Ekaterina Makarova conceded nerves got to her, as she fell in the semi-finals for a second consecutive grand slam on Thursday.

Makarova was bundled out of the Australian Open 6-3 6-2 by second seed Maria Sharapova on Thursday, the left-hander unable to better her US Open semi-final appearance in September.

It marked Makarova's sixth loss in as many outings against Sharapova, the 10th seed also succumbing to the five-time major winner for a third time in Melbourne alone.

Makarova said the occasion got to her.

"Of course I'm a little bit upset that I lost. But she's a great champion and she been so many times in this situation, in this round," Makarova said.

"She won so many grand slams. I was a little bit too nervous maybe, and I took so much experience from this match."

She added: "I think it's more emotions, more psychology working at this level, these matches. It's definitely not even more tennis, more the head."

Sharapova, into her fourth final at Melbourne Park, said a quick start was crucial to her imposing herself on Makarova once more.

"Today, I thought I played solid. I did everything I had to do," Sharapova, the 2008 champion, said.

"I wasn't afraid for it to become a physical match. I think it was important to really stand my ground in the first few games, which I did well, even though I was behind, especially the first and second one.

"But those key moments are really important. Definitely happy I was able to win really solid today."
