It depends. In many youth leagues it is based on pitches. When you get into upper youth leagues they then begin to base it on innings. As you get into adult leagues there often is no limit.
10 innings in 3 days
There is no limitation to the number of innings a baseball game can be played. In theory, the game could go on forever as long as the teams are tied at the end of an inning. 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.
Depends on how many pitches are thrown
As of 2014, AAU baseball does not have a mandatory pitch count. ASMI has set one, and all levels of Little League baseball have them.
To be a decent softball pitcher it could take 3-4 years to pitch a softball. Fastpitch that is. The ball is bigger and weighs more than a baseball. The wind up is tricky. Most pitchers that I know have to practice their pitching around 3 to 4 days a week.
If you're talking MLB, then there is no rule. For example the Yankees just pitched CC Sabathia on three days rest, if they wanted to they could start him tomorrow for game 5 of the 2009 world series. But that would probably be extremely unwise.Pitcher's rest is about saving that pitcher's arm, as the more tired or overworked the arm, the more prone the pitcher becomes to injuries. Typically 4-5 days of rest or a pitcher has one start roughly once a week as a general rule of thumb, hence your 4-5 starting rotation.Again no rule exists and say the Phillies win game 5 behind Cliff Lee, and say Lee goes 6 innings and throws 50 pitches. Then if the Phillies need to call on him in game 5, the may just do so for 5 innings. It's rare but has been done before. It would be a suprise to see him at least come out of the bullpen if the above scenario happens.For pitch rest in other leagues, Little League for example: The days vary by the number of pitches thrown by that pitcher. Example: If Johnny pitches on Saturday and throws 60 pitches, then he needs one calendar day of rest, so if he has a game on Tuesday he's eligible to pitch again, but not Sunday. I believe LL (12/13 and under) just added a pitch count rule of a pitcher can throw a max of 80/85 pitches. This is a safety measure to prevent injury and save the kids arm.hope that helps.
There are seven days in a week.
Of course, one week is in a week and a week is comprised of 7 days.
In the MLB, this usually happens more than once per week. Your question will have to be much more specific, because counting all of them ever would be tough.
