Kanepi began play Saturday with a 7-6 (8-6), 6-4 straight-set win over Jamie Hamilton of the United States and then posted a 6-2, 7-5 victory of China's Peng Shuai in the finals.
Peng beat Switzerland's Romina Oprandi in their Saturday semifinal match 6-4, 2-6, 6-4, but appeared to fade against Kanepi.
The semis and finals were played on the same day due to rain earlier in the week.
