Surprise, Ariz. ? Mark Quinn is optimistic he will miss only a few Kansas City Royals’ spring-training games after hurting his hamstring.

Quinn, who tore his left hamstring in June, aggravated the injury while running to first base in the Royals’ 8-7 loss Monday to the Seattle Mariners.

“It’s not feeling too bad,” Quinn said Tuesday. “This is good news. I’ve kind of been through this before. There’s a big knot of scar tissue on the back of my hamstring.”

Quinn and trainer Nick Swartz said the aggravation likely was the result of scar tissue breaking down.

“The thing is, the strength in the hamstring is 100 percent. That wouldn’t be the case if it was a muscle or tendon problem,” Quinn said.

Swartz said it was “very likely” Quinn could return to the lineup by this weekend.

“That’s the goal,” Swartz said.

Quinn was scheduled for an MRI Tuesday, but it might be a few days before the Royals have conclusive reports.

“They just want to make sure it is scar tissue,” Quinn said. “All the symptoms that I have heard from the doctor and trainers say that it is scar tissue.”

Quinn hit .294 with 20 home runs and 78 RBIs as a rookie in 2000, but played only 23 games last season because of injuries. He also had a setback with the hamstring while playing winter ball in Puerto Rico.

“It is frustrating,” Quinn said. “I’ve got to the point where I’ve got to deal with it. It was a pretty traumatic injury to that area.”

Carlos Febles, who was hit in the left hand by a pitch to lead off the game Monday, did not play Tuesday against Oakland, but did take part in on-the-field activities, including batting practice.

“He’s got a little swelling in his right finger, but overall he’s a lot better than it initially looked like,” Swartz said.
