Stats: Ashwin surpasses Steyn

The key statistics of the first day's play between India and Australia in Dharamsala.

Ravichandran Ashwin captured Steve Smith's wicket on the first day in Dharamsala.

• Ravichandran Ashwin took his 79th wicket of this season, surpassing Dale Steyn's record for the most wickets in a season: 78 in 2007-08. Ashwin's 79 wickets have come at an average of 25.87 in 13 Tests, while Steyn's 78 scalps took 12 Tests at an average of 16.24.
   
• The Dharamsala Test is Australia’s 50th in India. Hitherto, only England, with 60 Tests, was the only visiting side to have played 50-plus Tests in India.
   
• Ajinkya Rahane became the 33rd captain to have led India in Tests after Virat Kohli was ruled out of the match due to shoulder injury. Kohli has played 54 consecutive Tests since November 2011 (versus West Indies in Mumbai).
   
• Steven Smith's 20th Test century is his seventh against India. He is one of the nine batsmen to hit seven hundreds or more versus India, joining Ricky Ponting, Garry Sobers and Vivian Richards — eight each and Everton Weekes, Clive Lloyd, Jacques Kallis, Michael Clarke and Shivnarine Chanderpaul — seven each.
   
• Smith has taken 54 Tests to hit 20 hundreds. Only two batsmen have achieved the feat quicker in fewer Tests: Don Bradman (35) and Sunil Gavaskar (50). In terms of innings, Smith is the fourth quickest to 20 Test tons. While Smith took 99 innings, Bradman (55), Gavaskar (93) and Hayden (95) needed fewer.
   
• Having scored four hundreds, (including three as captain) in the 2014-15 series versus India, Smith became first captain to post three hundreds in a Test series twice against India. Sir Donald Bradman had posted four centuries while scoring 715 runs (ave 178.75) in the 1947-48 series — the only one to hit four as captain in a Test series against India.
