Dominic Thiem and Stan Wawrinka will make their highly anticipated returns in Marbella on Tuesday at the AnyTech365 Andalucia Open, an ATP Challenger Tour event.

Wawrinka will be the first star who returns, as he faces Swede Elias Ymer in the second match on Estadio Manolo Santana. 

The Swiss, who celebrated his 37th birthday on Monday, underwent two foot surgeries last year. The former World No. 3 has not competed since Doha just more than one year ago.

Thiem will make his comeback against Pedro Cachin of Argentina, in the match following Wawrinka’s against Ymer (NB 1:30 p.m. local).

The Austrian suffered a right wrist injury while competing in Mallorca last June. Unlike Wawrinka, Thiem’s injury did not require surgery.
