'I was struggling': Steve Smith's startling health revelation after ton

Steve Smith has made a stunning revelation about the health scare he experienced the morning before he smashed a second successive century against India.

Once again, the world's best batsman was the star of the show as his second ton in a row helped the Aussies storm to a 51-run win to clinch the three-match ODI series with one game to spare.

However, Smith has made the extraordinary admission that he wasn't even sure he'd be playing the match after waking up to a case of vertigo on Sunday morning.

Smith's spellbinding 62-ball century at the SCG came just hours after the batting superstar reported feeling dizzy and disoriented earlier in the day.

The 31-year-old said he genuinely thought he'd have to miss the match after feeling unwell in the morning.

"I didn't know I was playing," Smith told cricket.com.au.

"I had a really bad dose of vertigo this morning and I was struggling until ... I came down early to have a hit and a bit of a run around.

Smith says the Aussie team doctor performed several exercises to help relieve the dizziness associated with vertigo and the build up of calcium crystals in his ears that exacerbate the problem.

"The doctor, I think he performed six Epley manoeuvres on me this morning and got the crystals out of my ears and I was struggling for a bit.

"Just pleased to be able to get out here and play another good innings and help the team."

Vertigo has troubled Smith in past

Smith is known to have battled vertigo earlier this year on Australia's white-ball tour of England.

The main concern could be whether the symptoms continue, given Australia's hectic schedule over the next four months which includes Test series against India and South Africa.

Regardless, it was his second straight century on Sunday that sent others into a spin ahead of the summer.

Marnus Labuschagne labelled it one of the best one-day centuries he has seen, while teammate Glenn Maxwell labelled his form "scary".

"It's pretty special to watch," Maxwell said.

"It's looking pretty scary at the moment for opposition teams.

"He's placing the ball as well as anyone would in the world and when he puts the foot down, he goes hard.

"He's still hitting the ball into gaps ... he's calculated and just looks like he's got so much time."

The gun batsman landed in Australia earlier this month after a patchy Indian Premier League campaign that was well below his lofty standards.

But Smith, who declared with glee last week he had "found" his hands, clicked into form while training in quarantine and has already reaped great rewards.

Asked about his strike-rate on Sunday night, Smith suggested he tried whacking the ball too hard in the IPL but is now hitting with "a bit more finesse".

The former captain has a knack of lifting for series against India, having scored seven Test tons and five ODI hundreds against them.
