So as to not sidetrack the Ron Cey/Steve Garvey discussion

This is the part I'll focus on.

I don't know if you're aware of a stat called WPA (Win Probability Added). If not, here's a link.

Basically, WPA looks at a team's likelihood of winning a game after each plate appearance. If the likelihood increases the player is credited, if the likelihood decreases the player is debited.

For example, a leadoff single increases a team's Win Expectancy by about 3.5%. The player leading off would get WPA of .035.

Likewise, if he made an out the visiting team would be about 3.5% less likely to win, and he would have .035 subtracted from his WPA.

A home team trailing by 1 run in the bottom of the 9th with a man on first and 2 outs has about a 10% chance of winning. A walkoff home run increases the chance to 100% so a batter would be credited with .90 of WPA.

In 2007 Jimmy Rollins had a cumulative WPA of 2.69. What does that mean? To put it in context.

He was 25th in the majors and 3rd on his team behind Utley (3.40) and Howard (3.08).

His hits were not all that timely.
