Dutch sprinter Ranomi Kromowidjojo clocked a sizzling 52.75, a world textile best, to win the 100m freestyle at the SwimCup Eindhoven this evening.

The effort makes her the first woman to officially break 53sec in a textile suit. Libby Lenton (AUS, later Trickett), clocked 52.99 in 2007 but she raced in a mixed relay at the USA Vs AUS duel in the pool in a lane next to Michael Phelps (USA) and her effort was never recognised as an official time.

The best textile time ever by a woman had been 53.05, set by Sarah Sjostrom (SWE) at the same pool in The Netherlands last December. Kromowidjojo also raced inside the Dutch national record that had stood to Marleen Veldhuis at 53.17 since 2009.

Sjostrom beat Veldhuis this evening 53.30 to 53.95 but the Swedish visitor had already succumbed to the cracking pace of the winner down the first 50m and neither could catch her on the way home to an historic time. 

Kromowidjojo was out in 25.93 - to 25.49 for Veldhuis - and back in 26.82.

Coach Jacco Verhaeren had expected something special after having targeted the final of the last Olympic selection meet for the Dutch as the moment to find the "perfect race". Kromowidjojo's underwater work into her stroke out of turns was critical to her progress, said Dutch sources. 

The splits comparison shows the significance of a sub 27sec homecoming effort:

• 25.93 26.82 52.75 Kromowidjojo 2012
• 25.54 27.91 53.45 Ottesen (DEN) joint world champion 2011
• 25.49 27.96 53.45 Herasimenia (BLR) joint world champion 2011
• 26.11 27.55 53.66 Kromowidjojo world titles bronze 2011
• 25.46 26.61 52.07 Steffen (GER) world title and WR 2009 in non-textile

Asked about suits, Kromowidjojo, wearing the arena Carbon-Pro, said with a smile: "It was 99% Ranomi and 1% the suit."

Now third fastest ever in a suit of any kind, Kromowidjojo said: "I thought I didn't want a repeat of losing again. It's a great time to have there ... it gives me quite a lot of confidence. I am now favourite [London 2012] again but that makes no difference to me." 

How Olympic season is shaping up:

• 52.75 Kromowidjojo - April
• 53.05 Sjostrom Dec 2011
• 53.57 Fran Halsall (GBR) March 
• 53.71 Tang Yi (CHN) April
• 53.74 Melanie Schlanger (AUS)

All-suits best performances:

• 52.07 Britta Steffen (GER) 2009
• 52.22 Steffen 2009
• 52.56 Steffen 2009
• 52.62 Libby Trickett (AUS) 2009
• 52.75 Kromowidjojo (NED) 2012
• 52.84 Trickett 2009
• 52.85 Steffen 2009
• 52.87 Francesca Halsall (GBR) 2009
• 52.87 Steffen 2009

Trickett, who broke 53sec six more times at a time of non-textile suits now banned, will not race 100m at London 2012, having missed the cut at Australian trials.

In other events in Eindhoven, Sweden's Stefan Nystrand clocked 48.99 to win the men's 100m freestyle ahead of Amsterdam's Sebastiaan Verschuren, on 49.11.

Sharon of Rouwendaal, of the Eindhoven Eiffel squad in which Kromowidjojo trains, clocked 1.01.07, 0.06sec outside definitive London 2012 cut, though she is likely to make the team for London 2012. Just behind get came Kira Toussaint in  1.01.28, good enough for a ticket to the European Championships in Debrecen next month.

In the men's 100m backstroke, Bastian Leijsen, another Eiffel swimmer, got 0.03sec inside the Olympic cut in 53.86 ahead of Nick Driebergen, on 54.20. Lennart Stekelenburg, of Amsterdam, clocked 2:11.70 to win the 200m breaststroke by a wide margin, the time 0.31sec outside a guaranteed ticket to London 2012. The women's 200m breaststroke went to Sweden's Joline Hostman in 2:26.62.
