NEW YORK (Reuters) - After an opening match nailbiter Angelique Kerber sailed drama free into the third round of the U.S. Open on Thursday, brushing past Anhelina Kalinina 6-3 6-2 to set up a rematch of former champions.

Kerber had appeared headed for an early Flushing Meadows exit until coming back from a set down to see off Dayana Yastremska 3-6 6-4 7-6 (3).
