Improving Konjuh can test Carla

From midday
Olympic tennis competitions have a habit of throwing up more than the odd surprise result and Ana Konjuh could make life difficult for second-round opponent Carla Suarez Navarro in Rio today.

Take away Serena Williams, whom Suarez Navarro idolises but struggles to beat, and the Spaniard becomes a serious title contender.

But while the Canary Islander, a 2-6 6-1 6-2 victor against Ana Ivanovic in her Rio opener, may be suited to conditions in Brazil and is so consistent that she deserves to be on the short-list for medals, Konjuh possesses so much talent that an upset cannot be ruled out.
