The Yankees blocked Posada from participating, telling Major League Baseball that Posada was indispensable and was concerned the heavy workload he incurs during the season would be added to and might cause injury, The New York Post reported.
"As a courtesy I called the Yankees to advise them that Jorge wanted to participate in the World Baseball Classic," agent Seth Levinson told the paper. "The Yankees filed an objection that was accepted and Jorge was not eligible despite his desire to play."
Posada felt an urge to represent Puerto Rico in the tournament, wanting to make his family proud.
"I wanted to play since my family is from Puerto Rico, it's where I am from and I was excited," Posada told The Post. "I was the first one to ask for the documents. I can't do anything about it. The Yankees have the last word. I respect that and I will prepare for spring training like I always do."
