New York Mets
Jenrry Mejia has a fourth option the Mets can use in 2013. So the right-hander does not necessarily have to make the major league ballclub out of spring training.
Assuming the Mets sign a veteran starting pitcher to round out the rotation, Mejia logically would compete for a bullpen spot. But, like with Jeurys Familia, Mejia can be sent to Triple-A Las Vegas to work in the rotation without being exposed to waivers if he does not make the major league club.
Most players have three options years, but Mejia is allowed a fourth because his first three were used at such a young age.
