"We're trying something a little bit different, doing the laser therapy on it," said Lowrie. "It feels like it's getting a little better. I haven't been swinging as much, so that might be why. So far, I feel like I've made progress."
What does the laser therapy do in particular?
"From what I've been told, it promotes deep healing," said Lowrie. "I just think it's a different approach than the ultrasound."
While Alex Gonzalez is entrenched as Boston's starting shortstop, depth has been compromised at that position now that Nick Green is on the shelf indefinitely with what could be disc issues in his back.
Perhaps that could create an opening for Lowrie to earn a spot on the postseason roster if he can get healthy enough by then.
"I think I'll have to cross that bridge when we get there," said Lowrie. "It really kind of depends on how my wrist progresses the rest of the year. I think it's a decision that will have to be a joint one. Obviously, they'll have the final say, but I'll have to be as honest as I can on how my wrist feels."
Since being added back to the roster on Sept. 8, Lowrie has appeared in four games, but he has had just one at-bat, a key pinch-hit single that fueled a dramatic comeback victory over the Angels on Wednesday.
There is still time for Lowrie to salvage something from a lost season.
"If all things go the right way, hopefully, I'll feel that I can do something from the left side, too, [by the postseason]," said Lowrie. "It's not that I couldn't go out there and play. I know I can do that. I went out there and showed that I could play. But it's just that playing and being productive are two different things."
Lowrie got a taste of October last season, serving as Boston's starting shortstop throughout a run that ended in Game 7 of the American League Championship Series.
"I think either way, I would imagine I'll be here [in the postseason]," said Lowrie, who punched Boston's ticket to the 2008 ALCS with a walk-off single vs. the Angels in the AL Division Series. "If I'm not on the roster, I would be that alternate. But at the same time, obviously, I want to be a part of that. I know what it's like now, even after just one year. You hear guys who have played 10 or 12 years talk about it. But even me, with last year being the first time I experienced it, you know that's why we play."
Lowrie knows that he can't force anything just because Green is hurt. The Red Sox brought veteran utility man Chris Woodward back to the mix on Monday, giving the team another option for in-game substitutions.
Has Lowrie gained anything from this frustrating season?
"It hasn't been easy, but I feel like it was an opportunity for me to realize how much I want to be here and want to be playing," said Lowrie. "I feel like I never lost that perspective."
