WATCH | Ashwin becomes second Indian to take 500 Test wickets; Other stats you need to know about the spinner-

R Ashwin became the ninth man, and the second Indian to take 500 Test wickets on the second day in Rajkot, dismissing England's Zak Crawley. He is also the second-fastest to achieve the feat, getting there in his 98th Test.
Ashwin's 500th wicket came at a very crucial time as England's openers had responded to India's first-innings score of 445 with an 89-run stand in just 13 overs. He broke the partnership by dismissing Crawley.

Ashwin, who made his Test debut in November 2011, has been India’s strike bowler in Tests, particularly at home, where 347 of his 500 wickets have come. 
Only Anil Kumble, who has 619 wickets, is ahead of Ashwin among Indians on the wicket-takers' tally in Tests. He is also only the third offspinner to the mark, alongside Muthiah Muralidaran and Nathan Lyon.
