Pirates lefty Francisco Liriano -- who faces the Giants on Wednesday -- is just a couple of outs shy of giving manager Clint Hurdle a quality start in five of his six outings; he is 4-2 with a 1.75 ERA. Opposing Liriano will be San Francisco lefty Barry Zito, who is 2-3 with a 3.73 ERA in seven career games against Pittsburgh.
