Matt Kemp -- Jameis Winston Could KILL it in the MLB

Jameis Winston just got a HUGE endorsement for his dreams of playing in the MLB ... 'cause Matt Kemp tells TMZ Sports, Winston has the athletic skills to be the next great two-sport athlete.

The injured Dodgers star was hobbling around Beverly Hills this week ... when we asked him if he thinks the Heisman winner has what it takes to be the next Bo Jackson or Deion Sanders.

Kemp admitted he hasn't actually seen the kid play baseball yet ... but with his freakish athletic ability and cannon of an arm ... he thinks the FSU QB could be a stud in the majors.

FYI -- Winston was the 15th round pick for the Texas Rangers coming out of high school ... and will be playing right field, DH, and pitcher for the #5 ranked Seminoles in the next few weeks.
