Chelsea chalked up a much-needed 4-0 victory Saturday as Stoke's long unbeaten home run was brought to a shuddering halt.
The Potters had not lost at the Britannia Stadium in the Premier League since February and have proved formidable opponents for the league's big guns, but this was their biggest home loss since returning to the top flight in 2008.
It began to go wrong in injury time at the end of the first half when Jonathan Walters headed into his own net, and the striker remarkably repeated the trick in the 62nd minute.
John Terry came off the bench in the final 10 minutes for Chelsea in his the first game since suffering knee ligament damage two months ago. He gave away a 90th-minute penalty, and Walters was given the chance to at least score one goal at the right end, but in keeping with the rest of the striker's day he could only find the top of the bar.
Defender Gary Cahill was absent to be at the birth of his son so David Luiz dropped back into defence alongside Branislav Ivanovic, the culprit for both Swansea's goals in the midweek Capital One Cup defeat.
Benitez was once again feeling the heat from the Chelsea fans following the Swansea result and defeat by QPR in their last league game, but his side began positively and only a well-timed tackle from Ryan Shawcross prevented Ramires getting an early shot away.
The Stoke captain showed just why the Potters were so keen to tie him to a long-term deal with some assured play to steady the ship and soon it was the home side that was threatening.
Chelsea was rattled and Cech was grateful to hang on to a header from Steven Nzonzi, who could not get enough power into his effort.
The visitors were struggling to get out of their half but a break in the 25th minute provided them with a great chance as Ba found Lampard running into the area, only for goalkeeper Asmir Begovic to stick out a leg and deny him.
The Bosnian's reputation has soared this season and he was again the savior for Stoke six minutes later as Ba outpaced Robert Huth but could not beat the keeper with the angle tightening, while Wilkinson's crunching tackle stopped Ramires from reaching the loose ball.
Stoke by this point was reduced to half-chances -- a shot on the turn from Jones that was blocked by Luiz and a volley from Glenn Whelan that was straight at Cech.
It looked like the teams would go into halftime all square, but with injury time almost up Cesar Azpilicueta swung in a cross from the right. Mata was poised to convert it but he was beaten to the ball by a diving Walters, who powered the ball past his own keeper.
The striker attempted to make amends after the restart but, though he beat the Chelsea defense, the angle was too narrow to really trouble Cech.
It was an open game and, after Begovic had produced another decent stop to push Ashley Cole's low drive round the post, Nzonzi tested Cech with a fine strike from 25 yards that the Chelsea keeper pushed over the bar.
Shortly after, Stoke thought it had been given a penalty when Matthew Etherington fell under a challenge from Azpilicueta but referee Andre Marriner had in fact awarded a free kick to Chelsea for offsides.
The killer goal arrived in the 62nd minute, and incredibly it was another own goal from Walters. This time Mata sent in a corner and the Stoke striker got his head to the ball just ahead of Lampard.
The Potters were now staring at the end of their long unbeaten home run, and things got worse three minutes later when they conceded a penalty.
Mata broke through and went to ground under pressure from both Huth and Shawcross, though it was the contact from Huth that seemed to prompt Marriner to point to the spot.
Lampard smashed the penalty down the middle, and he should have added a fourth moments later but shot straight at Begovic from point-blank range.
The visitors did manage another in the 73rd minute, though, and what a strike it was as Hazard let fly from 25 yards and the ball rocketed into the top corner.
Two minutes before Torres had replaced Ba, while Terry was given a little over 10 minutes -- and was greeted by his now customary hostile reaction from the opposing fans.
There was still time for Terry to give away a penalty for a foul on Walters, but there was no redemption for the striker.
