It rarely happened. A few times there was an umpire for my tournament pickleball game. One umpire had a delightful sense of humor, which improved my game experience. It was an intangible benefit that likely improved that quality of play by both teams. Does that occur in baseball?
On 3 June, Marte was caught off first base, but the umpire called safe. The other team challenged the call. New York called him out. The game thread had some grumbling. I felt the grumbling was justified, so I went back and replayed two views of the play on my streaming service and stopped one view at the exact moment when Marte was tagged.
