No. 3 seed Jurgen Melzer of Austria, No. 4 Ernests Gulbis of Latvia and No. 6 Thiemo de Bakker of the Netherlands headline Wednesday’s second-round action at the PTT Thailand Open.

In the first match on, Frenchman Florent Serra looks for his second win this year against Spaniard Guillermo Garcia-Lopez. Serra won in straight sets in the quarter-finals in Casablanca in April en route to the semi-finals. Garcia-Lopez is trying to reach his fourth ATP World Tour quarter-final or better this season.

In the second match, Melzer takes a 2-0 advantage against top Israeli Dudi Sela. The Austrian, who reached the semi-finals here last year, won both of his meetings this year against Sela, in the first round at Roland Garros, and in a recent Davis Cup tie in Israel. Melzer is compiling the best season of his career, ranked No. 13 with a 41-21 match record. He’s looking to advance to his 10th quarter-final or better this year. Sela reached the semi-finals in Chennai in January and the quarter-finals at Queen’s Club in June.

In the third match, Germans Benjamin Becker and Mischa Zverev square off in the final first-round match of the tournament. Both players are looking to reach their fourth ATP World Tour quarter-final (or better) this year. Becker, who was a finalist here in 2007 (l. to Tursunov), beat Zverev in the quarter-finals of Halle in June. Zverev was a special exempt into the tournament after getting to his first ATP World Tour final in Metz on Sunday (l. to Simon). He jumped from No. 155 to No. 115 in the South African Airways 2010 ATP Rankings.

In the first match of the evening session, Gulbis and veteran German Rainer Schuettler meet for the first time. Gulbis is one of the most improved players on the ATP World Tour this year, jumping from No. 90 at the end of last year to No. 25 coming into this week. He captured his first ATP World Tour title in Delray Beach in February and he’s been to the quarter-finals or better in five other tournaments. Schuettler was a semi-finalist at Queen’s and quarter-finalist in Los Angeles.

In the final match, 22-year-old de Bakker, another rising star who has climbed from No. 96 last year to No. 47, takes on Daniel Brands of Germany. De Bakker is looking to reach his fourth ATP World Tour quarter-final or better this year while Brands is trying to advance to his first quarter-final in 2010.
