American tennis player Danielle Collins sarcastically blew a kiss towards the crowd in the Kia Arena after defeating her Australian opponent Destanee Aiava at the Australian Open on Thursday. The crowd, backing Aiava, kept booing Collins throughout the match. Collins also asked a spectator to shut up while serving in second set. The American beat Aiava 7-6 (7-4), 4-6, 6-2.
