Hazewood was a first round pick, and the nineteenth player selected overall, by Baltimore in 1977. He spent the majority of his career in the minors, playing for the Charlotte Orioles (Class AA) in the 1980s. He was known as a power hitter who struck out frequently and had difficulty hitting a curveball. Hazewood had more strikeouts than hits in every single season he played, at every level, both major and minor league.
He made his major league debut in 1980, appearing in six games and going hitless in five plate appearances with four strikeouts.
Hazewood died from cancer at his home in South Sacramento, California on July 28, 2013. He was 53 years old.
