Commissioner Bud Selig acknowledged yesterday that Barry Bonds is on his mind, but he said he had not decided what course of action to follow. "I spent the airplane ride out here today thinking about it, and I'll continue to do that," Selig said in Anaheim, Calif., before the start of the United States-Mexico game in the World Baseball Classic. "I have made no decision." Because of soon-to-be published books about Bonds and his alleged steroid use, Selig has been urged to investigate Bonds, who can pass the home run totals of Babe Ruth and Hank Aaron this season. Selig was asked if his decsion could be affected by a possible perjury charge if federal authorities in San Francisco accuse Bonds of lying to a grand jury in December 2003. According to The San Francisco Chronicle, Bonds testified that he had not knowingly use steroids. "That's not a big factor for me right now," Selig said.
