CINCINNATI, Ohio - Cincinnati Reds first baseman Joey Votto is scheduled to make a rehab appearance Tuesday at Single-A Dayton, perhaps the last step of his comeback from two surgical procedures on his left knee.

Votto hasn't played since July 15 after being injured sliding into third base on June 28 in San Francisco. The 2010 National League Most Valuable Player started the All-Star Game and was hitting .342 with 14 home runs and 49 runs batted in when he left the lineup.

"I'm a little apprehensive because I haven't played in a long time," Votto said before Sunday's game against St. Louis. "The work on the field has been good. I have a long way to go on my swing. The things that I'm uncomfortable about will come out when I play in Dayton."

Going into Sunday's series finale, the Reds were 27-13 since Votto left the lineup.
