Alexander Blockx celebrates his hard-fought quarter-final win Friday at the Cap Cana Challenger.
By ATP Staff
Under a punishing Caribbean sun in sweltering humidity, Alexander Blockx dug deep Friday to reach the semi-finals at the ATP Challenger 175 event in Cap Cana, Dominican Republic.
The reigning Next Gen ATP Finals runner-up rallied past Coleman Wong 4-6, 7-5, 6-3 in a bruising two-hour, 30-minute battle that tested both players to their physical limits. Blockx, who played a three-hour marathon less than 24 hours before, celebrated his quarter-final victory by falling to the ground in relief.
“This morning when I woke up I was like, ‘It cannot possibly be any more difficult than yesterday’, but I think this was one of my toughest matches I’ve ever played physically,” said the 20-year-old. “The first set I wasn’t feeling well with the heat after playing three hours yesterday. The second set was so long, every point was so long. I just kept fighting.”
Blockx will NEVER back down 😱
