JOHANNESBURG, South Africa, Feb. 5 (UPI) -- Top-seeded Jo-Wilfried Tsonga led Thursday's winners at the South African Tennis Open with an easy 6-4, 6-1 win over Uzbekistan's Denis Istomin.
He started his second-round rout by breaking Istomin twice in the opening set and cruised into Friday's quarterfinals at the inaugural tournament in Johannesburg.
