Sachin Tendulkar hit his career’s 50th Test century even as India headed towards a massive defeat against South Africa at the SuperSport Park in Centurion on Sunday. ScoreIndia were trailing by 30 runs with two wickets remaining when play was called off owing to bad weather of Day Four. Chasing South Africa’s a first innings lead of 484, India were 454/8 at stumps with Sachin Tendulkar (107) and S Sreesanth (7) at the crease.This was before Tendulkar along with skipper Mahendra Singh Dhoni tried hard to resurrect the India innings that had been rendered lifeless in the face of devastating spells by the Protea pacemen.Tendulkar went on to complete his much-desired half-century of Test tons with Dhoni aptly supporting him.No sooner did Tendulkar achieve the target that Dhoni fell, giving an impression that he was only in the middle to help Sachin’s cause.A Dale Steyn delivery that climbed on him had Dhoni fend for cover and in the process he gave away an edge to Mark Boucher behind the stumps. He was out for 90.Post his dismissal Paul Harris accounted for Harbhajan Singh’s wicket to fast track India’s loss. The game could have got over in minutes, but bad weather stopped play and soon stumps were called.In the morning, night watchman Ishant Sharma fell to Steyn on 23 and later Morne Morkel accounted for Rahul Dravid’s wicket on 43.VVS Laxman, who looked to form a partnership with Tendulkar, too could not stay at the crease for long and was sent back by Lonwabo Tsotsobe on 8.advertisementJacques Kallis, who had scored his maiden double ton on Saturday, claimed Suresh Raina on 5.On Saturday, the visitors had lost both their openers with Virender Sehwag sent back by Harris on 63 and Gautam Gambhir falling to Steyn on 80.
