After pitching in Venezuela over the winter, Escobar arrived in Port St. Lucie with "weakness" in his shoulder and was relegated to playing catch.
Escobar then spent most of the 2008-2009 seasons sidelined by shoulder problems. General manager Omar Minaya signed Escobar to a contract worth $1.25 million last winter with the idea the right-hander could claim the eight-inning setup role.
But that plan was in trouble almost from the first day of camp.
Now Escobar will have surgery tomorrow to repair a torn capsule in the front of his right shoulder. It's an injury similar to the one that cost Dolphins quarterback Chad Pennington most of the 2009 season.
Escobar's season could be in real jeopardy.
