Yes, before 1883, a pitcher could not deliver a pitch above his waist.
On average, there are about 11 to 13 pitchers on every Major League team. There are, on average, 5 starting pitchers, a closer (last-resort pitcher), a set-up pitcher (a pitcher who throws while the closer is still warming up, also the backup closer), 2 long relief pitchers (1st inning through 4th inning backup), and 3 middle relief pitchers (5th inning through early 8th inning backup). The starting pitchers are the pitchers that start pitching in the 1st inning. The pitching rotation is the order of determining what starter will start. The rest of the pitchers make up the bullpen.

Five pitchers are used in a starting rotation for baseball teams. Sometimes in the post-season teams will use a rotation consisting of their best three or four pitchers only, to maximize their chances of winning a series.
