Canada's Victoria Mboko's U.S. Open debut ended early with a 6-3, 6-2 loss to Barbora Krejcikova of the Czech Republic in a women's first-round singles match Monday.

Mboko was playing her first match since claiming the National Bank Open title in Montreal earlier this month.

The rising star from Toronto, who turns 19 on Tuesday, arrived at Flushing Meadows the women's 22nd seed.

The Canadian drew a formidable first-round opponent as Krejcikova is a two-time Grand Slam champion and won the Wimbledon women's title last year.

The Czech, a former world No. 2, opened with a break and cruised to victory in one hour 23 minutes.
