How many men have scored a Test triple-century in a team's second innings?

Who was Yabba, apparently the only spectator at the recent ODI between Australia and New Zealand? asked Maurice Evans from New Zealand
"Yabba" was the nickname given to Stephen Harold Gascoigne, a Sydney rabbit-seller who became famous for his raucous pronouncements from the Hill during matches at the SCG. Arguably the best-recalled example of his output was his advice to the England captain Douglas Jardine during the Bodyline tour: "Leave our flies alone Jardine! They're the only friends you've got out here."

A statue of Yabba was unveiled on the Hill in 2008, which is why he was, poetically speaking, the only onlooker at the recent ODI in Sydney, after spectators were excluded for health reasons. The official attendance of zero would appear to be an unbeatable record low: according to the Melbourne statistician Charles Davis, the previous-smallest daily attendance for an international match in Australia was 17, for the final day of the 1967-68 Adelaide Test - India were nine down overnight, and 161 behind; Australia needed six overs on the final morning to pick up the last wicket.

Ian Chappell, in a recent ESPNcricinfo article, entertainingly recalled a Sheffield Shield match that started with just one spectator in attendance. I seem to remember a report of a match in Zimbabwe that started with no one watching at all, but I'm not sure when that was!

I noticed that Mitchell Starc has bowled 70 of his 178 victims in ODIs, which is almost 40%. Is this a record? asked Rick McDonough from Australia
Mitchell Starc's percentage of bowled dismissals in one-day internationals - 39.33% - is indeed a record for anyone with more than 100 wickets. Next come Waqar Younis, with 151 out of 416 (36.3%), the West Indian Jerome Taylor, with 45 out of 128 (35.16%) and Wasim Akram, with 176 out of 502 (35.06%). If we drop the qualification to 50 wickets, Starc comes in third, behind another Pakistani - offspinner Tauseef Ahmed, with 23 bowled out of 55 wickets (41.82%) - and another rapid Aussie, Shaun Tait, with 25 out of 62 (40.32%).

How many men have scored a Test triple-century in a team's second innings? asked Ahmed Raza from Pakistan
Only two batsmen have managed a triple-century in their team's second innings in a Test. For a long time the only one to achieve it was Hanif Mohammad, with his monumental match-saving 337 against West Indies in Bridgetown in 1957-58. With Pakistan trailing by 473 runs after the first innings, Hanif batted for 970 minutes (or 999, by some accounts), and Pakistan escaped with a draw. Nearly 56 years later, in February 2014, Hanif was joined by Brendon McCullum, who made 302 (in 775 minutes) for New Zealand against India in Wellington.

The highest score in the fourth innings of a Test is 223, by George Headley for West Indies against England in a timeless Test in Kingston in 1929-30. For the full list of second-innings double-centuries, click here.

I noticed that Kane Williamson had made seven nineties in ODIs, and Virat Kohli six. Who's top of this list? asked Anuram Bhatti from India
Kane Williamson's current tally of seven scores of between 90 and 99 in one-day internationals puts him joint-sixth (with India's Mohammad Azharuddin) on this particular list. Jacques Kallis made eight, and Nathan Astle, Aravinda de Silva and Grant Flower nine - but way ahead, with twice as many, is Sachin Tendulkar, whose 18 included three 99s.

What's the most wickets in a Test by someone who also bagged a pair? asked Ron Houghton from England
The Surrey and England bowler George Lohmann holds this particular record. He took 15 wickets - 7 for 38 and 8 for 7 - against South Africa in Port Elizabeth in 1895-96, but was also dismissed for ducks in both innings.

More recently, Bhagwath Chandrasekhar took 12 for 104 (two 6 for 52s) for India against Australia in Melbourne in 1977-78, and Waqar Younis 12 for 130 (7 for 76 and 5 for 54) for Pakistan against New Zealand in Faisalabad in 1990-91. In all, there have been 11 instances of a bowler combining ten or more wickets in a Test with a pair with the bat.
