According to Jesse Sanchez, Cuban right-hander Yasiel Sierra has been declared a free agent by MLB and is now able to negotiate and sign with any team. That means he’s already gone through the process of getting unblocked by the Office of Foreign Assets Control as well.
Sierra, 24, impressed during a showcase event earlier this offseason and has reportedly been visiting interested teams these last few weeks. It’s unclear if the Yankees have any interest but, to be fair, no teams have been connected to Sierra yet. His market is a big mystery right now.
