Heather Watson's run at the Nuremberg Cup came to an end with a straight-sets defeat in round two to a qualifier ranked 117 places below her.
The Briton lost 6-3 6-3 to world number 203 Fanny Stollar from Hungary.
Watson lost her opening service game but although she broke back, she was broken again as Stoller, 19, made it 5-3 and then took the opening set.
Watson then dropped her serve twice in the second set to trail 4-1 and was unable to break back.
Draw for the French Open at Roland Garros:
Johanna Konta (34) faces Kazakhstan's Yulia Putintseva (109)
Heather Watson (146) will face France's Oceane Dodin (242)
Rankings in brackets are the Porsche Race figures in order to give a more realistic postion of the drop in form of the British players. Heather Watson is now 5th in the British rankings.
British number one Johanna Konta's struggles at Roland Garros continued as she lost in the French Open first round for the fourth successive year.
The 22nd seed lost 6-4 6-3 to Kazakhstan's Yulia Putintseva.
Konta spoke positively in the build-up about her ability on the red clay, but made too many unforced errors against an opponent ranked 93rd in the world.
Heather Watson, Britain's only other player in the women's draw, faces France's Oceane Dodin on Monday.
Konta's stock rose, along with her ranking, on the back of a wonderful grass-court season last year, in which she reached the Wimbledon semi-finals.
But she has struggled to match those heights since, reaching just one quarter-final this year, in Brisbane in January.
Although clay is the former world number four's least favourite surface, she talked up her ability on the dirt before Sunday's opening match and pointed to her record in French Open qualifying as an indication she can perform at Roland Garros.
This defeat, however, was less to do with the surface and more to do with her aggressive, and sometimes wild, shot-making.
Konta made 32 unforced errors, compared with just 22 winners, with another loose backhand up the line somewhat fittingly ending the match, in an hour and 24 minutes.
Heather Watson reached the French Open second round for the sixth time after breezing to a confidence-boosting win over home hope Oceane Dodin.
The British number two had only won once this year before Roland Garros, but impressed in a 6-3 6-0 victory.
Watson, 26, dominated the match as Dodin wilted, although she stuttered slightly in a marathon final game before taking her fifth match point.
She will face 16th seed Elise Mertens or American Varvara Lepchenko next. That match was suspended last night wuth one set each and Mertens ahead in the final set 0-3.
"I came out a bit nervy and once I got that out of me I was on fire and played really well," Watson told BBC Sport. "That's the best I've served in a match for a long time.
"Serving out was tough because it was raining and you could feel it getting harder. You want to get it done but also not rush.
"When you're trying to serve and you've got rain going into your eyes it is tough, plus she stepped up her game."
In the build-up to the second Grand Slam of the year, Watson had said that she had not paid attention to her run eight successive defeats, saying she was only hearing of it through social media.
That sequence ended with a victory in Nuremberg last week, with Watson adding before her opener against Dodin that she felt she was "not playing badly but things are not clicking".
With a vociferous British backing behind her, despite playing against a home player, Watson's words rang true as she produced her finest performance of the year.
Watson, now ranked 80th in the world, lost her opening serve to trail 2-0 but fought back strongly to take the first set in 34 minutes.
She sensed Dodin's vulnerability as the French world number 139 refused to change her wild-hitting approach, taking the momentum into a second set where she swept her opponent off court.
The only minor blip in an excellent performance came in what proved to the final game, when she failed to convert four match points - and staved off four break points - in an agonisingly long deuce.
With rain starting to fall in Paris, Watson saw the job through, winning 84% of her first-serve points and hitting nine aces in the match.
She says the victory over Ukraine's Kateryna Bondarenko in Nuremberg lifted the pressure of her losing streak and allowed to play more confidently against Dodin.
"I was so pleased to get through that match against Bondarenko because there had been this losing run, which I hadn't even thought of until everyone started writing about it, then that started to play on my mind," she said.
"It was different today - I felt very confident."
