A couple of us in the press box were discussing the Value Over Replacement Player of the Nationals' outfield -- in other words, the number of runs a player contributes over a replacement player that could be had for almost nothing, given the same number of plate appearances. A VORP of 1, for example, means the player contributes one run per season more to a team's total than a theoretical replacement.

Of the 666 position players in baseball currently listed by Baseball Prospectus, here are a few numbers of interest:

No. 479 (tied): Willie Harris, -0.8
No. 535: Lastings Milledge, -1.4
No. 572 (tied): Rob Mackowiak, -2.1
No. 642: Elijah Dukes, -5.1
No. 655, Wily Mo Pena, -6.7
No. 664 (tied), Austin Kearns, -9.6

And if you were wondering, the Nats player with the highest VORP is Cristian Guzman, who comes in at 13.4, good for 36th place among all major-leaguers.

(Full disclosure: I'm kind of a geek, too).
