The pitching — apart from a Tomoyuki Sugano masterpiece — has been mediocre at best and downright horrendous at worst. The offense, which should be this team’s strength, has disappeared at all the wrong moments.
