Triples are one of the most exciting plays in baseball. You tend to need multiple things to go right to pull one off. Most players have to hit the ball down into the right-field corner, or the gap in right-center and get a helpful bounce off the wall. Bobby Witt Jr. is not like other players, and he does not need any fortuitous bounces to get to third.
His triple this week against Cleveland is probably a double for anyone else in the Major Leagues, but Bobby is so fast and aggressive in stretching singles into doubles and doubles into triples.
