Freestyle. The freestyle stroke involves the use of muscles in your hands -- the thenars -- and arms -- the biceps and triceps -- to help you glide through the water smoothly. In one motion, your entire body is engaged in the forward action of the freestyle move.
The likelihood of a pitcher completing nine innings if he throws an average of 14 pitches or less per inning is reinforced by the totals of the 89 games in which pitchers did actually complete nine innings of work.
The starting pitcher will generally throw between 90 and 120 pitches before he is removed from a game by his manager (unless he gets battered early on and chased from the game). The expectation is that this will get him through anything from 5 to 8 innings, and the further he goes the better.
