Samoa condemned Wales to their fifth straight defeat of the year after taking the spoils 26-19 at the Millennium Stadium in Cardiff on Friday.
Samoa sent Six Nations holders Wales crashing to their fifth consecutive loss after the visitors secured a 26-19 win at the Millennium Stadium on Friday.
It was the hosts' fourth negative to the islanders and followed Rob Howley's charges' defeat to Argentina at the same venue only one week ago.
Suddenly a November whitewash seems likely, with Wales now preparing to face New Zealand and Australia in their final Test series fixtures.
The visitors came out of the blocks firing as they looked to kick on from their impressive win over Canada in Colwyn Bay a week ago. And they managed to cross the whitewash within two minutes against the sterner opposition when number eight Taiasina Tuifua broke through a somewhat non-existent defence before recycled ball was moved wide to Paul Williams and then George Pisi, with the Northampton Saints centre sending over Faatoina Autagavaia on the right.
The impressive Tusi Pisi's conversion made it 0-7 with the match still very much in its infancy. For Welsh supporters, it was a moment of realisation, realisation that their Grand Slam champions were in for a big test of their credentials.
Leigh Halfpenny, who was on-form with the boot in Cardiff, pulled the hosts back to 3-7 with 16 minutes played after a ruck infringement and then cut matters down to a point on the half-hour. By this point Wales had been forced to make a change, as Richard Hibbard was hurt.
Despite their six points, Wales were not having things their own way but were the recipients of a gift from Pisi, with the fly-half throwing a suicide pass that Ashley Beck gobbled up and then set off for a 70 metre sprint to the whitewash. Halfpenny made it 13-7 with the extras.
The assured Pisi did reduce the arrears off the kicking tee with the last play of the first-half, which made the contest beautifully balanced at 13-10 with 40 minutes remaining in Cardiff.
After the turnaround the match continued to excite and when Kahn Fotuali'i scooted down the blindside at a ruck close to halfway to set up centre Pisi for a superb finish in the corner, the Samoans were ahead again. Fly-half Tusi could not add the extras however, and one wondered whether that missed conversion on 47 minutes would come back to hurt them.
An exchange of penalties from Halfpenny and Pisi then troubled the scorers as the lead changed hands five times during the second-half. Up 21-19, Samoa repelled a rare attack by Wales soon after, with the hosts struggling to make any real headway with ball in hand.
Instead it was Samoa who had the final say when David Lemi kicked ahead, Halfpenny and Autagavaia both missed the bouncing ball to hand replacement Johnny Leota a try late on.
Man of the match: A toss-up between the half-backs in blue. Let's go for Tusi Pisi's effort.
Moment of the match: The finish from George Pisi was something special. It had to be him.
Villain of the match: Maybe of a couple of let's say 'choice' tackles could make it in there but there was nothing major to write home about. Next up for the Welsh will be New Zealand.

In spells it was a performance that showed once again why the All Blacks are considered the finest exponents of attacking rugby in the game. It also backed up the importance of all players - from 1 to 15 - being comfortable in any position as forward duo Luke Romano and Wyatt Crockett proved.
Both sides conceded penalty tries in a three-minute span, Romania deliberately collapsing a maul, and Japan collapsing a scrum, to leave Japan leading by one with eight minutes to go.
The result brings an end to Australia's five-game winning streak against les Bleus and puts France in pole position in the chase for the all-important fourth place in the world rankings ahead of the World Cup pool draw next month.
In a tale of two halves, Ireland looked on course for a famous win after leading their visitors 12-3 at half-time.
Following an early blip whereby the islanders held the upper hand, England clicked into gear to claim a seven-try win that will please Stuart Lancaster.
When Wales had possession they were guilty of forcing passes, and their high error-count merely played into Argentina's hands. The only positive note for a disjointed home team was that they were in front approaching the last quarter of the match.
Italy warmed up for the visit of two heavyweights in the coming weeks with an unconvincing win over a feisty Tongan side.
The Americans ran in six tries to build a commanding lead by the hour mark but let their intensity drop in the final quarter to allow the Russians to bring a semblance of respectability to the scoreline.
The Pacific Islanders dominated from the start, scoring five tries — including four for debutant wing Robert Lilomaiava — to cruise into a 42-0 lead.
In a performance worthy of their status as the top-ranked team in the world, New Zealand weathered an early storm to overturn a half-time deficit and eventually run out comfortable winners.
Though honours were shared by the trans-Tasman rivals, Australia will treat this result as a mental victory seeing that Robbie Deans' troops weren't given a chance in hell of matching the All Blacks prior to kick-off.
It wasn't pretty but one feels the Wallabies won't mind that as the success supersedes a forgetful period of injuries and off-field issues (hopefully).
The All Blacks produced their best performance of the year to demolish los Pumas, scoring seven tries including a hat-trick for Cory Jane and two for his fellow wing Julian Savea.
The Springboks led 14-3 at the interval but the Wallabies were lucky not to be much further behind. Two tight calls from the TMO meant the home side did not have the four-try bonus point by half-time, but Heyneke Meyer's men secured a full house of points after the break as Bryan Habana bagged a hat-trick to add to earlier scores from Zane Kirchner and Francois Louw.
The All Blacks, unbeaten in 14 Tests, outscored the Springboks two tries to one for a win that sees them take a commanding lead in the competition.
The Pumas looked on course for a famous win after two quick-fire tries saw the tournament newcomers lead 19-6 with just over a quarter of the match remaining.
The world champion All Blacks, number one in the world and undefeated since beating France in the RWC final last year, were hanging on the ropes for three quarters of the match until two quick-fire tries secured a hard-fought win.
Both sides desperately needed a win to have any chance of catching the All Blacks in the race for the trophy, and were under pressure to deliver.
The outcome is the Pumas' best result in 15 Tests with the Springboks, but the hosts will nevertheless be bitterly disappointed after leading the match until the 65th minute.
The All Blacks once again underlined their status as world champions by keeping their trans-Tasman rivals scoreless for the first time since 1962.
