Jason Schmidt wasn’t as good as you remember. He was mediocre at best for the Pirates after they acquired him from Atlanta in the Denny Neagle trade. It wasn’t until he landed in San Francisco did he emerge as one of the league’s best starters, twice finishing in the top 5 for NL Cy Young.
The beginning of his career was as bad as the finish, when he flopped as a free agent with the Dodgers. With the Braves he showed little ability to keep runners off base, walking 5.4 and allowing 10.3 hits per 9 IP. He pitched 22 games for the local nine, starting 13, and left Atlanta with an unsightly 6.45 ERA and 1.745 WHIP.
Granted, he was just 23 but the 20 worst does not distinguish between rookies and veterans.
