Keith Hernandez works grill at Mets game

Good business owners take care of their business.

That's exactly what former New York Mets first baseman and broadcaster Keith Hernandez did Tuesday night.

Hernandez, who played for the Mets from 1983-1989, stopped by "Keith's Grill," the restaurant he started inside Citi Field, to make sure things were running smoothly. He even showed his employees how it's done.

In his time with the Mets, Hernandez was a three-time All-Star, five-time Gold Glove winner, a Silver Slugger recipient, and finished second in MVP voting in 1984.
