Eugenie Bouchard simply couldn’t overcome a nervous start.

The Canadian tennis star failed to find her groove Tuesday at the Australian Open, dropping her quarter-final match to Russian Maria Sharapova, who advanced with a comfortable 6-3, 6-2 win.

The No. 2 ranked Sharapova will now take on fellow Russian Ekaterina Makarova in one of two semifinals. Makarova, seeded 10th, dominated No. 3 Simona Halep of Romania 6-4, 6-0 early Tuesday.

Bouchard, the seventh seed in Australia, is 0-4 lifetime against Sharapova, including a three-set loss to the Russian at last year’s French Open semifinal.

"She didn't give me many chances, and against the great players you have to take any chances you can get," Bouchard said. If you don't have time, you have to go for riskier shots, and I made a few too many unforced errors because I was under pressure."

Bouchard, of Westmount, Que., looked uneasy from the onset. She was broken in the opening game of the match and proceeded to lose eight of the next 10 points en route to a quick 0-2 deficit.

Bouchard, 20, had a chance to break in the sixth game, but her backhand off Sharapova’s second serve sailed long to negate the opportunity.

Bouchard made 20 unforced errors and was broken twice in the first set.

The second set saw more of the same, with Sharapova breaking Bouchard in the fourth game. Bouchard had another chance in the next game to break back, but Sharapova erased a 0-30 deficit to hold serve.

The Canadian was broken again in the final game.

"I had to produce a really good performance against Genie," Sharapova said. "She's been playing so confidently and aggressively.

"I felt pretty good from the start, didn't feel I had too many letdowns," Sharapova said, adding that her close call in the second round — facing two match points against a qualifier — sharpened her focus for the rest of the tournament.

"When you are down and out in the second match, I don't want to face that call with my father too many times during a tournament,"

Bouchard had a breakthrough season in 2014, making it to the final of Wimbledon and to the semifinals of the Australian Open and French Open.
