A single break in each set was enough for Janko Tipsarevic to move into the quarterfinals of Bangkok, seeing off a spirited Hiroki Moriya 6-4 6-4. Tipsarevic was dominant on serve throughout the match, serving three aces and dropping just three points on his first serve, not facing a single break point.
Moriya, outside the top 200, showed ability way above his ranking as he stayed close with No. 9 Tipsarevic holding serve all the way until 4-4. After recovering to deuce from 0-40, it looked like Moriya would escape with the hold but the Serb eventually took advantage on his fifth break point opportunity to move 5-4 ahead and serve for the set.
After serving the set out to love, the momentum would keep with Tipsarevic after he killed off any lingering doubts with a break in the first game of the second set as Moriya lost 4 consecutive points from 40-15 up. It would be enough for Tipsarevic to hold on until the end but he missed out on opportunities in latter games to add a bit of gloss to score, missing break points at 2-0 and 4-2. Tipsarevic will face either Fernando Verdasco or Donald Young in the quarter finals.
Jarkko Nieminen is also through to the next round, where he will face either Milos Raonic or Ivo Karlovic, after a 7-6(1) 6-2 win against Philipp Petzschner. Nieminen made much more work of the match than he should as he twice dropped his serve when up a break, including at 5-3 as he attempted to serve out the set. After a convincing love hold to force the tie break, it seemed like Petzschner had the upper hand. However, the German played a shocking tiebreak, losing all four points on serve and going down very easily.
After two break points went begging for Nieminen in the opening game of the second set, the Finn would then fall apart on his own serve handing over the break himself to fall to an 0-2 deficit. After finally getting into a promising position in the set it would all go wrong for Petzschner as he could not hold serve any more. Breaks followed in each of the three service games to follow as Nieminen won five games in a row to serve for the set and match. Petzschner was unable to break even with three break points in this final game to extend the match as Nieminen took five points in a row to seal the victory.
