HISTORICAL SERIES VICTORY PROBABILITIES (UP 2-GAMES-1)

Here's what has happened -- in both the series and the following game -- when an MLB/NBA/NHL team led a best-of-7 series 2 games to 1. "Site" means the site (H=home or V=road) where a team played Game 1: For example, the row in which sport=MLB, round=Finals, and site=V refers to MLB teams with a 2-games-1 MLB World Series lead, having played Game 1 on the road; for a second example, the row in which sport=NHL, round=Semis, and site=H refers to NHL teams with a 2-games-1 NHL Stanley Cup Semifinals-round lead, having played Game 1 at home. Theoretical series victory probability for series-leading team = .6875 (based on theoretical game victory probabilities of .5). Table updated through Fall 2017.
