A bowler is a person who bowls or delivers a ball to the batsman in the game of cricket. Unlike the pitcher in a game of baseball, a bowler delivers with a straight arm (see photo). A ball bowled with the elbow bent is a throw, and that is illegal. If the bowler bowls while not in the right part of the nonstriker's ground,[1] or bowls the ball out of the reach of the striking batter, that is also illegal. Illegal bowling gives the batting team 1 point, mostly can't get players out, and doesn't count toward the limit on the number of deliveries in the game.
A bowler who can also bat well, is called an all rounder. There are different types of bowler, and a cricket team will usually have a mix of different types.
