Travis Kelce Throws Comically Bad First Pitch At Guardians Game

Travis Kelce might be a future Hall of Famer on the gridiron, but he's apparently not much of one on the baseball diamond ... 'cause he just threw out the first pitch at the Guardians game -- and it was terrible.

The Kansas City Chiefs star was tapped by his home state squad to perform the ceremonial throw at Cleveland's home-opener against the Mariners ... and there were some big expectations for the toss.

After all, Kelce's one of the best NFL players on the planet ... and he was a H.S. baseball star who some thought could have had an MLB future if he stuck with the sport.

But, Kelce was anything but great on the bump Friday ... hurling the baseball straight into the ground.

The throw was so bad, Shane Bieber -- who was playing catcher -- couldn't even snag it ... and it rolled all the way to the backstop!!

Kelce was pretty embarrassed -- he raced after the pitch immediately after throwing it ... but ultimately stopped to have a laugh with Bieber over it all.

It didn't take long for Kelce's quarterback to get wind of the comically bad throw -- with Patrick Mahomes clowning him over it on Twitter.
