How have the Pirates, who lost 105 games last season, vaulted to the top of the standings in late July? The great Joe Sheehan offers an explanation:
The Old New Inefficiency
↵Pirates Defensive Efficiency 2010: 0.689
↵Pirates Defensive Efficiency 2011: 0.718
↵That’s a jump from last in the league to third (and in a virtual tie for 2nd place with the Giants), which goes a long way towards explaining their 28-point bounce (to the good) in batting average allowed.
