David Warner said 63 will remain a special score for Australian cricketers as he dedicated his century in the first Test against India to fallen team-mate Phillip Hughes yesterday.
Warner's inspired 145 off 163 balls helped boost the hosts to 354 for six at the end of day one as Australia returned to action following Hughes' funeral.
The explosive left-hander said he found it challenging when he reached 63, Hughes's score when he was fatally struck in the head by a short-pitched ball in Sydney on November 25.
The Adelaide Oval crowd sensed it too and broke out in sustained applause, as they had before the start of play with a symbolic 63 seconds of clapping to honour Hughes.
"It was quite tough when I was on 63 to actually get that momentum and (batting partner) Michael Clarke asked me if I was okay, and I was," Warner said.
"I had to step away for a couple of seconds to get the thought process back again."
Asked if 63 will now hold a special significance in Australia, Warner said: "In this generation I think 100 percent, it's going to be with us for the rest of our careers.
"It's one of those things where you just have to soldier on and do your best. We know he's always going to be with us."
Warner said he was in two minds whether to celebrate with his trademark exuberant jump upon reaching his 10th Test century, and fifth hundred this year.
"It was in the back of my mind whether I should celebrate or not but I know what Hughesy's like and he would always have told me to keep jumping," he said. "I dedicate that hundred to him."
Warner said his pain over Hughes will not subside, and he is expecting it to be worse when the India series moves to the fourth Test at the Sydney Cricket Ground in the New Year.
"For me, personally, I think the hardest thing for me is going to be the New Year's Day Test at the SCG, where it happened," Warner said.
"I think it will be the toughest task for me and the other guys who were there as well."
