GUADALAJARA, Mexico (Reuters) -Defending champion Magdalena Frech was sent packing from the Guadalajara Open after a 7-5 6-4 quarter-final defeat by 19-year-old Czech Nikola Bartunkova on Friday, while German sixth seed Tatjana Maria was knocked out by Elsa Jacquemot.
Bartunkova secured the win over Polish fourth seed Frech - who won the WTA 500 hardcourt tournament last year by beating Australia's Olivia Gadecki in straight sets in the final - in one hour and 38 minutes to advance to her first WTA semi-final.
