In 2012, Cochran-Siegle won the Nor-Am downhill and super-G titles, and he also won two gold medals at the Junior World Championships, in downhill and combined. However his progress was interrupted in 2013 when he suffered injuries to his anterior crcuiate and medial collateral ligaments during the downhill portion of the combined at the World Championships. He returned to competition in the 2014 season, winning the overall Nor-Am Cup; he was second in the downhill standings and third in the super-G and giant slalom standings.
