After an injury-filled 2013 season, Amos returned to form in 2014. At the 2014 Prefontaine Classic, Amos set a meet record and world-leading time of 1:43.63. At the Herculis IAAF Diamond League, he again set a meet record and world leading mark of 1:42.45. Beating Rudisha for the 2nd time on the season, his performance was the fastest 800m race since the men's 800 m race. At the 2014 Commonwealth Games, Amos won the 800 meter gold medal in 1:45.18. In the tactical affair, Amos maneuvered out of a box to pass World Record holder David Rudisha in the last 50 meters.
