The Colorado Rockies are off to a 7-33 start, one of the worst in major league history. That led to the firing Sunday of manager Bud Black. Now, it’s Warren Schaeffer’s turn to navigate the Rockies away from a season that’s careening toward infamy. The Rockies have the worst start since the 1988 Baltimore Orioles began 6-34. Colorado is on pace for 134 losses a season after the Chicago White Sox went 41-121, the worst since baseball adopted a 162-game schedule in 1961. Promoted from third-base coach to interim manager, Schaeffer inherits a team that’s second-to-last in runs despite playing home games at hitter friendly Coors Field. The pitching staff has surrendered the most runs in the big leagues and fanned the least amount of batters.
