Keith Hernandez shaves off mustache

After 25 years, Keith Hernandez is undergoing a major change in his life.

The former New York Mets star and current SNY commentator shaved off his legendary mustache for charity on Thursday.

The Schick-sponsored event outside of Citi Field aired live on SNY’s web page and included pre-shave tributes to Hernandez’s "iconic" mustache.

Schick donated $5,000 to Hernandez’s adult day care facility, and fans can enter a contest to win the razor used to shave his mustache.

But the real question is … will Hernandez end up growing his mustache back?

When the Mets hit spring training next year, we should have our answer.
