| "I was not good enough," Swiss Wawrinka, playing his first 
				match since losing to Roger Federer in the Australian Open 
				semi-finals, said. "I started well but it was a tough match. It 
				was his day."
 The 24-year-old Dzumhur, making his debut at the Dubai 
				tournament, recovered from losing the first three games to 
				outplay the second seed and three-times grand slam champion.
 
 He will next play Spain's Marcel Granollers next.
 
 Top seed and world number one Andy Murray returns to action for 
				the first time since his early defeat in Australia when he faces 
				Tunisia's Malek Jaziri later on Tuesday.
