Jason Alias Heyward (born August 9, 1989), nicknamed "J-Hey" is an American professional baseball right fielder for the Chicago Cubs of Major League Baseball (MLB). Originally the Atlanta Braves' first-round selection in the 2007 MLB draft from Henry County High School in Georgia, he began his minor league career at age 17. Heyward soon became one of the top-rated prospects in all of baseball for batting, speed, and defense, and debuted in MLB as Atlanta's starting right fielder on Opening Day 2010. There, he played until being traded to the St. Louis Cardinals after the 2014 season. Standing 6 feet 5 inches (1.96 m) tall and weighing 245 pounds (111 kg), he throws and bats left-handed. He has worn uniform No. 22 throughout his major league career in honor of a high school friend and teammate who died in a traffic collision.
