New Los Angeles Angels second baseman Danny Espinosa hit .209 last season, yet I would tell Angels fans that they got themselves a good baseball player.
It wasn't that long ago that you couldn't make that argument. A player with a bad batting average was a bad baseball player. There was the occasional exception to the rule, but more often than not, a .210 or .220 meant that you stunk.
But that's not true anymore. You can still be a highly useful player with a low batting average. It's one of the things that makes a stat like WAR great -- it helps identify a good player where you have to dig to find their value.
