Oney Guillen, who will begin his second year in the White Sox Minor League system after playing last year for Bristol, pinch-ran for Joe Crede after his one-out double against Scott Eyre in the top of the 10th. Carlos Quentin followed with a single to center, scoring Oney -- wearing jersey No. 77 -- with the tally to break a 5-5 deadlock.
"I was nervous. I was more nervous than he was," said Guillen of his son racing around third base and crossing the plate.
Earlier in the spring, during the White Sox split-squad trip to Hermosillo, Mexico, on March 2, the younger Guillen also joined the team and made a diving play at second base to save a run. But everything that happens during the Cubs-White Sox rivalry always is magnified.
"It was fun," the White Sox manager said of his son getting in the game. "His mom had a chance to see him play."
