The tournament, which began in 2009, is not an official ATP event, but it has always attracted some of the sport's biggest names. Nadal has won it four times, and Djokovic won three straight from 2011-2013.

The top two seeds, Djokovic and Nadal, have earned byes to the semifinals. Chung will face Anderson in the first-round match, with the winner advancing to face Nadal in Friday's semifinals.

Chung lost his first two meetings against Anderson, the runner-up at the 2017 U.S. Open and 2018 Wimbledon.

Chung enjoyed the best season of his career in 2018, which included an appearance in the semifinals at the Australian Open in January.
