Spare a thought for Grigor Dimitrov.
With Roger Federer already through to the Australian Open final, all eyes are on whether long time rival Rafael Nadal will also advance and set up another classic match-up.
To do that Nadal, who is aiming to make his 21st grand slam final, would have to beat the Bulgarian who is attempting to make his first ever grand slam final.
Nadal is very aware a ninth grand slam final match up against Federer is not a done deal.
Even with such vast experience on the big occasion of a grand slam, Nadal is nervous.
His jitters aren't eased by an impressive 7-1 head-to-head lead over Australian Open semifinal rival Dimitrov.
For a start, the 14-time major winner is aware Dimitrov broke through against him last time, in Beijing less than four months ago. And the emerging Bulgarian picked up where he left off late last year by winning the singles title in Brisbane three weeks ago in the perfect lead-up to the season's first major championship.
"He's a player that has an unbelievable talent, unbelievable potential," Nadal said. "He started the season playing unbelievable.
"It's going to be a very tough match for me. I hope for him, too. I'm going to try to play my best because I know he's playing with high confidence."
Nadal certainty won't shy from another challenge and he draws strength from his own form that accounted for German teenager Alexander Zverev, Frenchman Gael Monfils and then big-serving Canadian Milos Raonic.
"I think all of them are top players. So that's very important for me because that means that I'm competitive and playing well," said Nadal, who won the Australian title in 2009. "Very happy that after a lot of work, to be in this round again. Is a special thing for me, especially here in Australia."
Nadal reversed the recent loss to Raonic in Brisbane, where he was returning from a couple of months off to rest his injured left wrist. He went in with a more aggressive approach in Melbourne, taking the ball earlier to force errors as he surged to his 50th Grand Slam win at Melbourne Park and into his 24th major semifinal.
"Even moments he played so good from the baseline, I was there trying to stop his aggressive shots and don't lose court, don't lose meters behind the baseline. That's an important change for me," Nadal said. "I feel very happy for my attitude. I hit some great passing shots. That's good news for me. When I make that happen, it's because I'm playing well."
No. 15-seeded Dimitrov conceded only nine games to 11th-seeded Belgian David Goffin in a clinical warm-up for his semifinal with Nadal and a possible shot at Sunday's final against Roger Federer.
He's fit and fresh after rebuilding a ranking that slipped to 40 last July, his lowest standing for more than three years.
"I just kept doing the things that I was believing in," he said, paying tribute to his coach Daniel Vallverdu and fitness trainer and others who "were there for me at the tough time."
"I never felt that I was doing something wrong. I just felt that I was not playing and practicing well, not doing the right things. But with the right set of people, things started to slowly move forward for me. Now I think I'm just in a good place."
Dimitrov said he had the talent and the preparation to reach his first Grand Slam final.
"I feel like I have all the tools to go further and my job isn't over yet." He said. "I'm ready to go the distance.
"Just going forward with the confidence that I have built up also from the previous tournament. With each match I've been feeling better and better - It just all comes pretty natural right now."
Dimitrov had the luxury of watching the Nadal-Raonic duel Wednesday night while relaxing in his hotel room, staying in for the night to focus on his Open advance.
"Right now I'm enjoying the fight, that's for sure. I'm enjoying running down every ball. When you feel physically good and you feel to kind of get into a match, that gives you a different perspective as soon as you get out on the court," he said. "Whoever you play, you know you're going to get your chance."
