Manzella gave the finger a good test when he participated in a simulated game Wednesday and faced teammate Brian Moehler.
"On the swings I took off Moe I felt pretty good," he said. "I had one where I kind of foul-tipped it and didn't square it up and that was good and I responded well to that. I'm definitely ready to get going and get into a game."
The plan is for Manzella to get two at-bats in two games and then increase to three at-bats in two games. When he's prepared to play a full game, he will continue his rehab at Triple-A Round Rock. The longest the rehab could last is 20 days, but Manzella hopes it won't be that long.
"It's going to depend on how I feel," he said. "I think it's going to be on my end, basically getting into playing shape and letting them know when I'm physically ready to play."
