I’m a huge Red Sox fan. (That noise you just heard were all the Yankees fans skipping ahead to the comment section. Don’t wait, guys. I’ll be right there.) This season began with the highest expectations, after the Sox won the offseason by acquiring superstars Adrian Gonzalez and Carl Crawford and by rebuilding their bullpen. Experts and fans alike were predicting a 100-win season (their first since 1946) and a nonstop flight to the World Series. Instead, the team got off to a horrific start, going 0–6 and 2–10. Since then, they’ve begun to turn it around, finally reaching .500 on May 15. Now they’re just half a game out of first place in the tight AL East.
Part of the reason for this turnaround has been excellent pitching. Jon Lester, the young lefthanded cancer survivor, sits atop the American League leaderboard with a 6–1 record; no AL pitcher has more wins. Josh Beckett, the veteran star rebounding off a couple down years, is 3–1.
Now just looking at wins, you’d think that Lester is outperforming Beckett. But you’d be wrong, because win totals tell you very little about how a pitcher is performing. Just as looking at hours-billed totals tell you very little about how a small-firm lawyer is performing.
Better ways to measure performance (for pitchers and lawyers), after the jump.…
