Major League baseball star pitcher Roger Clemens has threatened to boycott his eventual induction into the Hall of Fame if he is not allowed to go in as a New York Yankee.

Clemens, who recently reached a major milestone with his 300th career victory, said that after 20 years in the game, he wants to decide whose hat he'll wear when he goes in the baseball shrine. And he wants a New York Yankees cap on his plaque.

Clemens could also go into the Hall as a Toronto Blue Jay or a Boston Red Sox. He pitched 13 seasons for the Red Sox before joining Toronto for two seasons as a free agent and winning the Cy Young Award before asking to be traded.

But he became estranged from the Boston organization after general manager Dan Duquette described Clemens as being in the "twilight" of his career when he was allowed to leave the Red Sox as a free agent after the 1996 season.

Clemens is likely to make it into the Hall of Fame in 2009 if he retires as planned this year, but said unless he is allowed to be inducted as a Yankee, there could be a vacant seat at the ceremony.
