You’ve no doubt been inundated with articles telling you just how good the 2011 Phillies starting rotation is. The combination of the severe decline in offense across baseball (lowest since 1992) and the four (five?) aces led to some impressive pitching numbers. Prior to yesterday’s games, the Phillies’ rotation had the lowest FIP, xFIP, and SIERA in all of baseball, beating the second-best rotation by 0.41 (Giants), 0.48 (Braves), and 0.49 (Giants), respectively.
In previous years, there has never been a FIP as low as the Phillies’ 2.95, and rarely has a team had such a dominating lead. Dating back to 1990, only the 1996-98 Braves rotations had a larger lead over the second-best FIP.
Even more impressively, since 1990, the Phillies have the lowest FIP and FIP-, which is a FIP index similar to OPS+ (in this case, lower is better; 100 is the league average).
The Phillies’ indefatigable starting rotation has contributed greatly to the team’s greatest run differential through 142 games in franchise history.
“The Phillies are good” articles are rote now, but it’s still fun to look through the numbers and see just how good they really are. Not only are the 2011 Phillies likely to finish as the greatest team in franchise history, but they may just become the greatest team in National League history, at least in the live ball era. The 1975-76 Cincinnati Reds may have something to say about that, but there is at least a debate.
