TORONTO -- Aaron Hill isn't going to give up on this season. With each passing day, though, the Blue Jays second baseman understands that he's inching closer to the point where the club may have to declare him done for the year.

Hill just isn't going to be the one to say it.

"No. I'll never say that," said Hill, who has been fighting post-concussion syndrome for the better part of two months. "I'll never throw in the towel."

What Hill will do is continue to chip away at the daily list of light activities he's permitted to take part in. He admits it's been difficult for him to pull back on his personal reins, but Hill is trying his best to abide by the doctor's orders, considering the seriousness of his situation.

One change implemented by Hill is his return to Toronto, where he rejoined the Jays this weekend to at least be around for their series against the Mariners. Team doctors had advised Hill to work through his rehab at the club's site in Florida, but being away seemed to only make matters worse.

"They said, 'Go. Get away from the team,'" Hill said. "They told me I had to be stress free, which is impossible. So, we tried it and I just wanted to come back. They seemed to think that you can just turn it off and relax.

"They say, 'Just relax. Relax.' Come on, don't tell me to relax. I don't know how to relax."

When the Jays were in St. Petersburg for a series against the Rays last weekend, Hill dropped by Tropicana Field and met with Jays general manager J.P. Ricciardi. Hill asked if he could continue his rehab in Toronto, indicating that being separated from the team wasn't helping.

"It just didn't make any sense to be down there anymore," said Hill, who hit .263 with two home runs and 20 RBIs in 55 games this year. "I wasn't doing anything that I couldn't be doing up here. So, I might as well be with the team -- be with the guys -- and be up here."

The 26-year-old Hill has been cleared to ride a stationary bike, work out on an elliptical machine, throw lightly and to hit off a tee. More strenuous activities will have to wait for Hill, who said he's felt significantly better over the past few weeks. It's been two weeks since his last dizzy spell and headaches are few and far between.

Hill still needs to reach a point where he feels no ill effects after upping the intensity of his current workouts before considering running or taking batting practice. The second baseman added that it's tempting to try to push himself harder when team trainers aren't looking.

"I'm definitely learning patience, which is one thing I need to work on," Hill said. "So, it is a life lesson. ... [Head trainer George Poulis] keeps trying to find me, because he knows that I'm going to do something to make him mad -- something I'm not supposed to be doing."

Hill has met with numerous neurologists and talked to a handful of players about his injury. In Florida, former catcher Mike Matheny, who was forced to retire after a concussion sidelined him for the final four months of the 2006 season, told Hill not to "push it, because that's the worst thing you can do."

"I've heard that before," said Hill, who was struck on the side of the head in a collision with shortstop David Eckstein on May 29. "It's just hard to talk myself into this [being] an actual serious thing. That's the only thing I'm having a hard time with.

"Being on the [disabled list], first of all, is embarrassing, personally," he added later. "I'm sure it is for a everybody, because you feel like you're letting your team down, in a sense. I know, you're hurt -- it happens. But the competitive side of you just wants to play."
