Chan Ho Park (2-3, 4.66) vs. Oliver Perez (2-5, 5.47). Don't be deceived by Park's superficially decent ERA - he's still awful. Chan Ho loves PETCO. He has a 3.43 ERA at home and an evil 6.66 ERA on the road. He also has been pounded by lefties, who've hit .301 with four homers against him. If the Pirates' best left-handed power threat weren't Jeromy Burnitz, they'd have a good chance of knocking a few balls into the right-field seats tonight.
