The information (in Test cricket) is hard to come by but I'm pretty
sure that Tudor has set a new record for most runs in a Test innings all
in boundaries. At Birmingham he scored his 32 in the first innings with
eight fours (if cricinfo is to be believed). The previous best was 30
(six fours and one six) by Brian Lara against India at Georgetown in
1996-97. The first-class record is 46 (10 fours and one six) by John
Emburey for England XI against Tasmania at Hobart in 1986-87.
Tudor's 99* contained 21 fours. I don't have any information how it
stacks up against others in Test cricket. In first-class cricket Wasim
Akram (Lancashire v Sussex, Horsham, 1994) scored 98 with 10 fours and
eight sixes (88). RNS Hobbs (Essex v Australians, Chelmsford, 1975)
scored exactly 100 with 12 fours and seven sixes (90). Also, Viv
Richards (West Indians v Glamorgan, Swansea, 1980) scored 100 with nine
fours and nine sixes (90).
