Brit Jack Draper retires after collapsing on ATP Tour debut
Nineteen-year-old Jack Draper was forced to retire during his ATP Tour debut at the Miami Open.
The Brit collapsed when opponent Mikhail Kukushkin was serving for set point after a gruelling 75-minute first set in the blistering Florida heat.
Up until that point though, Draper had kept pace with his more experienced opponent and came from a break down to level but the heat proved too much for the Londoner.
Draper was given a wildcard entry into the tournament after some good recent form on the ITF and Challenger circuits.
