CHENNAI - Defending champion and top seed Stanislas Wawrinka cruised into the Chennai Open final with a straight-sets win over fourth seed David Goffin Saturday. The Swiss world number four, who has not dropped a set in the tournament, gave the 22nd-ranked Goffin a 90-minute masterclass with a 7-5, 6-3 win. Wawrinka's opponent in Sunday's final will be Slovenian qualifier Aljaz Bedene, who continued his amazing seed-slaying run with an three-set victory over third seed Roberto Bautista-Agut. The 156th-ranked Bedene survived four match points and himself wasted one before edging out the number 15 Spaniard 3-6, 6-3, 7-6 (10/8) in two hours and 42 minutes. Wawrinka said he looked forward to playing the final against a man who defeated him in the quarter-finals here two years ago.
