Scott Boras
On January 13, 2010, Beltrán had surgery on his knee and was originally expected to miss 8–12 weeks. The procedure was performed by Beltrán's personal physician Dr. Richard Steadman. The Mets stated that the surgery was done without their consent, and the team expressed their disappointment with Beltrán's decision. However, Beltrán's agent, Scott Boras, claimed that the Mets consented to the procedure. Beltrán played his first game of the 2010 season on July 15.
