The Nationals signed Chien-Ming Wang to provide leadership for the staff:
“The type of pitcher we’re looking for,” Rizzo said, “is a good leader-type of guy that throws a lot of innings, that has shown he can win in the big leagues and really lead our staff — not by having the best stuff on the staff but by showing how to be a professional and how to be a winner and how to pitch 200 innings in a season.”
It should be noted in his two full seasons in the majors, Wang only exceeded 200 innings once. (He did pitch 199 1/3 innings in 2007, and so we should probably give him two 200 IP seasons.) It’s been a long time since that 200 IP season, so I would bet against Wang reaching that plateau in 2012.
Wang is a good pitcher when his sinker is working. That’s the best reason to sign him to a contract, and that should be more than enough.
