Guernsey's Heather Watson has been drawn against 21st seed
in the first round of the US Open.
The British number two has seen her ranking slip to 77 after struggling for form following her recovery from glandular fever.
Watson is working with coach Jeremy Bates for the hard court season after
parting company with Mauricio Hadad.
The 21-year-old has never faced Romania's Halep - who has won three tournaments this season - before.
Watson is still seeking her first win at Flushing Meadows after first-round defeats in 2011 and 2012.
