OK, lets say 4 guys without much of or very strong major league track records are pitching for 3 spots on the Yankees roster, and these are their lines in Spring Training:
Pitcher #1: 9.2 IP/1.86 ERA/13 H/1 BB/10 K
Pitcher #2: 9.0 IP/2.00 ERA/9 H/3 BB/12 K
Pitcher #3: 7.2 IP/0.00 ERA/1 H/0 BB/7 K
Pitcher #4: 9.1 IP/3.86 ERA/11 H/3 BB/ 10 K
Pitcher #3 happens to be Scott Patterson, who was nearly perfect this Spring and all of last season at AA, while Pitchers #1,2 and 4 were Ross Ohlendorf, Brian Bruney and Jonathan Albaladejo. Clearly, Patterson outpitched the others, but was the only one who was left off the roster. Granted, Ohlendorf and Albaladejo are likely to be optioned down in early April when Andy Pettitte comes off the DL and a long reliever is promoted, but it is still pretty absurd that Patterson did not even get a chance at the big league level over Brian Bruney, who has proven at the MLB level that he cannot find the plate.
