Career (may be incomplete) $9,848,000
I'd say they got the job done. If you look at his career stats, it wouldn't be surprising if he started using them in 1998. For most of his major league career from 1989-1996 he was a bum, and had an ERA over 6.00 each of his last two years with Cleveland. Then in pitched in the minors in 1997, getting released by one team and putting up an ERA around 6.00 for the year. Then in 1998, he pitched for AAA Buffalo and had an ERA under 4.00. From 1999-2005 he was in the big leagues, and his ERA+ was average to above-average for 6 of those 7 years (only 2005 was a very bad year). So I guess if he started using in the late '90s, then they really did work.
