Ramirez had a 0.96 ERA in 33 games before he was placed on the DL. He went to Mesa, Ariz., to rehab and pitched in two games, totaling 1 1/3 innings.
"I just feel like the ball is coming out good again," Ramirez said Sunday. "I feel loose and ready to go."
He credited athletic trainer P.J. Mainville and strength coach Tim Buss with putting him on a program that has helped him build up arm strength.
"I just have to keep up with that and finish out the year strong," Ramirez said.
He did nothing except play catch for the first four or five days on the DL.
"The team is looking out for me," Ramirez said. "I want to finish the year strong."
