CHICAGO -- Barry Bonds plans to play in next month's All-Star Game but could change his mind if his father's health worsens.

Bobby Bonds has lung cancer and is undergoing chemotherapy. He also had an operation last year to remove a cancerous tumor from his kidney.

"If my father's condition got worse, what would I do? I'd stay home. I wouldn't go," Barry Bonds said. "That's just common sense."

Bonds spoke before Thursday's game against the White Sox, the host of the All-Star game on July 15. Right now, he plans on attending.

"It's only based on my father's condition," the Giants slugger said.

Bobby Bonds, 56, played for the San Francisco Giants from 1968 to 1974 and for seven other teams during a 14-season major league career, hitting 332 homers and stealing 461 bases. A three-time All-Star, he had 30 homers and 30 steals in a season five times.

He is a former Giants coach and currently is a special assistant for the team.

"I've never played baseball without my dad. My dad's always been there. Now I play alone," Barry Bonds said. "I could take a bad swing on the field, and my dad could make a phone call in five seconds and tell me what's wrong. There's no more phone calls."

According to a report, pitcher Jason Schmidt last weekend suggested that Bonds wants to play every day because the games allow him an escape from his father's illness.

Bonds agreed, to an extent.

"You think about it, believe me," he said Tuesday. "There's no time you don't think about it. You try to come out here and not think about it, but it crosses your mind. It's about three or four hours just where your mind is doing something else besides thinking. In baseball you think, but you don't have to think hard.

"The stress level is not as high."
