Roy Halladay says that he isn't interested in a contract extension, as he looks to test the free agent market next winter. Blue Jays general manager J.P. Ricciardi explained on Thursday why the team's stance on trading Halladay changed. Entering the season, Toronto claimed that they wouldn't trade the pitcher, but rather try to extend his contract. "What's changed is Roy has told us that he's going to test the free-agent market," Ricciardi said during a radio interview on The FAN590.
