A crazy 24 hours from Tashkent to Antwerp, and a marathon win in a third-set tiebreak in the first round of qualifying, caught up with Canadian teenager Félix Auger-Aliassime Monday.
The 18-year-old retired, down 2-6, 0-3 to veteran Sergiy Stakhovsky in the final round.
The spirit was willing, but the legs were toast after running on adrenaline Sunday.
Auger-Aliassime had the trainer come out to look at what appeared to be a foot issue, then stopped.
Stakhovsky stayed around for quite awhile to talk to the youngster, as he sat there disappointed following the match.
