Haynes was an above average hitting pitcher, posting a career .213 batting average (111-for-521) with 48 runs, 1 home run and 39 RBI. Defensively, he was better than average, recording a .966 fielding percentage which was 9 points higher than the league average at his position.
He began his pro career in 1937, and made his MLB debut on April 24, 1939, at Fenway Park. Coming into the game in the eighth inning with one out and Washington leading the Boston Red Sox 9–7, he allowed Boston to tie the score in the bottom of the ninth, but held the Red Sox off the scoreboard in the tenth after the Senators had forged ahead in the top of that frame. Haynes was credited with the 10–9 triumph in his first major-league appearance.[1]
After two years with Washington, however, Haynes sported a poor 11–18 record and 5.67 earned-run average. Senators owner Griffith sold Haynes' contract to the Chicago White Sox on January 4, 1941.
Of Haynes' 379 MLB appearances, 218 came with the White Sox, where he won 55 of 98 decisions (.561) and posted a solid 3.14 ERA. He was named to the 1948American LeagueAll-Star team (although he did not appear in the game itself)[2] and led the league in games pitched (40) and games finished (35) in 1942 and in earned run average (2.42) in 1947.
After the 1948 season, Haynes, Ed Klieman, and Eddie Robinson were sent to the Senators in exchange for Mickey Vernon and Early Wynn.[3] He was ineffective, going only 10–21 with a 5.42 ERA in 112 games in his second stint with the Senators, which ended on October 7, 1952, when he was released.
Coach and executive
As a member of the Griffith family whose wife inherited 26 percent of the franchise's stock in 1955,[4] Haynes remained in the Washington organization after his playing career ended.
