Beltran had six at-bats -- three from each side of the plate -- and had two singles. A team official said it was a step in his rehabilitation and that Beltran did "nothing crazy" as far as baserunning.
Beltran, 33, underwent Jan. 13 arthroscopic surgery on his arthritic right knee, and subsequently returned to the Vail, Colo., doctor who performed the procedure to be fitted for a brace because a bone bruise continued to trouble him.
Beltran is in the sixth season of a seven-year, $119 million contract.
After playing June 21, 2009 against the Tampa Bay Rays, Beltran was shut down last season until September to rest the bone bruise in the right knee.