British number two Heather Watson was unable to reach the French Open third round for the first time after losing to 16th seed Elise Mertens.
Watson, 26, paid the price for a slow start in a 6-3 6-4 defeat.
The world number 80 could not hold any of her opening seven service games and trailed 4-1 in the second set.
She briefly rallied to level at 4-4 but dropped serve again and has now lost all six of her second-round matches at Roland Garros.
BBC reports that top seed Heather Watson was knocked out of the Surbiton Trophy grass-court tournament by fellow Briton Gabriella Taylor, ranked 104 places below her, losing 3-6 6-4 6-3.
Those ranking numbers the BBC used were the ordinary WTA ones. If they had used the Porsche race numbers (based just on current year rather than last 12 months) they would have seen that Gabriella Taylor is GB's number 2 at 102 and Heather Watson number 4 at 126.
Gabriella Taylor is 20 so is one to look out for in the future.
British number one Johanna Konta began her grass-court singles campaign with a straight-set win over Japan's Kurumi Nara at the Nottingham Open.
Konta, the world number 22, won 6-2 6-3 to reach the second round.
British number two Heather Watson also moved into the second round with a 6-1 6-3 win against American Danielle Lao.
One of them will get through to the third round as they meet in the second round.
Johanna Konta beat Heather Watson in a close match 6-4, 7-6.
In the same tournament, British number four Katie Boulter beat 2011 US Open champion Sam Stosur to reach her first WTA Tour quarter-final.
The 21-year-old, ranked 53 places below the Australian, powered to a 7-6 (8-6) 6-1 victory in Nottingham.
It is the latest in a series of promising results for Boulter, who won ITF tournaments in Japan and Portugal earlier this year.
She will face top seed Ashleigh Barty or Duan Ying-ying in the last eight.
British number one Johanna Konta beat Dalila Jakupovic at the Nature Valley Open to reach her first semi-final since last year's Wimbledon.
Fourth seed Konta beat the 118th-ranked Slovenian 6-4-6-2 to set up a semi-final meeting with Donna Vekic.
Vekic beat Konta in last year's final in Nottingham, but Konta overcame the Croat during her run at Wimbledon.
Fellow Briton Katie Boulter, however, fell to a straight-set quarter-final defeat by top seed Ashleigh Barty.
Australian Barty needed just 59 minutes to wrap up a 6-0 6-2 victory over the British number four.
From yesterday.
British number one Johanna Konta reached the final of the Nature Valley Open in Nottingham for the second year in a row after a straight-set win over Donna Vekic.
Konta beat the defending champion from Croatia 6-2 6-3 in a match delayed for over an hour because of rain.
She will face top seed Ashleigh Barty from Australia in Sunday's final.
Barty defeated Japanese third seed Naomi Osaka 6-3 6-4 in the opening semi-final.
From yesterday.
A furious Johanna Konta lost out to Ashleigh Barty in the final of the Nature Valley Open in Nottingham.
Konta had recovered from 4-1 down in the decider to level at 4-4 but a controversial call allowed Barty go 5-4 ahead.
The Briton got into a heated discussion with umpire Paula Vieira Souza, which seemed to affect her concentration.
She was broken in the next game to give Barty a 6-3 3-6 6-4 win and did not shake the umpire's hand at the end.
"At 4-4 in the third set, that's quite an important time of any match," Konta said. "It's a difficult position to be in.
"I definitely burned through quite a bit of energy at that moment in time.
"But, except for one loose shot [in the last game], I don't think I did too much wrong.
"Obviously I'm a little bit sad I could not come through with the win today but I'm also taking a lot of positives from this week in general."
British number one Johanna Konta lost 6-3 6-4 to defending champion Petra Kvitova in the first round of the Nature Valley Classic in Birmingham.
Konta, who had an argument with the umpire in losing Sunday's Nottingham Open final, served seven double faults.
