　　Born on a farm in 1876.Mordecai Brown couldn't have imagined his life as a Major League Baseball pitcher（投手）.When he helped his parents at age 5, his right hand accidentally was caught in a corn harvester, losing parts of two fingers or three fingers left, However, his disabled hand did not keep him from doing what other boys of his age were doing, like playing baseball.

　　While working as a coal miner in his twenties, Mordecai joined a baseball team made up of fellow coal miners.In 1898, the team's pitcher injured his arm.The manager ordered Mordecai to act as the pitcher.Mordecai shook his head and held up his right hand as a reminder.But the manager didn't care."Since you have the best arm on the team, you will have to pitch."Finally, his team won the game nine to three.

　　In 1903, Mordecai Brown broke into Major League Baseball when he signed with the St.Louis Cardinals.Only a year later, the management of the Cardinals decided that Mordecai's disability would keep him from ever becoming a star pitcher.They traded him to the Chicago Cubs

　　On a sunny October afternoon in 1908, thousands of people went to New York City's Polo Grounds to see the New York Giants and the Chicago Cubs battle.Mordecai was not the pitcher at first. He watched as the chosen starter faced the batters（击球员）for the New York Giants.Soon, the batters were filling the bases.

　　Then, Mordecai was asked to be the pitcher.It seemed that the unfavorable condition didn't affect him.He held the ball with his three fingers firmly and let it go. Strike one! Strike two! Strike three! The batter was out.And soon, the game was over.The Cubs beat the Giants, four to two.

　　Mordecai went on to pitch, winning one game after another, and retired after the 1916 season.In 1949, Mordecai Peter entered the National Baseball Hall of fame in New York, earning him a well-deserved place in baseball history.
