Ortiz, who has a sore right Achilles’ tendon that he says is not torn, said he hopes a platelet-rich plasma injection will allow him to return in September.

“You guys already know I'd like to be out there playing, helping out,” he said (via “The good thing that we talked about today [with doctors] is we're going to try this one PRP injection to see how it goes in next couple of weeks. And if I'm good, I can just go back out there and play.”

In PRP, a patient’s blood sample is spun at high speeds to produce plasma, which contains a high concentration of platelets, and the PRP is injected into the aching muscle.

“You guys know I live for this,” Ortiz said. “And there's not one thing that I would like to do more than be out there performing for our fans. I had [PRP] done before and I believe in that big time. The thing that we didn't get it done before because we thought that wasn't a need in my case but at this stage, at this point, I gotta get through it. The doctor brought that up and I want to give it a try.”

Ortiz, 36, had been having one of his best seasons, with a .318 average, 23 home runs and 60 RBI until he was placed on the disabled list July 17. After a 35-game absence, he returned Friday night against the Kansas City Royals and went 2-for-4 with a double and two RBI. He has not played since.

Ortiz, who can become a free agent after the season, is the last member of the team that won the 2004 World Series still on the roster. Last week, the Red Sox unloaded their problem children and their mega-contracts to the Los Angeles Dodgers in a blockbuster deal that officially kicks off the Ben Cherington era.
