The former world No.17 was eliminated from a tournament in Santo Domingo in straight sets 6-2 6-2 by Andres Andrade but refused to shake the Ecuadorian's hand post-match.
With Andrade making the final against Bosnia-Herzegovina's Damir Dzumhur, Tomic returned to the venue, wearing a cap and glasses.

The Australian reportedly even moved around the venue between games to ensure he was always at the same end as Andrade.
Following a flare-up between Dzumhur and the umpire, Tomic became involved, talking to the umpire from the court boundary.
Andrade complained to the umpire about Tomic's behaviour, with the 31-year-old confronted by tournament officials early in the second set and asked to leave, with the crowd cheering the decision.
Dzumhur, reportedly a friend of Tomic, won the final 6-4 6-4.Â
Outside the world'd top 100 since 2019, the one-time wonder-kid has slid down the rankings to 250.
He was also embroiled in drama at a tournament in Arkansas in June when he quit mid-match after getting into an argument with his girlfriend in the stands.
