"I'm not 100 percent, but I'm pretty close," Estrada said. "Pitching-wise, my leg doesn't affect me at all. Just mentally and maybe a release point I have to work on or the windup, I still feel a little out of whack. It's not too bad."
A right quadriceps strain has kept Estrada out of action since May 23. He stressed that he shouldn't have any problem making his start or feeling comfortable pitching or fielding by game time on Tuesday.
"If people want to try to bunt on me, go ahead, because I'm able to get to everything," he said.
Estrada was nearly perfect in two rehab starts at Triple-A Nashville, throwing three scoreless innings June 16 and allowing one run in five innings on June 21.
"I talked to him and he said the first night he really didn't feel that bad, he was just missing off the plate a little bit," said manager Ron Roenicke. "The last start he said he felt really good."
