In the first round of the US Open, Alison (WTA-55) lost to American qualifier Jessica Pegula (WTA-260).
Lacking match rhythm since her injury and retirement in New Haven, Alison could not impose her game. The American, in confidence after three qualifying matches, took the opportunity and won in two sets: 7-5 and 6-3.
Alison (WTA D-123) will also play doubles with the Australian Daria Gavrilova (WTA D-169). They will meet fourth seeds Casey Dellacqua (WTA D-10) from Australia and Yaroslava Shvedova (WTA D-15) from Kazachstan in the first round.
