David Ortiz may have shockwave Achilles’ therapy

Despite having a platelet-rich plasma injection on his strained right Achilles’, Red Sox designated hitter David Ortiz said he likely would undergo more invasive “shockwave’’ therapy during the offseason so that he could be fully healed for the 2013 season.

“I’ve recovered so well,” Ortiz said before Wednesday night’s game against the Rays. “But the doctors said, ‘Hey, for you not to have to worry about that anymore, you should do it.’ And I probably will, just to make sure that I’m not going to have to deal with that anymore. That way, I’ll be absolutely 120 percent by spring training. No question.’’

While he improved after the injection, the results didn’t come as quickly as he had hoped because of scar tissue. “After I got the PRP thing, I was supposed to wait 3-4 weeks and I was kind of getting frustrated two weeks after,’’ Ortiz said. “There wasn’t enough time. When I went from the third to the fourth week, then I started to feel the way I wanted to feel.

“When you get the shockwave, you’re going to be sore for at least 12 days, because it kind of irritates your bones. The skin and the bone are going to be bleeding and inflamed. After that, once you heal, it’s a wrap.’’

Ortiz said he hoped the treatment would help him remove any doubt about the injury that forced him to do two stints on the disabled list.

“I’m like 90 percent, you know, and I haven’t got the shockwave yet,’’ he said. “I’m not limping, I’m not sore, and I’m able to do a lot of things I wasn’t able to do. The doctor checked me out the other day and we did some tests and he was like, ‘Whoa.’ I feel better right now than I how I felt before I got injured.’’

Ortiz, who becomes a free agent at season’s end, was hopeful of re-signing with the club.

“I’m planning on finishing my career here,’’ he said. “Trust me, when I stop playing I’d like to not be packing to go home by this time next year. Right now, I’m feeling pretty good about my injury, finally feeling better and moving forward with that.”

“I definitely feel like there’s something I still have to prove. The thing I keep in mind that I think we can improve is just play better and put ourselves in a better situation for the years to come, and I would like to be a part of it.’’

A bit of a downer

Jon Lester absorbed a 4-2 loss Wednesday night, dropping his home record to 3-10 as the Sox finished with their worst home mark since 1965, when they also went 34-47.

“You definitely don’t want to lose the last home game of the season, but guys battled hard,’’ said catcher Jarrod Saltalamacchia.

Lester threw four no-hit innings before giving up three runs on three hits, including back-to-back homers by Carlos Pena and Ben Francisco that erased a 1-0 lead.

“That fifth inning really took a lot out of me,’’ said Lester, who had felt under the weather the last couple of days, and departed after the sixth. “I didn’t think it was fair to go back out there when I didn’t have anything. I felt fine the whole game, it was just when I got done with the sixth, it all hit me. Legs felt tired and body felt tired from being sick.’’

The Sox took the lead in the second on Daniel Nava’s single, then pulled to within 3-2 in the sixth on James Loney’s sacrifice fly that scored Dustin Pedroia. After Lester departed, the Rays tacked on another run when Jose Lobaton’s ground-rule double scored Jeff Keppinger.

Triple threat

It has been 45 years since Carl Yastrzemski won the last Triple Crown. And he believes Detroit’s Miguel Cabrera has a legitimate shot.

Yastrzemski, who was voted the reserve left fielder (behind Ted Williams) on the All-Fenway Park Team honored before the game, found it hard to believe it’s been this long since somebody won it.

“Somebody’s going to do it, whether it’s Miguel Cabrera this year or someone next year,” Yaz said. “I’m surprised it’s gone on this long, to be perfectly honest.

“When [Pete] Rose broke [Ty] Cobb’s hit record and when [Cal] Ripken broke [Lou] Gehrig’s consecutive game record, I never thought that would happen either, so it’s going to happen.”

Ellsbury out again

Jacoby Ellsbury sat out for the sixth consecutive game with a lat strain, but manager Bobby Valentine was hopeful of getting his center fielder back for this weekend’s three-game set in Baltimore.

“He’s doing OK,’’ Valentine said. “The training room thought another day would be best, and being he doesn’t play [Wednesday] he gets two days rest [with Thursday’s offday].”

Making tracks

Pedroia recorded his 17th and 18th stolen bases of the season, giving him 100 for his career . . . Sox pitchers combined for 14 strikeouts, with the bullpen recording nine . . . Wednesday night’s was the 8,000th major league game played at Fenway, including regular seasons and postseasons of the Sox and Braves.
