I believe that looking at a pitcher's record is by no means an accurate way to determine their true effectiveness (because they could just be playing for a team with a great defense), so what I've done here is compared pitchers, below the age of 30, based on their ERA, K's/9IP and BB/9 IP over the last 3 years. The top 3 were:
- Johan Santana (MIN, Age 28) - Santana had a 2.87 ERA (1st) with 9.35 K's/9IP (2nd) & 1.86 BB/9IP (3rd). His top rookie cards, 00 Bowman's Best #'d 2999 & Finest #'d 3000, have been selling for an average TAC of $53.00 & $70.00 this month, respectively.
- Jake Peavy (SD, Age 26) - Peavy had a 3.11 ERA (3rd) with 9.57 K's/9IP (1st) & 2.49 BB/9IP. His 01 Bowman Chrome Ref RC has been averaging around $37.00 TAC this month, down from it's $42.25 average in July, and $48.60 in June.
- Roy Oswalt (HOU, Age 29) Oswalt had a 3.06 ERA (2nd) with 6.74 K's/9IP & 1.98 BB/9IP (4th). His 00 SPx RC #'d 1600 is selling for around $105.00 TAC in August, down from it's July average of $122.80.
Two other pitchers that almost made the cut were C.C. Sabathia (3.58 ERA, 7.81 K's/9IP, 2.10 BB/9IP) and Brandon Webb (3.12 ERA, 7.09 K's/9IP, 2.30 BB/9IP).
