Oliver Perez is perfect through four with five strikeouts.

Update: With 2 out in the fifth, Nomar walked to break up the perfecto, then Grudzielanek singled to break up the no-no. It's 0-0 with the Cubs threatening.

Update: Helping his own cause, Carlos Zambrano draws the third walk of the inning to drive in Garciaparra. Cubs lead 1-0 as they try to stay with the Giants for the wild card.

Update: Carlos Zambrano puts in his bid for the Cy Young award with 7 1/3 shutout innings to lower his ERA to a league leading 2.64, pending Randy Johnson's performance (Johnson has given up two runs so far, but both are unearned). Carlos also gets his 15th win as the Cubs prevail 1-0.
