1964 Phillies. A team with several great players just collapsed.
The team is notable for being in first place in the National League since the opening day, and then suffering a drastic collapse during the final two weeks of the season. The "Phold of '64", as it became known, is one of the most infamous collapses in baseball history.
To be fair gmason beat some very good teams to get to the final four. If I recall MSU, UNC and, I don't remember the third but I think it was another good team. It was a devasting loss but gmason deserves tons of respect, that was a very good team, under rated. They were 27-8 and the few P5 teams they played in the regular season were all close games.
