While Colorado’s run differential of -89 (106 runs scored and 195 surrendered) is the worst in the MLB, the Rockies’ Pythagorean winning percentage — a formula that roughly estimates how many wins a team should have, based on its runs scored and surrendered — puts them a hair short of eight wins out of these 34 games.

With every game, the Colorado Rockies’ season seems to be getting worse. And a day after a historically bad loss, the team has parted ways with manager Bud Black.

It’s a gloomy situation that has the Colorado Rockies off to a 7-33 start — one of the worst in major league history — and led to the firing Sunday of manager Bud Black.
