Chad Qualls, Kevin Millwood, and Sample Size
The San Diego Padres have reportedly signed Chad Qualls to a one-year contract for about two million dollars in an effort to restore some of the bullpen depth they’ve traded away this winter. In signing Qualls, they are making a pretty big bet against the predictive power of ERA, considering he posted an atrocious 7.32 mark last year.
However, the Padres understand how to build a bullpen on the cheap, and they also realize that ERA is a pretty lousy way to evaluate relief pitchers. To illustrate the point, let’s compare Qualls’ season to that of another free agent, Kevin Millwood.
Qualls had the following miserable line last year: 59 innings, 85 hits, 56 runs, seven home runs, 21 walks, 49 strikeouts. That’s just not good, no matter how you slice it.
Millwood had the following miserable line last year: 51 innings, 86 hits, 54 runs, 11 home runs, 25 walks, 36 strikeouts. That’s even worse than Qualls’ performance.
