Ajax leveled the score on the evening when Chasity Grant's finish went under Musovic's body, but the Swedish goalkeeper later made a superb save from Leuchter to end any prospect of a dramatic late comeback.
Hayes had rested several players, including England star Lauren James, ahead of Sunday's League Cup final against Arsenal at Molineux, where Chelsea will look to capture the first of that potential quartet of major honors this season.
