23. Pedro Astacio (Rockies Career WAR 10.8)
If you haven’t noticed yet, this installment is extremely pitcher heavy.
Pedro was the first truly successful pitcher in Denver and gave hope that they could roster a competent rotation. He’s also a prime reason the humidor was installed at Coors Field. He started off strong winning no less than 12 games from ’98-’00.
This stretched culminated in his best year of 1999 where he won 17 games, struck-out 212, with a 5.04 ERA(Gave up 38 homers, hence the beginning of the idea of the humidor, imagine how many more wins and lower that ERA would have been). This accumulated a 115 ERA+ and 5.9 Pitcher WAR.
When he retired in 2006, he was the all-time Rockies win leader and still sits 6th on that list with 53.
