T.J. Rivera's RBI single turned into a three-run race around the bases after a wild throw

When T.J. Rivera lined a single back up the middle in the bottom of the sixth inning of the Mets' 7-5 win over the A's on Friday night, it wasn't an ideal result, but the A's would have taken it. 
That ... didn't happen this time. As Asdrúbal Cabrera came around to score, Rajai Davis' throw went to third base to try to cut down Yoenis Céspedes. That didn't work out, but third baseman Matt Chapman saw a chance to get Rivera at second. Unfortunately, his throw went wide and the ball took a trip over the great right-field plains. Rivera was able to race around the bases for a three-run Little League dinger. 

Of course, there are some that think this doesn't live up to the definition of a Little League home run. Chuck Hildebrandt gave a presentation at SABR's annual conference in 2015 that suggested that a Little League homer requires a minimum of two errors on the play. That means a true Little League shot is more akin to this: 

But if Rivera's race around the bases isn't a Little League home run, then ... what do we call it?
