In 2000, Antonio Alfonseca was 45/49 in save opportunites. His peripherals indicated that he wasn't as good as his save numbers indicated. Those peripherals proved to be predictive. In 2001, he was 28/44 and in 2002 he as 19/28. While I hope Dempster is as good as his 33/35 might lead some to believe, there is enough reason to be concerned.
