Michael Conforto has received excellent medical updates from his surgeons and should be swinging a bat by late January, according to his representatives. Conforto, who had left shoulder surgery in September, is working out regularly and should be a full-go for spring training, at which point it will be up to the Mets to decide if they want to limit his at-bats and have him gradually build up and potentially even miss Opening Day. Conforto tore the posterior capsule on a swing Aug. 24, ending what was a breakout season in which he was the Mets’ best hitter. The Mets are looking for first base/outfield types this offseason, in part, to provide some protection in the event Conforto has any kind of setback.
