Manager Tom Trebelhorn #41 of the Chicago Cubs argues with an umpire during an Major League Baseball game against the New York Mets circa 1994 at Shea Stadium in the Queens borough of New York City.
Well, that made this one pretty easy. Yes, that’s obviously Trebelhorn — and he managed the Cubs for only one season, the strike-reduced 1994 season, so it has to be that year.
It’s Shea Stadium — but it’s also some sort of special event day, because there’s bunting on the wall. That would make it either Opening Day or a holiday.
