Toronto righthander A.J. Burnett claims that he hasn't yet decided on whether or not he'll opt out of his contract at the end of the year, according to The Philadelphia Daily News. However, Blue Jays manager Cito Gaston doesn't appear optimistic about having Burnett return. "It certainly looks like A.J. won't be here," Gaston said. Burnett is 16-9 with a 4.51 ERA in 171 2/3 innings this season.
