"He says he feels fine," Padres interim manager Pat Murphy said Wednesday. "He says the knee is ready. He stole a base. He's running."
Spangenberg has been on the Padres' disabled list since June 28, the day after he bruised a bone in his left knee during a collision at second while turning a double play.
At the time of his injury, the 24-year-old left-handed hitter was coming into his own. He was hitting .254 with eight doubles, two triples and two homers with 11 RBIs in 177 at-bats.
