Back in April I issued a challenge to all Nationals starters: can you beat Shawn Hill in 2009 VORP?
VORP, or value over replacement player, is a Baseball Prospectus stat the counts the number of runs--or runs prevented, in the case of a pitcher--that a player provides over the course of a season over what the typical AAA fill-in would provide.
Shawn Hill finished the season at 0.2 VORP in 3 starts and 12 innings.
Basically, it's a lock that any pitcher getting regular work should exceed Hill's VORP, because it's a counting stat that adds up based on playing time. Losing the Hill in VORP would be like losing out to Roger Bernadina in RBI. All you have to do is provide anything at all over replacement-level value, and it's a shoo-in.
But Olsen did it. He finished the year at -6.4 VORP.
Incidentally, he's the third Nationals starter to lose the Shawn Hill challenge. Daniel Cabrera ended the year a stunning -14.9 VORP. Ross Detwiler may get another shot, but for now he's at -5.6.
