Usman Khawaja says he could not stop smiling after hitting another classy century to put Australia in a strong position in the fourth Ashes Test.
Australia are priced at 5/2 to win the Ashes series 5-0 and are now just one day away from making it 4-0 if they can skittle through the England batting order on Sunday.
Australia got day four off to a great start when dismissing England, who managed to add just 36 more runs to their overnight total with Jonny Bairstow out for 113.
Australia led by 122 runs but England fought back to have the baggy greens at 4-86 in their second innings before Khawaja came to the rescue once again when putting on a partnership of 179 with Cameron Green.
Khawaja was unbeaten on 101 when Australia declared, while Green contributed 74 runs, his best innings of the series so far to answer the doubters.
"I couldn't stop smiling. I was grateful with one hundred, but I'll take the second one too," Khawaja said after the end of the day's play.
"I enjoy the SCG. It's my home away from home. I love it here. I was just trying to bat and build a partnership, trying to take time out of the game and build the lead."
England were set an unlikely target of 388 to win the Test and avoided losing any wickets before the close, finishing 0-30.
England need to bat the day out and the weather forecast is mixed but Khawaja is confident the bowlers can take 10 wickets.
"It reminds me of an old-school SCG wicket. Hopefully it will be a dry day and we can get some reverse swing. Nathan Lyon will hopefully come into the game," he added.
