Spain's Pablo Carreno Busta secured his first career victory at the All England Club on Monday after Canada's Denis Shapovalov retired from their Wimbledon first-round match.
Shapovalov withdrew due to a left shoulder injury sustained when he collided with a courtside barrier late in the second-set tiebreak.
