Jonathan Walters scored two own goals and missed a penalty as Chelsea won 4-0 to inflict Stoke's heaviest-ever Premier League home defeat.
The Irishman planted a diving header into his own net in first-half stoppage time, and again nodded past Asmir Begovic just after the hour mark.
Stoke had never lost a Premier League match by more than two goals at the Britannia Stadium and may feel the result is not a fair representation of a match to which they contributed much.
But Stoke made the early running, with Walters and Kenwyne Jones posing a formidable challenge for the Chelsea back line.
A Walters shot ricocheted to Jones in the seventh minute, but the dreadlocked striker dragged his left-foot effort wide. Walters then managed to hit himself in the face with a volley.
Wilkinson was harshly booked when Hazard made the most of feather-light contact, but was lucky not to see a second yellow card minutes later for a far rougher challenge.
While Stoke had the better of play, it was Chelsea who carved out the clearest chances.
Superb build-up from Ramires and Hazard presented Lampard with a shooting chance on 25 minutes but Begovic denied him brilliantly.
And the Bosnian was in top form moments later to repel a Ba effort as he latched on to a through ball.
Chelsea finished the half strongly, and went in front seconds before the break when Walters - who had Mata lurking behind him - attempted to deal with Cesar Azpilicueta's cross but succeeded only in planting a bullet header past Begovic.
The game's physical edge saw tempers raised on both benches - Benitez and Tony Pulis launched simultaneous angry confrontations with referee Andre Marriner at half-time, leaving the official somewhat bemused.
Stoke made a bright start to the second period. Marriner initially pointed to the penalty spot when Azpilicueta tackled Matthew Etherington - but assistant Sian Massey had rightly flagged for offside.
Then it all fell apart for Stoke. Walters somewhat unluckily nodded a corner past Begovic with Lampard in close attention, before Robert Huth was adjudged to have tripped Mata inside the box - Lampard converted the penalty to put the result beyond doubt.
Begovic made another fine save from Lampard but could do nothing about Hazard's pure left-footed shot that fizzed into the left corner.
Terry came on - preposterously, the departing Mata dutifully delivered the armband to Terry from the excellent Lampard - and almost immediately made a clumsy challenge on Walters to concede a penalty.
But Walters's misery was not over, and he thumped the ball high into the crowd to end a truly calamitous afternoon.
MAN OF THE MATCH
Frank Lampard (Chelsea): If this is his final season, Lampard is going out in style. He produced another fine, controlled performance and scored to move to within eight of Chelsea's all-time record.
