ROTTERDAM, Netherlands (AP) Second-seeded Marin Cilic of Croatia reached the World Tennis Tournament quarterfinals on Wednesday with a 7-6 (2), 7-6 (7) second-round win against Gilles Muller of Luxembourg.
Neither player faced a break-point in the first set, but Muller saved five in the second.
Cilic had two match points at 6-4 in the tiebreak, but then saved a set point at 7-6 down as Muller fought back strongly.
