That's all from today's live commentary - thanks for following the game with us. Report, reaction and ratings on the way.
This would be Sunderland's first away win since April, when they won the Tyne-Wear derby at Newcastle.
Sunderland's relegation rivals Fulham now lead 2-1 at Norwich. Palace are still level at 0-0 at Aston Villa.
Barkley gets the set piece over the wall but Mannone dives to his left to keep it out! Then Jelavic heads the resulting corner towards goal, only to see Borini head the ball off the line! Drama!
Jelavic is fouled by Roberge about 20 yards from goal, and it's another free-kick chance for Barkley...
A big chance for Fletcher but he squanders it! The Scot received the ball in the D from a left-wing cross and attempted to slide the ball under Joel, only to see it go wide.
Everton have had plenty of shots from range, but that was the best yet - Oviedo with the attempt from the left, and Mannone makes a fine diving save.
Replays show a robust Pienaar challenge on Celustka inside the area probably wasn't a penalty, as Sunderland had claimed.
Barkley sends in a bouncing shot from 25 yards and Mannone needs to be alert to push the ball away to the right.
Mannone is down sharply to his left to keep out Lukaku's low bouncing shot which was heading towards the corner.
Another Everton corner as Oviedo's cross from the left takes a deflection off Celustka. Toffees turning the screw - but Mannone saves the header from Jagielka, and Lukaku can't get any power on the follow-up, allowing the Italian keeper to gratefully clutch the ball.
Lukaku is now causing Diakite to worry at the back and the hosts win another corner - but Colback easily heads away a poor delivery.
Barkley's cross from the right is slightly deflected, but Lukaku is adjudged to have fouled Roberge as the ball came over. Lots of booing from the home fans for referee Lee Probert.
Larsson's set piece causes problems in the area and Diakite ends up swinging his boot at the ball - and wins a corner.
We're underway again, and Coleman fouls Borini early in the second half - free-kick to Sunderland wide left.
A change for Everton at the break (46) - Barkley ON, Mirallas OFF. The Belgian leaves due to illness.
We can hear now from Smyther17 on email: "Howard's red card has been coming, Everton have taken chances passing the ball from him in several games this season. This will be tough now. Martinez will need to take a few risks. Lukaku with a double. Everton 2-1."
A very different picture at Sky Bet at half-time - Sunderland are now 8/13 favourites to win the game, the draw is 9/4 and 10-man Everton are pushed out to 9/2.

Half-time: Everton 0 Sunderland 1 (Ki pen 25). Ki's spot-kick, which he won himself in an incident that saw Howard sent off, separates the sides at Goodison.
YELLOW CARD! Barry is booked for a bad tackle on Colback (42). Mirallas has finally returned to the fray.
Still Everton leading in terms of overall possession (61% to 39%), but the Cats are now beginning to make use of their extra man and threaten more.
Double save! Joel badly spills the first effort from Celustka, and it looks like Larsson will just tap in the loose ball - but the Spanish goalkeeper does brilliantly to deny him.
Distin's challenge for the ball from a free-kick is punished, as Sunderland get the chance to clear their lines. Fulham equalise at Norwich, so the Cats are bottom again.
Coleman is nudged by Borini on the right flank but still manages to get his cross in - nothing given by Probert.
Ten-man Everton are moving the ball around and looking for an opening. Mirallas and Lukaku try a one-two on the edge of the box but Sunderland crowd the Belgians out.
That goal has moved Sunderland off the bottom of the table and above Fulham, who are losing 1-0 at Norwich, on goal difference.
Ki says a little prayer after rolling the ball low to the right of substitute goalkeeper Joel Robles and into the corner. 0-1.
Osman stumbled as he attempted to control the short pass from Howard. Ki seized on the ball, took it around Howard and was then brought down by the Everton goalkeeper.
Colback wants a foul for the challenge of McCarthy, but replays suggest the Sunderland man went down theatrically.
Colback is caught by Osman and Sunderland will be able to take a free-kick from within their own half.
Mannone shows some neat feetwork to take the ball around Mirallas in his own penalty area. Then Diakite sweeps up for Sunderland as a cross comes in from the left. Meanwhile, Norwich are 1-0 up on Sunderland's relegation rivals Fulham.
Barry meets the corner with a header at the far post, but the ball is too high and he can only nod it skywards.
A shot on goal from Oviedo - a swerving left-footed effort from around 20 yards, but Mannone tracked the ball well and saved.
A foul in the centre circle by Cattermole, but Sunderland win the ball back quickly and Borini ends up firing over the bar from long range.
Diakite heads away a dangerous right-wing cross from Mirallas. Pienaar gets a flick all wrong on the other flank.
