According to Belisario, the injury occurred approximately a month ago, days after he finished pitching winter ball. It happened when he was swimming with his daughter in the pool at his house in Venezuela.
"No more swminning," he said.
Belisario signed with the Rays following the accident. When asked to explain why he did not notify the Rays of his problem, Belisario said. "No, they sent me a contract back home. I thought [the injury] it was like, nothing. Didn't know it was a fracture."
Normally free agents and traded players must take physicals prior to any deals becoming official. Matt Silverman, Rays executive president of baseball operations, said players signing Minor League contracts aren't generally asked to have physicals prior to signing.
If Belisario makes the team, he will earn a $1.5 million salary.
Belisario, 32, looked like a good candidate to earn a spot in the bullpen this spring. He speculated that he would be pitching in games by April 15. He went 4-8 with a 5.56 ERA for the White Sox in 2014.
