British number three Naomi Broady began her clay-court season with a heavy defeat by American Madison Brengle at the Prague Open.
Brengle, ranked nine places higher than Broady at 71 in the world, won 6-2 6-0 in 52 minutes.
Broady had her serve broken five times and did not earn a single break point.
The 26-year-old from Stockport reached a career-high 76 in the rankings last month after her first WTA semi-final appearance in Kuala Lumpur.
