The match was played on indoor courts again, due to constant rain in Auckland, which aided the Belgian, who grew up playing inside and trained under a roof in the off-season.
Not only because of the slicker, faster surface – which suits her flat style – but also because Fernandez is the kind of player that feeds off the energy of the crowd.
The 20-year-old, who has charmed everyone on and off the court during her time here, never stopped fighting – forcing six break opportunities.
But she could only take one, whereas Bonaventure broke Fernandez twice in each set.
Fernandez may have been affected by her schedule.
She had a late match on Thursday night, not leaving the ASB Tennis Centre until close to midnight, then was back on court just after 4pm on Friday.
But it’s a huge result for Bonaventure. She has won 12 ITF titles but had never reached an tour-level semifinal before.
“I came [to Auckland] with no pressure – I knew I could play great tennis and I ended the season with some great wins,” said Bonaventure. “I guess mentally I have been able to stay consistent and really be confident in my game and it showed on the court.”
After more than a decade on tour, the veteran finally cracked the top 100 in October last year.
Bonaventure admitted it had been a lifelong goal, but also created some mental pressure.
“Finally making it after so many years on tour - it has been a relief but it was also very tough to process,” said Bonaventure. “I also knew I had a [ITF] title to defend this week, so if I didn’t do well I would be out of the top 100.”
Her off-season has been far from perfect – “I’ve had some tough days and my team has as well” - and her form in Auckland was a bit of a mystery.
“I can’t explain why I have been playing this good this week,” said Bonaventure.
The Belgian will face Spanish qualifier Rebeka Masarova in Saturday’s semi-final.
Masarova earned her spot after an intense battle with Czech Karolina Muchova, prevailing 7-6(4) 7-6(2) in just over two hours.
It was by far the tighest quarter final, some epic rallies. Muchova had chances in both sets - but couldn’t take them - and the world No 130 was too good in both tiebreaks, limiting errors and serving big.
