Novak Djokovic upset at Australian Open

MELBOURNE, Australia — Novak Djokovic’s bid for a fourth consecutive Australian Open title ended in a dramatic five-set quarterfinal loss to Stanislas Wawrinka that opens up the prospects of a new major champion.

No. 8-seeded Wawrinka lost 14 head-to-heads to Djokovic until a 2-6, 6-4, 6-2, 3-6, 9-7 win on Tuesday night put him into a semifinal that very few expected against No. 7 Tomas Berdych.
