Aussie Birrell beaten in Guadalajara opening round

Australia's Kimberly Birrell has missed the chance to take on fourth seed Caroline Garcia in round two of the WTA 500 event in Guadalajara, Mexico.

A day after compatriot Olivia Radecki set up a clash with second-seeded American Danielle Collins, 26-year-old Birrell was beaten 6-4 7-6 (7-4) by Ena Shibahara.

Birrell, the world No.150, capitalised on four of her nine break point opportunities during the one hour 41-minute contest, while her Japanese opponent broke five times from as many chances.

Elsewhere on Tuesday, Martina Trevisan settled a score against eighth-seeded Caroline Dolehide with a 6-3 6-2 win.

Trevisan, who lost to Dolehide a year ago in the Guadalajara quarter-finals, will next play local favourite Renata Zarazua.

"Today I came to the court with a lot of energy," Trevisan said.

"For me maybe it was revenge and tomorrow I must be ready for Renata. I have played twice against her this year. I know her very well."

Marie Bouzkova beat Alexandra Eala 6-2 6-2 to advance to a second-round match against Lucrezia Stefanini, who ousted Ana Sofía Sanchez 6-0 3-6 6-2.

The sixth-seeded Bouzkova made the semis in Guadalajara a year ago before losing to eventual champion Maria Sakkari.

Ashlyn Krueger defeated Tatjana Maria 7-5 6-2 and will next face Magdalena Frech, a 6-4 6-4 winner over Emina Bektas.
