 On the fourth day Ian Redpath was bowled again by Willis to leave Australia 59/3, but after this Greg Chappell (71), Ross Edwards (53), Doug Walters (63 not out) and Rod Marsh (46 not out) set about extending the lead.Chappell and Edwards added 114, without getting away from the tight bowling and defensive fields and Knott took his 174th Test catch off Willis to dismiss Edwards, thus breaking Godfrey Evans's 15-year-old record.It took some robust strokeplay from Walters and Marsh to bring the score to 288/5 in under 8 hours, Marsh hitting Underwood for a four and a six off successive balls before being dropped by the substitute Chris Old in the outfield and Walters hitting the 100,000th run for Australia against England on 199/5.