British number two Heather Watson also lost, beaten 7-6 (7-2) 7-5 by Ukraine's Lesia Tsurenko.
Although Johanna Konta won her first match at Eastbourne easily 6-1, 6-3, Caroline Wozniacki beat her in the second winning 4-6, 6-1, 6-4.
Anastasija Sevastova beat Harriet Dart 6-3, 6-4.
Next is Wimbledon. Johanna Konta is seeded 22. Draw is made tomorrow. It could well be one of those years where there are no British players left in the tournament after the first two rounds in the womens singles.
Wimbledon first round drawn for the Ladies' Singles re the British players:
Johanna Konta v Natalia Vikhlyantseva (on paper Johanna would be expected to win)
Jelena Ostapenko v Katy Dunne
Heather Watson v Kirsten Flipkens
Garbine Muguruza v Naomi Broady (nearly the toughest match for any of the British players)
Gabriella Taylor v Eugenie Bouchard (in rankings the closest match)
Katie Boulter v Veronica Cepede Royg (Katie not that far ranked below her opponent)
Karolina Pliskova v Harriet Dart (the toughest match for any of the Britiish players)
Irina-Camelia Begu v Katie Swan (the third toughest match)
So Johanna Konta is the most likely to get to the second round, Gabriella Taylor and Katie Boulter could also get through, but don't expect any of the others to.
In the Ladies doubles Heather Watson and Tatjana Maria could make progress as could Anna Smith and Xenia Knoll.
The mixed doubles draw won't be made for some days so too soon to know if Heather Watson and Henri Kontinen (champions in 2016) will be in it.
British wildcard Harriet Dart gave seventh seed Karolina Pliskova of the Czech Republic a scare but her Wimbledon debut ended in defeat.
Former world number one Pliskova won 7-6 (7-2) 2-6 6-1 in their first-round match as Dart played impressively in her first meeting with a top-10 player.
Dart, 21, played with confidence against her 26-year-old opponent as she fought back to level at one set all.
By the third set, Pliskova discovered her rhythm to secure safe passage.
Not to be, Gabriella Taylor lost to Eugenie Bouchard 0-6, 6-4, 3-6.
Katie Boulter's match starts soon, Katy Dunn's match hasn't yet been given a court and Heather Watson's match is scheduled to take place after a men's singles match which has only just started to could be the last British match today.
The expected results yesterday for the other two British players both losing:
Jelena Ostapenko beat Katy Dunne 6-3, 7-6 (7-5) and
Heather Watson lost to Kirsten Flipkens 4-6, 5-7.
The results mean that Heather Watson is no longer the British number 2 who is now Katie Boulter (unless Katie Swan makes very good progress through the tournament, better than Katie Boulter).
It is Katie Swan's second round match today against the number 29 seed Mihaela BuzÄrnescu.
First match of the last two in Wimbledon is Katie Boulter against the 18th seed Naomi Osaka so a tough match.
Second match late afternoon is Johanna Konta against Dominika Cibulkova who would have been seeded if not for Serena Williams being seeded instead. Johanna Konta needs to win to avoid dropping in the rankings to around 45/50.
Regardless of today's results Katie Boulter will become British number 2 and if she got to the 4th round would break into the top 100 (quite likely to be just a question of when rather than if).
Heather Watson and Henri Kontinen are in the mixed doubles draw seeded 16 and get a bye in the first round. Although other Brits are in the draw, Heather Watson is the only seeded one. Although not doing well in singles, when it comes to doubles she and Anna Smith are close to being the top Brit.

Headline news has to be Serena Williams being detroyed by Johnna Konta 1-6, 0-6in the Silicon Valley Classic (which is the new name for Bank of West Stanford Classic - BBC still using either name just to cause confusion). Heather Watson also won in the same tournament beating Claire Liu 6-4,3-6,6-4.
In the Citi Open at Washington Katie Boulter also won beating Aleksandra Krunic 6-2, 6-0.
She's 19 so right at the start of her adult playing career.
