Ankiel, who will get most of the playing time in center field, was able to work out with his teammates before Friday's game against Cincinnati without any problems. Ankiel was put on the disabled list in Spring Training because of a strained left quad.
"You are going to see Rick Ankiel tomorrow," manager Davey Johnson said. "He is in great shape. He had a great rehab program. He did awfully well. ... He looks good to go."
The return of Ankiel means that Roger Bernadina will be a reserve. He will come off the bench as a pinch-hitter, pinch-runner and defensive replacement. Bernadina had received most of the playing time in center field, and after going 1-for-4 with a walk Friday, is hitting .143 with an RBI this season.
"As far as baseball experience goes, he is kind of a babe in the woods, but he has a lot of potential," Johnson said about Bernadina. "We haven't seen the best of him yet. I certainly haven't given up on him."
