Newly enthusiastic about baseball statistics, I followed a link chain that started on Levitt and Dubner's blog and ended up at Hardball Times. When I was talking at the ballgame a few weeks back with my friend Dan about the most underrated baseball statistics, I mentioned "runs scored" and "runs allowed." Hardball Times has a nice graph that succinctly explains the Yankees' improving but still quite modest record: they're giving up a lot of runs.
