The longest professional game I have heard of is a 33 inning game between Pawtucket and Rochester of the International League (minor leagues) in 1981. The longest MLB game was 26 innings between Brooklyn and Boston in 1920.

MLB starting pitchers pitch every 5 games which means they would pitch no more than two games in one week. The most innings pitched in MLB in 2010 was 250 2/3 by Roy Halladay in 33 starts. This averages out to 7 3/5 innings per gsme and 15 1/5 innings every two games.
So, the pitcher that pitched the most innings in MLB in 2010 averaged between 15 and 15 1/3 innings per week.
Most Major League Baseball teams use a five man pitching rotation. That means that a starting pitcher will usually pitch every five games.
