UMAG, Croatia — Croatia's Borna Coric beat Marcel Granollers 6-3, 6-3 in hot and humid conditions on Tuesday to reach the second round of the Croatia Open.
Seventh-seeded Coric felt at home with the weather, converting four out of 11 break points and scoring 35 winners to defeat his Spanish opponent.
"Conditions were very tough, but I like to play when it's like this, when the ball and court is slow, so I have more time," Coric said.
He next faces Britain's Aljaz Bedene.
Sixth-seeded Phillip Kohlschreiber of Germany also advanced after saving five break points to beat Santiago Giraldo of Colombia 6-3, 6-2.
