Watch: Cueto goes full tilt during intense beach workout

Johnny Cueto may be spending his offseason under the bright and beautiful sun in the Dominican Republic, but that doesn't mean he's spending all of his time relaxing.

The San Francisco Giants right-hander posted a series of workout videos from the beach to his Instagram on Saturday, showing what it takes to become one of the top pitchers in baseball.

Cueto finished an impressive 18-5 with a 2.79 ERA and 1.09 WHIP during the first year of a six-year contract he signed with the Giants prior to the 2016 season.
