Smyczek, Chardy reach quarterfinals at Delray

DELRAY BEACH, Fla. (AP) Fifth-seeded Frenchman Jeremy Chardy and American Tim Smyczek fought through swirling winds to reach the quarterfinals of the Delray Beach Open on Thursday.

Chardy joined fourth-seeded Bulgarian Grigor Dimitrov of Bulgaria as one of only two seeded players left.

Chardy trailed 2-0 to 19-year-old Noah Rubin of New York, before winning 12 of the next 16 games for a 6-4, 6-2 victory. He will play either qualifier John-Patrick Smith of Australia or Argentine Juan Martin del Potro who is playing his first ATP tournament in 11 months due to wrist surgery.

Smyczek had a more dramatic comeback against fellow American Donald Young. Down 6-1, 3-1, Smyczek rallied for a 1-6, 7-6 (2), 6-2 win. In the quarters, he will face one of two Americans, Austin Krajicek or Sam Querrey.
