CINCINNATI -- Reds outfielder Chris Heisey, who has been on the 15-day disabled list since April 29, is expected to begin a rehab assignment on Monday with Double-A Pensacola.
Heisey, who heads for Pensacola on Sunday, was injured on April 27 trying to beat out a double play vs. the Nationals. He is batting .173 with two home runs and five RBIs in 23 games.
"We hope he goes out to play," Reds manager Dusty Baker said. "Even though he wasn't doing quite as well as he wanted to or we wanted to, we still need him, especially [with] our left-handed strong lineup and especially off the bench."
Reserve outfielder Derrick Robinson has been limited in recent games because of a sore oblique. A switch-hitter, Robinson has been unable to bat from the left side.
"I'm feeling a lot better. Today is the first day I can do everything," Robinson said.
