The 20-year-old American forward has extended his stay at the Stadium of Light until 2019.
Gooch, 20, originally joined Sunderland’s academy in June 2012 after enjoying a successful trial and has since risen through the ranks to establish himself as one of the club’s top prospects.
The California native, who holds a British passport through his Colchester-born father, made a stellar start to the season with the Under-21s, recording three goals and an assist in their opening three games to win the Under-21 Premier League Player of the Month award for August, and was rewarded for his efforts with a promotion to the senior squad.
He subsequently made his first-team debut in the Capital One Cup victory over Exeter City as a second-half substitute and has since spent time out on loan at League One side Doncaster Rovers, making seven starts in 10 appearances.
The former US youth international’s stay the Keepmoat Stadium was cut cruelly short in mid-March by a nagging ankle problem, but there should be more senior opportunities available to him at the Stadium of Light next term once he is back up to full speed.
Having been surprisingly overlooked for the US Under-23 team's Olympic qualifying campaign, the promising attacker has flown somewhat under the radar compared to some of America’s other top European-based prospects, but there is little doubt that he will be on Jurgen Klinsmann’s radar if he starts making his mark in the North East.
