Fading light forced the suspension of the Australia-Switzerland Davis Cup World Group playoff on Sunday, with Lleyton Hewitt and Stanislas Wawrinka into the final set of the deciding match. Switzerland’s Wawrinka was two sets to one up and leading 5-3 in the fifth when the match referee decided it was too dark to continue. The two players will come back on Monday to complete the match, with Wawrinka leading 4-6, 6-4, 6-7 (7/9), 6-4, 5-3. World number three Roger Federer earlier levelled the best-of-five tie at 2-2 when he beat Bernard Tomic in four sets 6-2, 7-5, 3-6, 6-3. The winner of the tie will play in the top tier World Group in 2012, while the loser will be forced into regional qualifying. The experienced Hewitt will have to win his first serve when play resumes Monday just to stay in the encounter. Wawrinka struggled with injury and indifferent form in losing his opening singles match to Tomic on Friday, and then the doubles on Saturday.
