Elena Rybakina, world number 13, defeated Emma Raducanu in the opening round of the Sydney Tennis Classic.
Raducanu, the US Open champion, dropped her first match of the year in just 55 minutes to Kazakhstan’s Rybakina.
It was the new head coach Torben Beltz’s first competitive match with the British No 1.
“I got a box of balls and headed directly to the practice court after the game,” Raducanu remarked.
“I thought I could have done some things better, and I wanted to try to remedy it right away so I could leave with a better feeling.”
Raducanu, 19, battled with her serve throughout the first set, committing four double faults.
She came back from a 3-0 deficit in the second game to win her only game of the match.
Raducanu did manage to save two match points before Rybakina sealed the victory and advanced to the last-16, where she will face Caroline Garcia of France.
“I simply wasn’t going to lose love and affection,” she continued, “so that was my purpose.”
“At the end of the day, all I want to do is keep putting myself out there,” she says. It’s just a matter of getting back up and falling in front, even if I keep getting pushed down. You’ve progressed one step further. You gain greater knowledge.”
Raducanu, the British number one, will be seeded 17th for the Australian Open after being the first singles qualifier to win a Grand Slam at the US Open last year.
Her training has been complicated by the fact that she withdrew from the opening WTA tournament of the season in Melbourne last week, having recently emerged from isolation following about with Covid-19.
Raducanu stated she wanted to “test where I’m at” with a competitive match despite not playing for 21 days after a positive Covid-19 test.
“It’s difficult, but it’s nice,” she remarked, “because I’m extremely pleased and happy that I put myself out there.”
“I could have easily stated it was too soon and that I’d play next week, but I wanted to truly put myself in a competitive position. I believe this will assist me in placing myself in a better position for next week.”
