Here's a quick preview of a baserunning evaluation that's due to appear in the next Bill James Abstract. No surprise, Bengie Molina is the worst baserunner in baseball. Hes' given up -104 runs on the base paths since 2005. To put that in perspective, he's been 114.9 Runs above replacements with the bat over the same span, so he's given up virtually his entire value as a hitter back via his terrible baserunning. There ares some issues, primarily that virtually every starting catcher is a bad baserunner, and Bengie's probably only given up more like 30-50 runs over the average catcher (I'm guessing here, the list only shows the best and worst 5), but it's another note on the long list of reasons not to want Bengie back.
The surprise: Winn is at +90 since 2005, 5th best in baseball. I knew he was decent, but damn, he's virtually tied with Ichiro. Good thing too, since the Giants needed him to offset Bengie and rank 5th in baseball with +77 team baserunning runs.
