Larry Walker, returning to the lineup Wednesday after missing five straight starts with a herniated disc in his neck, homered in his first two at-bats against the Cincinnati Reds. The often-injured outfielder hopes a cortisone shot he received on Monday will allow him to play to his ability. He's struggled while dealing with several ailments this season, hitting .247 with seven home runs and 29 RBI in 58 games. Walker, 38, has talked of retiring after the season. "Hopefully everything gets better quick because I'm tired of really talking about it," Walker said. "I'm back for a day, at least." Walker hit a two-run homer on the first pitch he saw from Ramon Ortiz in the second inning. He hit another two-run shot, his ninth, off Ortiz in the third.
