NAGPUR: India beat South Africa in a Test series for the first time in 11 years after winning the third Test by 124 runs thanks to Ravichandran Ashwin's 12-wicket match haul on Friday.

India took a winning 2-0 lead in the four-match series by bowling out South Africa for 185 in the last session of the third day.

Ashwin with his off-spin took 7-66 in the second innings, and 12-98 in the match, to once again lead the charge against a batting lineup that folded for a meagre 79 runs in the first innings.

India scored 215 and 173 to set South Africa 310-run target and three days to win, but the Proteas lost a series away from home for the first time in nine years.

Tormented on spin-friendly tracks, South Africa lost this Test much like it did in the first one in Mohali, where it was beaten by 108 runs, also in under three days.

The second Test at Bangalore was a washed-out draw.

The fourth Ten-for in 31 Tests for Ashwin was supported by leg-spinner Amit Mishra, who accounted for South Africa high-scorers captain Hashim Amla and Faf du Plessis, who made 39 runs apiece.

Their defiant 72-run, fifth-wicket partnership lasted 46.2 overs until Amla was caught by captain Virat Kohli at gully off Mishra. Mishra then bowled du Plessis, who went for a pull shot but the ball kept low.

“While (Ashwin and Ravindra Jadeja) are very consistent, Mishra is very economical for a leg-spinner, which is not a regular sight,” Kohli said.

The Amla-du Plessis stand was the second highest for South Africa in this series, after the 76-run partnership between Amla and Dean Elgar for the third wicket in the first innings at Mohali.

The pitch seemed to play a little slower than on the first two days, and Amla and du Plessis negotiated the bowling with some difficulty, as the ball found the edge of the bat a few times but did not carry to the fielders.

The pair looked more confident in the second session, but the runs did not come easy as they scored only 21 off 19 overs in the first hour after lunch.

“It definitely got more difficult to bat,” Amla said.

“From day one to day three, it got progressively worse. That's just what it was.”

It was only a matter of time once Amla and du Plessis departed, and Ashwin was back to finding the right spots on the pitch.

The lower-order batsmen tottered amid mounting pressure, and India claimed only a third series win over South Africa in 12 overall.

Kohli defended the under-prepared pitches during the Test series.

“In the last few years, if you see the statistics of any team, they dominate at home. That is how Test cricket has gone. Whoever has won away from home is the No. 1 or No. 2 side in the world,” Kohli said.

Earlier, resuming on 32-2, South Africa lost two early wickets before Amla and du Plessis forged their partnership.

Ashwin trapped both Elgar (18) and AB de Villiers (9) lbw to bring early cheer to the Indian camp.

The last Test will be in New Delhi from Dec. 3-7.
