The US Open has confirmed 14 of the pairings that will compete for $1m (£749,077) in next month's controversial mixed doubles event.
Organisers were heavily criticised in February after announcing that the mixed doubles competition would be a standalone event on 19-20 August - before the hard court Grand Slam begins on 24 August.
British number one Emma Raducanu and five-time Grand Slam champion Carlos Alcaraz are one of six wildcard pairings, with eight teams gaining direct entry.
The US Open said a a further two wildcard entries will be announced at a later date.
