Vernon Wells doesn't know if Blue Jays fans will use their nickname for him when he returns to Toronto this weekend.

"That was only in spurts," Wells said with a smile. "There were a lot of good times there. Some not so good times."

During the "not so good times" when the home fans at Rogers Centre were not pleased with Wells' performance - or the burden his contract became for the Jays - Wells would joke with reporters that those weren't derisive cheers he was getting from fans. They were just chanting his new nickname - "Boo."

Wells spent 12 seasons with the Blue Jays, winning three Gold Gloves and one Silver Slugger award, making three All-Star teams and moving to or near the top of the franchise's record list in several categories - third in games played, first in at-bats, second in hits, runs, home runs, RBI and extra-base hits.

This weekend will be a first, though, as he returns to Toronto as a visitor.

"I'm looking forward to getting back," Wells said. "Obviously, this is a situation I've never been in before. It's going to be fun and strange at the same time.

"I spent so much time in that city. It's pretty much where I had a chance to grow up. ... It's just a matter of making sure I go to the right clubhouse, the right dugout."

Wells is certainly not returning at his best. He has been a major disappointment this season for the Angels, who sent two players (Mike Napoli and Juan Rivera) to the Blue Jays in a trade for him and agreed to pay all but $5 million of the $86 million remaining on Wells' contract. Through Thursday's loss to the Yankees, Wells is on pace to post career-lows in nearly every offensive category. He is batting a dismal .208 with 16 home runs and 44 RBIs and was recently moved down to sixth in the lineup by Angels manager Mike Scioscia.

But Wells said he won't feel any embarrassment when those numbers are flashed on the Rogers Centre scoreboard in front of his former home fans this weekend.

"No. I honestly don't really pay too much attention to what happened before yesterday," Wells said. "Whatever happened in the past is in the past. Each game we play is so important. That's the fun part of being in this situation (a playoff race). All that matters is what you can do to help the team win that day."