Howard has to stretch to clear the ball from in front of Fletcher on the edge of the area after Jagielka underhit a backpass. That was close!
The referee today is Lee Probert. He was in charge of Sunderland's 3-1 defeat at Crystal Palace at the end of August.
A few words from Sunderland's Jack Colback: "The pressure's off us a little bit. It's a difficult game but one you relish to play in, and we hope to upset the odds. It's been a tough start, but we're confident enough we can get out of it. The fans are always great, they come in their thousands - and we're hoping to send them away with something today."
Here's Jamie Redknapp's Red Hot Tips from Sky Bet - he's backing a 3-1 Everton win at odds of 10/1, and he also fancies Everton -1 at 11/10.
Roberto Martinez speaking before kick-off: "Sometimes you look at the table and you think it'll be a straightforward game - but it's not that from our point of view. Sunderland are a completely different side in the last 10 games. They have a very solid way of performing. They want to get on the ball and impose themselves. They are capable of beating teams like Manchester City and Chelsea." The Everton boss continues: "Confidence is a special word to have in football. But we're still a young group, and we just want to get better and fulfil our potential. Our fans have been incredible at Goodison, and our home record is partly down to them."
Sunderland fan Gareth Growley is feeling optimistic on email. "I know it seems tough but I think Sunderland will win 2-1 today. I can see goals from Altidore and Ki to seal the win. Everton are on a good run, but a run has to come to an end sometime- and I think today is the day."
Victory could move Everton into second spot, but only if Chelsea fail to win at home to Swansea and Arsenal lose at West Ham. The evening kick-off between Manchester City and Liverpool will also be a factor in terms of what position the Toffees find themselves in at the end of Boxing Day. Sunderland need a victory to have any hope of climbing off the foot of the table - their nearest rivals Crystal Palace and Fulham are also away from home, at Aston Villa and Norwich respectively.
Let's check out the pre-match betting. Everton are big 4/11 favourites with Sky Bet to take all three points this afternoon, with Sunderland long shots at 8/1. The draw is priced at 19/5.
Stewart MacLaren joins us from "a warm and windy Torrevieja in Spain" via email. He writes with an air of authority: "Everton will beat Sunderland 2-1 at Goodison Park on Boxing Day with good goals from Bryan Oviedo & Romelu Lukaku."
Time for some pre-match stats, courtesy of Opta: 1. Sunderland's victory over Everton in April ended a run of 16 without a win in the Premier League for the Black Cats against the Toffees (D4 L12). / 2. Everton have not lost a Premier League game on December 26 since 2005 (W3 D3 since then). / 3. The last time that Everton went unbeaten at home in the league for a whole calendar year was back in 1962.
Here's the thoughts of Everton's Sylvain Distin ahead of today's game: "We just want to keep focused on what we're doing so far, which is working hard and playing good football. It's way too early to start thinking about where we could finish. There's always pressure! It's pressure to perform. We've got demanding fans, we are demanding players and we've got a demanding manager as well. Even if things are going well now, things can go bad very quickly." And on the busy festive programme, he adds: "For me, it's always difficult. Christmas time is family time. You don't really want to wake up to go to the training ground on Christmas Day. You have to be professional though - we have an amazing job and that's maybe just one little downside."

Lee Cattermole will captain Sunderland in the injury absence of John O'Shea. Diakite and Roberge have only played together at the back on one previous occasion for the Black Cats - the 3-1 home defeat by Arsenal on 14 September.
And the Sunderland starting line-up: Mannone, Celustka, Bardsley, Diakite, Roberge, Cattermole, Ki, Colback, Larsson, Borini, Fletcher.
Here's the teams in full. First up, Everton: Howard, Jagielka, Distin, Oviedo, Coleman, Mirallas, McCarthy, Barry, Osman, Pienaar, Lukaku.
Sunderland boss Gus Poyet makes four changes following the 0-0 draw at home to Norwich on Saturday. Wes Brown starts a three-match ban, while John O'Shea (shoulder) is not fit to play. As a result, Modibo Diakite and Valentin Roberge both start, along with Jack Colback and Steven Fletcher. Jozy Altidore and Emanuele Giaccherini drop to the bench, while Cabral and El Hadji Ba also feature among the substitutes - meaning no place for Craig Gardner in the 16 today.
Roberto Martinez makes one change to the Everton side that started the 2-1 win at Swansea last Sunday. Leon Osman starts at the expense of Ross Barkley, who drops to the bench. Leighton Baines (toe) is still out. Steven Pienaar and Sylvain Distin are both fit enough to continue, while Nikica Jelavic is on the bench after his hamstring injury. Apostolos Vellios is the man to make way among the subs.
