DELRAY BEACH - Croatia's Marin Cilic defeated former champion Kevin Anderson of South Africa in three sets on Sunday to win the ATP Delray Beach Open and notch his second title in three weeks. Cilic , seeded seventh, defeated fourth-seeded Anderson 7-6 (8/6), 6-7 (7/9), 6-4 to notch his ATP Tour leading 18th match victory of the year. He added another title to the Zagreb trophy he claimed earlier this month. He also reached the final in Rotterdam last week. Cilic needed three hours and eight minutes to claim the victory, which was especially sweet after Saturday's rain delay saw him start late and labor until the early hours to beat second-seeded John Isner in the semi-finals. "It feels awesome, especially after waiting for a long time last night and finishing after 1 am," Cilic said.
