     In October, 1961, at Crowley Field in Cincinnati Ohio, an old deaf gentleman named William E. Hoy stood

up to throw the first ball of the World Series (世界职业棒球大赛). Most people at Crowley Field on that day

probably did not remember Hoy because he had retired from professional baseball 58 years earlier in 1903.

However, he had been an outstanding player and the deaf people still talk about him and his years in baseball.

     William E. Hoy was born in Houckstown Ohio on May 23, 1862. He became deaf when he was two years

old. He attended the Columbus Ohio School for the deaf. After graduation he started playing baseball while

working as a shoemaker.

     Hoy began playing professional baseball in 1886 for Oshkosh (Wisconsin) of the Northwestern League. In

1888 he started as an outfielder (外场手) with the old Washington Senators. His small figure and speed made

him an outstanding base runner. He was very good at stealing bases during his career. In the 1888 major league

season,he stole 82 bases. He was also the Senators' leading hitter in 1888. Hoy was clever and he threw right-

handed and batted left-handed. On June 19, 1889, he threw out (射杀出局) three batters (击球手) at the plate

from his outfield position.

     The arm signals used by judges today to show balls and strikes began because of Hoy. The judge lifted his

right arm to show that the pitch was a strike and his left arm to signal that it was a ball.

     For many years people talked about Hoy's last ball game in 1903. He was playing for Los Angeles of the

Pacific Coast Winter League. It was a memorable game because Hoy hit a wonderful ball which won the game.

It was a very foggy day and therefore very hard to see the ball. In the ninth inning (棒球的一局) with two men

out, Hoy managed to catch a fly ball to make the third out in spite of the fog. Los Angeles defeated their

opposition and won the game.

     After he retired, Hoy stayed busy. He ran a dairy farm near Cincinnati for 20 years. He also became a public

speaker and traveled giving speeches. Until a few years before his death he took 4-10-mile walks several

mornings a week. On December 15, 1961, William Hoy died at the age of 99.
