If you go with the best first half of the season approach, Zambrano is not an All-Star this year. His "first season" can't be ignored...Zambrano is currently 33rd in the NL in VORP at 14.8. The trio of Rich Hill (13th in NL, 24.9), Ted Lilly (28th , 15.9), and Sean Marshall (32nd, 15.0) are better by this metric on his own team. Via SNLVAR, another marker of a pitcher's value, Z is 23rd in the NL and trails Rich Hill (15th NL) of his own team. If any Cub pitcher is an All-Star this year it is Rich Hill.
