Skipper Mahela Jayawardene smashed his 24th Test century and shared two century stands with Kumar Sangakkara and Thilan Samaraweera to help Sri Lanka stretch their lead over Bangladesh to 406 in the opening Test on Sunday. Jayawardene was unbeaten on 129 as Thilan Samaraweera followed his first innings 90 with 62 in the second before he was bowled by Mashrafe Mortaza, a dismissal that prompted the umpires to call off the third day's play for bad light. Their 138-run stand came after Sangakkara had recorded his 27th Test fifty. His was the only wicket to fall in the session, caught behind by keeper Mushfiqur Rahim off Mehrab Hossain for 67. Sri Lanka reached 291-4 at the close thanks to another healthy partnership of 135 runs built by Jayawardene and Sangakkara after the visitors' second innings had got off to a terrible start. Malinda Warnapura was trapped lbw for eight by paceman Mahbubul Alam and Mortaza uprooted the stumps of Michael Vandort on six to leave Sri Lanka reeling at 18-2. Earlier in the morning, Muttiah Muralitharan wasted little time in ending Bangladesh's first innings when he snapped up his sixth wicket to bowl the home side out for 178. After fog delayed play for 30 minutes, Bangladesh resumed on 177-9 but was dismissed on the final ball of the first over when Warnapura caught Alam at forward short-leg for a duck. Muralitharan had completed his 66th five-wicket haul in Tests on the second day and finished with figures of 6-49 after Sri Lanka made 293 in its first innings. The match will have a break on Monday for a national election in Bangladesh and the fourth day's play will be held on Tuesday. Duminy hits maiden ton J.P Duminy followed his heroics in Perth with a magnificent 166 that helped South Africa take a 61-run first innings lead over host Australia on the third day of the second Test at the Melbourne Cricket Ground Sunday. From a precarious position of 198-7, Duminy lifted South Africa by adding 67 with Paul Haris (39) and a stunning 180 with fast bowler Sale Steyn who cracked a career-best 76. The late order fightback helped South Africa tally 459. In the process Duminy not only belted his first Test hundred but also exhibited South Africa's fighting spirit and prowess. Scores: Australia 394 & 4-0. South Africa 459 (Duminy 166, Steyn 76, Smith 62, Siddle 4
