From a teenage prodigy to owner of the third-worst losing streak in the Open era - Donald Young has encountered the full gamut of tennis experiences.
Once regarded as the next big thing in American tennis, Young is still struggling to live up to those expectations as he begins the new year at next week's Heineken Open.
The 24-year-old feels ready to find the form he showed when climbing to world No38 in 2011 and that search will start at qualifying in Auckland, an event he sees as perfect preparation for the Australian Open.
The opening Grand Slam of the season is unlikely to produce an American champion from the men's field, which would extend a drought dating back to Andy Roddick's win at the 2003 US Open.
Young was meant to be the man to snap that streak. Once the No1 junior player in the world and anointed by John McEnroe as the hottest property in tennis, he signed a professional contract with marketing group IMG at 15 but struggled in Futures and Challenger events while receiving wildcards into various ATP tournaments.
