A little more than two months after collapsing at Citi Field, Sandy Alderson says he's back to working 100 percent.

Alderson later announced that he was undergoing treatment for cancer.

"I feel good, and things are improving," the general manager said. "It's nice to be back to a routine and working toward the 2016 season, as it would be for anybody."

The Mets announced Dec. 4 that Alderson had undergone surgery for a treatable cancer and was starting chemotherapy.

"I've been working 100 percent since really just after the winter meetings," Alderson said. "I just couldn't travel to Nashville that particular Sunday and Monday. Otherwise I would have been there. But since that time I've been in the office and fully participating."
