MLB Network counts down its version of the 20 greatest games played since about 1950. The network first came up with 50 games and a "blue ribbon panel" -- aided by fan votes -- whittled that to 20. Hosts Bob Costas and Tom Verducci dissect each game, and given the format, with each episode running at least one hour, there's plenty of time to delve into nuances such as pitch selection, defensive alignment, managerial moves and so on. Also making each episode must-see TV for longtime baseball fans is the ex-players and managers who join Costas and Verducci to provide insight. Bucky Dent, for example, talks about his famous home run in the 1978 American League tiebreak game, and Johnny Bench and Fred Lynn reminisce about Game 6 of the 1975 World Series, the No. 1 game on the list..
