As Sports Illustrated's Jon Wertheim reports, Dominic Thiem has been playing a lot of tennis during the shutdown caused by the coronavirus pandemic. Thiem recently came out in support of a rule change wherein there would be a third set "super tiebreak" to settle matches. The reasoning for the change would be to shorten matches in a time where many players have not been able to keep up with competition due to the tennis layoff. Wertheim shares more on Thiem and the proposed change.
