The oldest brother in a family of 14, and one of three Kocsis brothers in the Michigan Golf Hall of Fame (Chuck and Sam), Emerick was the first to caddie and learn the game at Phoenix Country Club, a Donald Ross design that later became Rogell Golf Course, which has been closed since 2013.
He eventually became an assistant golf professional at the Phoenix while his more famous brother Chuck and Sam remained amateurs. He introduced the game to his brothers and had quite an accomplished playing career.
At age 20 in 1928, he defeated Oakland Hills professional and fellow Michigan Golf Hall of Fame member Al Watrous, 2 and 1 in the semifinals, and went on to win his first of two Michigan PGA Professional Championships. He also won the 1940 Michigan Open Championship topping the likes of Watrous, two-time defending champion Marvin Stahl, Chick Harbert and his brothers.
He took his game on the national stage, too, playing in the PGA Championship and U.S. Open multiple times. In the 1939 PGA, then conducted in match play with qualifying rounds to determine the bracket, he was co-medalist in qualifying with Ben Hogan, Ky Laffoon and Dutch Harrison. He reached the quarterfinals before falling to Byron Nelson.
He served in World War II and was wounded in action. He died in 1995 at the age of 85.
