Jansen and Harmer take South Africa closer to 2-0 sweep of India

South Africa ensured their first series win in India in 25 years by building on their lead for nearly five hours. While the declaration, setting India more than they have ever been set at home, seemed a touch conservative, the visitors went to stumps needing eight wickets on the final day to take away all 12 WTC points from this Test and consign India to their second whitewash at home in 12 months after 12 years of spotless series record.

As it often happens in such match situations, the same pitch that South Africa batted on, looking untroubled for 70.3 overs, began to look unplayable in the 15.5 India got to play. Marco Jansen didn't even bother with swing and seam, and began to bounce Yashasvi Jaiswal before getting him out on the cut shot. Simon Harmer, who has out-bowled the home spinners, continued his dream series with a dream offbreak to bowl KL Rahul through the gate, and came desperately close to getting B Sai Sudharsan out lbw.

The day began with curiosity around how much South Africa valued the 12 full points from this match vis-a-vis ensuring they give India no chance to threaten their series lead. Turns out they were in no mood for adventure. Especially as the ball started to turn more consistently in the first session of the fourth day than it had done at any point before. Ravindra Jadeja and Washington Sundar got long spells in. Jadeja got Ryan Rickelton caught at extra cover, but then India did what they have struggled to do all Test: get wickets on defensive shots. Jadeja beat Aiden Markram's outside edge and hit the off stump, Washington got one to bite at Temba Bavuma's glove and settle in the hands of backward short leg.

As three wickets fell for 18 runs, South Africa remained slightly cautious. Tristan Stubbs and Tony de Zorzi, though, managed to keep the threat of spin out with their sweeps and reverse sweeps. After Rishabh Pant missed a stumping off Stubbs, the No. 3 batter limited his options to just the sweeps whenever he wanted to force the pace.

Stubbs and de Zorzi added 101 for the fourth wicket, 41 of those in sweeps and reverse sweeps. Like Stubbs in the first innings, de Zorzi fell one short of a fifty, beaten on the sweep for a change. It was mid-afternoon and South Africa led by 466, but they still continued to bat at normal pace.

Only after the lunch break did Stubbs get a move-on to try to complete a Test hundred, but even this charge was not frenetic. The team management gave him all the time as he scored 32 from the last 19 balls he faced, taking the lead past the 542 that Australia attained in Nagpur in 2004. He slog-swept Jadeja to go from 88 to 94, but Jadeja slowed the ball down to beat a repeat attempt. Stubbs still was the highest run-getter in the series (163), and would need a big effort from someone in the final innings to be eclipsed.

That effort wasn't coming from the openers. India have done this to many a visiting side - just when everybody thought they had been too conservative with the declaration, the pitch would magically change its nature and wickets would start falling.

Something similar happened when Jansen ran in and started bowling short. In the first over itself, he had Jaiswal fending uncomfortably. One didn't pop up, the other landed just short of second slip. While Jaiswal managed to ramp him once, he fell to his favourite cut shot again. Since Jaiswal's debut, nobody has scored more Test runs with the cut off fast bowlers than his 291, but no one has got out as often as his seven times. Nobody has played as many false shots as he has on the cut to the fast bowler: 68. He averages 41.57 on the cut against fast bowlers, but has fallen to this shot four times in his last eight innings.

Rahul was more traditional in the route he took to fight for a draw. He scored just 6 off 30 balls, but the 30th was a bewitching dipping, drifting delivery, which had him playing well away from where he thought it would originally pitch. In panic, he turned his drive into a flick, but it wasn't enough to plug the gap created between his body and his bat. Harmer was again level with Jansen for most wickets in the series: 12.

Harmer came extremely close to taking the lead when he appealed for lbw against Sai Sudharsan. In all likelihood, the on-field call for not-out was down to an inside edge, but the replay showed the ball had hit the pad first. However, the ball tracking returned an umpire's call on impact, saving Sudharsan to fight another day.

India somehow survived the rest of the day but it looked like a wicket could fall anytime. South Africa now have six hours to take eight wickets because the light has consistently dipped by 4pm, not allowing any extra play.
