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.
Let's also say  the average inning lasts 30 pitches (15 per half inning). We'll  approximate the total number of pitches per game at 270. That would  make 30 baseballs used per game (270 / 9). If all 30 teams played  the entire 162 scheduled games in a season, that would be 2,430  games played.
