From baseball prospectus:
Top 5 NL Rookie Pitchers, by Value Over Replacement Player (VORP)
Player, Team, IP, VORP
Zach Duke, PIT, 46.7, 20.7
Rob Tejeda, PHI, 61.0, 17.7
Gary Majewski, WAS, 51.3, 12.2
Brad Halsey, ARI, 131.3, 11.4
Matt Belisle, CIN, 66.7, 11.0
hopefully belisle, wagner, coffee, shankelford, and standrige can improve on this year and be a solid pen for a few years to come. All are relatively young and have shown serious signs of life.
