Casper Ruud to face Yoshihito Nishioka in Korea Open quarterfinals

Casper Ruud entered the quarterfinals of the Korea Open

Casper Ruud booked his place in the quarterfinals of the Korea Open by defeating Nicolas Jarry 6-2, 3-6, 6-3. The Norwegian, who received a bye in the first round, started the match strong and got two breaks to take a 4-0 lead in the opening set, which he eventually won 6-2.

But Jarry fought back in the second set and broke Ruud in the fourth game to take a 3-1 lead. The break turned out to be decisive as the Chilean won the set 6-3 to force the match into a decider.

The final set saw both players dominating their service games until the World No. 2 made the decisive break in the sixth game. Jarry then fought hard and saved three match points but the 23-year-old won the final set 6-3 to book his place in the quarterfinals.

Ruud will next take on Japan's Yoshihito Nishioka, who beat compatriot Taro Daniel 6-2, 6-4. This will be the second career meeting between the pair, following their second round clash in last year's Madrid Open which Ruud won 6-1, 6-2.

The winner of the match will face either Mackenzie McDonald or Aleksandar Kovacevic in the semifinals of the Korea Open.
