New York | World No. 1 Ash Barty has crashed out of the US Open with an erratic performance in which she blew a 5-2 lead in the deciding set to lose to unseeded American Shelby Rogers.
Barty had not dropped a set in the tournament but was sloppy from the start. She made 17 unforced errors in the first set and then three more when she held a 5-2 lead in the third that let Rogers back in. Rogers broke Barty twice in the third when Barty served for the match.
