Greg Maddux got through 7 innings on only 70 pitches last night, and his relievers Kerry Wood and Ryan Dempster got the final 6 outs on 19 pitches, so there were very few opportunities for Craig Biggio to get hit by a pitch.
Carlos Zambrano takes the hill for the Cubs tonight, and he'll bring with him his short history of plunking Biggio. He hit Biggio on May 31 and August 12, 2003.
August 17th has it's own history of Craig Biggio getting hit by pitches. He was hit one year ago today by Randy Wolf of the Phillies, and in 1997 Scott Ruffcorn and Wayne Gomes both hit Biggio on August 17 - also for the Phillies. It will be tough for the Phillies to hit Biggio with a pitch today, but I wouldn't rule it out.
