Who has bowled the most miserly spell in T20Is?
And was USA's defeat of Pakistan the biggest World Cup upset?

There aren't official rankings for this sort of thing, so this will be a personal view, but the USA's win over Pakistan after a Super Over in Dallas last week must be near the top of the list. In terms of the T20 World Cup, it was the 14th win by a non-Test-playing country over a Test nation (the 15th soon followed, when Canada beat Ireland in New York.) That number includes two wins apiece by Afghanistan and Ireland before they had Test status.
Offspinner Frank Nsubuga had the outstanding figures of 4-2-4-2 in Uganda's T20 World Cup win over Papua New Guinea in Providence (Guyana) last week. This wasn't quite the most miserly four-over spell in all T20Is: for Canada against Panama in Coolidge (Antigua) in November 2021, slow left-armer Saad Bin Zafar delivered four maidens, finishing with 4-4-0-2.
Only two batters have had the mortification of being dismissed for 299 in first-class matches. The first was New Zealand's Martin Crowe, in a Test against Sri Lanka in Wellington in 1990-91. Distracted by the upcoming milestone, he pushed at a gentle medium-pace devliery from his opposite number as captain, Arjuna Ranatunga, and was caught behind. "I had choked," wrote Crowe. "I didn't concentrate. I forgot to say 'Keep still, watch the ball'. Out for 299 - tell me it's not true! Tears streamed down my face as I realised that this opportunity might never happen again." It didn't, for Crowe anyway: and it was another 23 years before Brendon McCullum finally completed New Zealand's first Test triple-century, against India in February 2014, also at the Basin Reserve.
I did remember to check this in connection with last week's answer. No woman has ever scored two centuries in the same Test: the closest was by India's Sandhya Agarwal, who made 143 and 83 against Australia in Mumbai in 1983-84.
There have only been 84 instances of a bowler taking all ten wickets in an innings in 11-a-side first-class matches. But it's correct that two of these happened on the same day - Monday, June 20, 1921. At Cardiff Arms Park, Glamorgan (in their first season in the County Championship) were starting the second innings of their match against Derbyshire, in which 20 wickets had fallen on the first day. The procession continued: Glamorgan were all out for 106, with seamer Billy Bestwick taking all ten wickets for 40. Bestwick was 46 at the time, and remains the oldest bowler to have performed this feat in first-class cricket. He was well known for enjoying a pint or two of beer, as the Derbyshire historian John Shawcroft recalled: "It was a remarkable performance, and it indicates just why the county adopted a tacit policy of turning a blind eye to some of his drinking adventures. Derbyshire accepted Bestwick for what he was - a magnificent bowler whose behaviour, because of his drinking, was sometimes erratic, but who gave of his best on the field."
