What First Five Innings (F5) means
The first five innings market settles based purely on the score after five complete innings, regardless of what happens in the rest of the game. It's a baseball-specific market designed to let bettors isolate the starting pitching matchup - the single most influential handicapping factor in baseball - from the unpredictable variance a shaky bullpen can introduce in the later innings, which is exactly why sharp baseball bettors often prefer F5 markets over full-game lines when they have a strong opinion on the starting pitchers specifically.
