Mason, OH – Fifth seed Tomas Berdych cruised in the second round at the $2.825 million Western & Southern Open.
The Czech topped Taiwanese Yen Hsun-Lu 6-3, 6-4 and will take on the winner of Milos Raonic and Marcos Baghdatis in the third round.
Tenth seed Mardy Fish was an easy winner, while his fellow American Andy Roddick came up an opening-round loser.
The two-time Cincinnati runner-up Fish fired 11 aces in blitzing Spanish left- hander Feliciano Lopez 6-2, 6-3, while the 16th-seeded Roddick succumbed to French lucky-loser Jeremy Chardy 7-6 (7-4), 6-3 on the hardcourts at the Lindner Family Tennis Center. Roddick required the services of a trainer while leading 2-1 in the second set for an apparent back problem.
Fish reached finals here in 2003 and 2010, while Roddick captured Cincinnati titles in 2003 and 2006 and was the runner-up in 2005.
Fourteenth-seeded Japanese Kei Nishikori avoided a first-round upset by whipping Spaniard Marcel Granollers 6-1, 6-2, while former Australian Open runner-up Marcos Baghdatis of Cyprus upended 11th-seeded Colombian Alejandro Falla 6-4, 6-1 on Day 3.
A Tuesday second-round result saw Aussie Bernard Tomic take out American wild card Brian Baker 6-4, 6-3.
American wild card Sam Querrey reached the second round with a 4-6, 6-2, 6-4 victory over struggling Austrian Jurgen Melzer. Querrey titled on a hardcourt in Los Angeles last month.
Querrey's second-round opponent will be Olympic gold medalist and Wimbledon runner-up Andy Murray, this week's third seed and defending champion. The two- time Cincy titlist Murray beat Novak Djokovic in last year's marquee finale here.
Raonic topped Richard Gasquet, who was runner-up to Djoka at last week's Canadian Masters in Toronto, 7-6 (7-4), 6-3.
In other opening-round play, German Tommy Haas saved a match point before sneaking past fellow former top-five star David Nalbandian of Argentina 6-7 (0-7), 7-6 (7-4), 6-3 in 3 hours, 22 minutes; Czech Radek Stepanek doused Spaniard Albert Ramos 6-2, 6-2; Argentine Carlos Berlocq topped Colombian fellow South American Santiago Giraldo 7-5, 6-3; and Russian Alex Bogomolov Jr. dropped Finnish veteran Jarkko Nieminen 6-4, 6-3.
This week's top seed is Wimbledon champion and Olympic silver medalist Roger Federer, who will open his latest Cincinnati stay against Bogomolov. The Swiss great captured this event in 2005, 2007, 2009 and 2010.
This seventh of nine ATP Masters tournaments will pay its 2012 champ $535,600.
