William Barney McCosky (April 11, 1917 – September 6, 1996) was an American outfielder in Major League Baseball.

"[1] McCosky attended Southwestern High School in Detroit, where he was All-City and captain in both baseball and basketball.

[2] In 11 major league seasons, McCosky was a .312 hitter with 24 home runs and 397 RBIs in 1,170 games played.

A fine outfielder with a strong throwing arm, he collected a .984 fielding average with only 41 errors in 2579 chances.

He started 145 games in center field and hit for a .311 batting average — trailing only Hank Greenberg and his boyhood hero, Charlie Gehringer, among the Tigers' starters.

In December 1942, McCosky joined the United States Navy during World War II.

[4] McCosky lost three years in the prime of his career (at ages 26–28) to military service during World War II.

In his autobiography, Kell recalled being shocked that the Tigers would trade a "legitimate star" and "hometown boy" like McCosky for an "unknown third baseman."

"[6] Playing for manager Connie Mack, McCosky broke out of his early season slump and hit .354 for the A's.

On April 26, 1951, McCosky broke up a no-hitter bid of Washington Senators Connie Marrero with a home run.

After his baseball career ended, he operated Barney McCosky's party store on Joy Road between Greenfield and Southfield in Detroit from 1953 to 1963.

He then worked as an automobile salesman at Les Stanford Chevrolet in Dearborn, Michigan, until he retired in 1982.
