>Slugging percentage is a misleading stat, IMHO -- I'd much rather look at RISP averages and on-base percentage. That's what tells me how dangerous a hitter *really* becomes. Lots of decent players with timing, some bat speed and a few guys around them in the lineup can have a good SP (Bonds, Manny Ramirez and A-Rod are excellent current examples, and I'd NEVER include them on a list of "pure hitters") -- but if I was managing a club, I'd much rather see a guy with a high RISP average who always seems to be able to get on base coming up in a clutch situation than somebody who could hit the ball out on any swing but who can't sacrifice worth a damn and strikes out 50 times a year with a runner on third and less than two out.
Have you read "The Numbers Game"? I'm pretty sure that's the one that convinced me about OPS.
