TOKYO -- Guillermo Garcia-Lopez of Spain ousted countryman Feliciano Lopez in the second round at the $1.1 million Japan Open Tennis Championships on Wednesday.
Garcia-Lopez, last week's winner of the Thailand Open, took a 7-6 (7-5), 6-4 decision over the sixth-seeded Lopez, who beat former U.S. Open champion Juan Martin del Potro in the opening round here.
In other second-round play, Radek Stepanek of the Czech Republic was up 5-7, 7-6 (9-7), 4-1 before Marco Chiudinelli of Switzerland retired with a lower back injury on Day 3.
Next up for Stepanek in the quarterfinals will be Finnish veteran Jarkko Nieminen, a 6-3, 7-6 (10-8) winner over Daniel Gimeno-Traver of Spain. Nieminen, who was last week's Bangkok runner-up to Garcia-Lopez, upended defending Tokyo champion Jo-Wilfried Tsonga in the first round.
Another second-round match saw Russian Dmitry Tursunov outlast Richard Gasquet of France, 7-6 (7-2), 1-6, 6-4, in a little over two hours.
World No. 1 superstar Rafael Nadal, who lost to his countryman Garcia-Lopez in a semifinal in Thailand last week, will be in action here on Thursday against Canadian qualifier Milos Raonic. Andy Roddick, seeded second, fourth-seeded Jurgen Melzer and fifth-seeded Gael Monfils are also slated for Thursday play.
