Maria Kirilenko among first-round winners Tuesday at PTT Pattaya Open Maria Kirilenko, shown in a 2011 file photo, was among first-round winners Thursday at the PTT Pattaya Open WTA tournament in Thailand. 2-seeded Maria Kirilenko won Tuesday but top-seeded Ana Ivanovic was among players whose matches were delayed by rain at the WTA tournament in Thailand. Kirilenko defeated Akgul Amanmuradova 6-3, 7-5 in a tough 2-hour, first-round match at the PTT Pattaya Open. Kirilenko won about two-thirds of the points on serve and dropped serve only once. She also had a pair of breaks in each set while advancing. Ivanovic was at 1-2 and about to serve the fourth game of the third set when play was suspended for the day because of rain. There had been a lengthy delay because of the weather earlier. Two other first-round matches will also need to be completed Wednesday. 4-seeded Sorana Cirstea stopped Bethanie Mattek-Sands 6-1, 6-3 behind six breaks and fifth-seeded Sabine Lisicki was a 6-2, 6-3 winner over Tatjana Malek in just 60 minutes. Also No. 8-seeded Heather Watson advanced when, with Watson ahead 6-1, 3-0, Timea Babos retired. Other players moving into the second round included Kimiko Date-Krumm, Nina Bratchikova, Anastasija Sevastova, Anastasia Rodionova and local wild-card entrant Luksika Kumkhum.
