In the first ever Test, in 1877, Charles Bannerman scored an unbeaten 165 out of Australia's 245, which is a 67.34% contribution. Since then, the closest anyone has come to that mark is Michael Slater, who scored 66.84% of his team's runs (123 out of 184) in the New Year Test at the SCG in 1999.
One of the England players in that 1877 match above, England's James Southerton, was 49 years and 119 days old when the Test began. He remains the oldest debutant in Test cricket. Among the 15 oldest debutants on this list, only one started his Test career after 1960: South Africa's Omar Henry, who debuted in 1992.
Among the many records by Don Bradman that haven't been broken yet is the one for highest aggregate in a Test series. He accumulated 974 runs in the 1930 Ashes, in which he scored four centuries. Three of those were double-centuries, which is also a record for any series. The closest any batsman has come to this in the last 50 years was when Mark Taylor made 839 runs in the 1989 Ashes. Steven Smith aggregated 750-plus runs in a series twice in the last decade.
Jim Laker's 10 for 53 in an innings and 19 for 90 in the match, at Old Trafford against Australia in 1956, are still the best innings and match figures in Tests. Anil Kumble is the only other bowler to take ten in an innings (10 for 74), but no bowler has matched Laker's 19 wickets in a match even in first-class cricket.
Wilfred Rhodes played 58 Tests in a 30-year-long career between 1899 and 1930. He was 53 when he played his final Test. In recent times, Sachin Tendulkar came closest to that mark when he retired in 2013 after a career of 24 years.
Both these records are over 100 years old: Albert Trott picked up 8 for 43 on his debut in 1895, figures that haven't been bettered by a debutant, though Bob Massie (in 1972) and Narendra Hirwani (1988) took eight wickets in each innings on their debut.
Sydney Barnes picked up 49 wickets in a four-match series against South Africa in 1913-14, which remains a record for the most wickets in a series. In the last 30 years, only once has a bowler touched the 40-wicket mark in a series - Shane Warne in the 2005 Ashes.
Clyde Walcott scored five centuries in the five-match series against Australia in 1955. Several players have scored four hundreds in a series, including Virat Kohli and Steven Smith in recent years. Walcott also scored centuries in both innings of a match twice in that series, which is also unmatched by any player yet.
Everton Weekes scored five hundreds in five consecutive innings in 1948, a record that is yet to be matched in more than 70 years since. Rahul Dravid came closest, with four hundreds in four innings in 2002.
Charlie Turner picked up five-wicket hauls in six consecutive innings in 1888, which too has been unequalled since then. In the last 50 years only one bowler has come close - Shane Shillingford took five consecutive five-fors in 2013.
A few months ago, Pakistan's 16-year old sensation Naseem Shah picked up a five-wicket haul against Sri Lanka. However, he missed being the youngest bowler to take a five-for by a few days; that record still belongs to his countryman Nasim-ul-Ghani, from 1958.
Garry Sobers converted his maiden century into a triple and finished on a record unbeaten 365 against Pakistan in 1958. Since then two batsmen have converted their maiden hundreds into triples, including Karun Nair in 2016, but Sobers' innings remains the biggest maiden Test hundred. Sobers also became the youngest to score a triple-century and holds that record still.
Jimmy Matthews of Australia took two hat-tricks in the same Test against South Africa at Old Trafford in 1912. No other bowler has achieved it since. Matthews picked up both those hat-tricks on the same day in different innings of the match.
