There have been only 9 instances when a player has scored more than 300 runs and has notched up 20 plus wickets in a series since 1960 and 15 times in the history of Test cricket. But there is a good chance that this record might just increase by a number and another Indian after Kapil Dev will make it to the list. 

With 209 runs and 11 wickets already in his kitty and 3 more test matches to be played one can easily expect Bhuvneshwar Kumar to enter the this list and quiet possibly top it as well. 

First let us take a look at players to score 300+ runs and take 20+ wickets in a series since 1960 –

Player Series Matches Runs Wickets
Garry Sobers India in WI. 1961-62 5 424 23
Garry Sobers WI in England, 1963 5 322 20
Garry Sobers WI in England, 1966 5 722 20
Tony Greig England in WI, 1973-74 5 430 24
Ian Botham The Ashes in England, 1981 6 399 34
Kapil Dev England in India, 1981-82 6 318 22
Richard Hadlee NZ in England, 1983 4 301 21
Shaun Pollock SA in West Indies, 2000-01 5 302 20
Andrew Flintoff The Ashes in England, 2005 5 402 24

Probably next on list:

Bhuvneswar Kumar India in England, 2014                     2                 209        11           

Andrew Flintoff was the last player to score 300 or more runs and pick up 20 or more wickets in Test cricket in a single series. Almost 9 years have passed by and now here is young Indian bowlers who has the best chance to get his name listed along with legendary cricketers that too in a series that is being played at England.
