The right-hander, who threw the 21st perfect game in Major League Baseball history on Saturday against Seattle, returned to Chicago on Tuesday afternoon to join his wife, Kristan, for the birth of their first child. Humber still is scheduled to start Thursday night's series opener against Boston at U.S. Cellular Field, when tickets will be discounted in honor of and in conjunction with Humber's perfecto.
"He's fine. He was [going to be] flying home [on Wednesday] anyway," said White Sox manager Robin Ventura of Humber. "He's no good to us today, so he can go home."
