Betances (Achilles) agreed to a one-year, $10.5 million contract with the Mets on Tuesday, Andy Martino of SNY.tv reports.
The right-hander suffered an Achilles injury in the middle of September after dealing with a lat injury earlier in the season, but he is expected to fill a key setup role for the Mets and could slide into the closer role if Edwin Diaz's struggles persist. Betances is expected to be ready for spring training.
