HAVANA -- Ace pitcher Yadel Marti and star outfielder Yasser Gomez have been thrown off Cuba's top league team for "a grave act of indiscipline," likely ending their hopes of playing in the 2009 World Baseball Classic.

The one-sentence announcement Friday in the Communist Party newspaper Granma offered no details on why Marti, picked to the all-tournament team at the 2006 WBC, and Gomez, a former Olympian, were released from Havana's Industriales.

Two people close to the team said the action came after the pair was caught trying to defect to the United States. The two people spoke on condition of anonymity and did not elaborate, fearing it could lead to problems with the Industriales.
