The Ashes: Usman Khawaja's century leaves England fighting to save Sydney Test

Australia's Usman Khawaja hit another classy century to leave England needing to bat out the final day to save the fourth Ashes Test at the Sydney Cricket Ground (SCG).

With dark storm clouds closing in, England openers Zak Crawley and Haseeb Hameed survived a tricky 11 over and 50-minute period to reach 30-0 at stumps.

Crawley will resume on 22 and Hameed eight when play resumes at 23:00 GMT on Saturday, with 98 overs scheduled on the final day.

Khawaja shared a partnership of 179 with Cameron Green (74) for the fifth wicket as the hosts recovered from 86-4 to keep Australia's hopes of a 5-0 series clean sweep alive.

Earlier in the day, England added 36 runs to their overnight 258-7, with Jonny Bairstow only able to add 10 more runs before feathering Scott Boland behind to fall for 113.

That left a first-innings deficit of 122 and continued a dismal series with the bat, with them still yet to reach 300.

Ollie Pope kept wicket for England - and did an excellent job, taking four catches - with Jos Buttler and Jonny Bairstow both spending the day off the field with hand injuries.

They - along with Ben Stokes, who did field despite ongoing troubles with a left side strain - have had scans and will continue to be assessed before the fifth Test, which starts in Hobart on 14 January.

Masterful Khawaja blunts England

Khawaja's innings was another masterclass and one that England's batters could do far worse than watch and learn from.

The 35-year-old right-hander was hit by a venomous Mark Wood bouncer first ball and he started slowly and did not look fluent in his strokeplay, but importantly he was able to protect his wicket and guide the inexperienced Green, who was ragged for large parts of his innings, through a sticky period.

Australia were always in control of the game, but at 86-4 the door was slightly ajar for England, who had bowled well and were controlling the scoring rate.

The stand between Khawaja and Green firmly closed it again, and double padlocked it for good measure.

Khawaja, who has now scored more runs than any England batter other than Joe Root in the series, reverse swept, pulled and drove through the covers with an elegant grace for a well-deserved 10th Test century.

It marked a dream return to the Test fold for Australia and he was visibly emotional as he composed himself after the celebrations.

Before the Test he spoke about Travis Head - who tested positive for Covid-19 - reclaiming the place for the final Test, but Khawaja must surely now feature in Hobart.

Australian journalist and Test Match Special commentator Geoff Lemon went as far as saying "there will be fights on the streets" if Australia try and drop him.
