In ODIs since 2011 Imran Tahir has been the second-highest impact spinner in the world after Saeed Ajmal. His failure rate of only 19% in 43 ODIs is also the second-best for any bowler in the world in this time frame after Mohammed Shami (16% in 44 ODIs).
AB de Villiers is only the seventh-highest impact batsman for South Africa in T20Is after Faf du Plessis, Jacques Kallis, Graeme Smith, Quinton de Kock, JP Duminy and Hashim Amla. His Batting Impact drops by 39% in T20Is in comparison to domestic T20s.
Since 2014, Suresh Raina's Batting Impact in ODIs has increased by 21%. His failure rate has also improved to 37% (in 30 matches) in this time frame as compared to 50% (in 178 matches) before that. In fact, he is India's second-most consistent batsman in ODIs in this period after MS Dhoni.
Before being caught in the spot-fixing scandal, Mohammad Asif had produced three series-defining performances (SD) in only 23 Test matches. His ratio of one SD in approximately every eight Tests is the best for any pacer in the history of Test cricket.
Since his debut for West Indies in Tests, Jason Holder has been the most consistent West Indian player and has failed in only one of his seven Tests (only matches with two completed innings included). Interestingly, his Batting Impact is higher than his Bowling Impact in this format of the game.
Ashish Nehra has had a 46% higher impact than Sreenath Aravind in the last two years in T20 cricket and is the highest impact Indian bowler in this format in the mentioned time frame.
There have been a total of 70 series-defining performances (SDs) in the last two years in ODIs. The country-wise breakdown is such: AUS (17), SL (13), SA (10), ENG (8), NZ (7), IND (6), BAN (5), WI (3) & PAK (1). AUS have had 12 different players producing SDs, they are followed on this count by SL (11) and ENG (7).
England's highest impact bowler in Tests on their previous tour to the UAE was Monty Panesar. He followed it up with a series-defining performance against India- undoubtedly the highest point of his career. England embark on another tour to the UAE, but this time around Monty finds himself ousted even from his county (Essex).
Mitchell Marsh produced the second series-defining performance of his career in only his 21st ODI in the recently concluded series against England. His father, Geoff Marsh, produced 3 SDs in his 115-match ODI career while his brother Shaun Marsh has none in 45 ODIs. Clearly, Mitchell is on his way to family royalty.
Four out of the seven highest impact batting performances of Brad Haddin's Test career came in the Ashes 2013/14 series.
It has always been an intriguing question. Who is better between left-handers and right-handers? We, at Impact Index try and do an analysis to find out who - left-handed batsmen or right-handed batsmen, had a higher impact with the bat.
Darren Gough gave 3 series-defining performances in his career - the most by any fast bowler from England. He was the second-highest impact pace bowler after Allan Donald during his career (1994-2003).
