In 2004, Contreras gave up less hits (166) than IP (170.1) but he still issued a ton of walks (84) for a 1.47 WHIP on the season. If he keeps his walks down like he did last season (75 BB in 204.2 IP), I will believe that he's the real deal. But he's still very old so he may not keep up this level of performance anyways.
