PREMIER LEAGUE ROUND-UP:Long-throw specialist Rory Delap continued his domination of Premier League defences, setting up both goals as Arsenal's season took another turn towards crisis with a 2-1 defeat.
Republic of Ireland international Delap, whose deadly delivery from the touchline has already proved crucial to the Potters' hopes of survival, found Ricardo Fuller after 11 minutes, then helped set up Seyi Olofinjana for the hosts' second before a defected Gael Clichy effort reduced arrears.
It was a case of bad to worse for Arsenal after the dramatic 4-4 draw with Tottenham in midweek and a red card for Robin van Persie, coupled with injuries to Emmanuel Adebayor and Theo Walcott, made it a grim day indeed for Arsene Wenger.
Emile Heskey ended Wigan's miserable run of four defeats and left them singing in the rain with a late, late winner at drenched Fratton Park
For new manager Tony Adams and his Pompey braves it was just plain wet winter misery as they went down 2-1.
Papa Bouba Diop gave away his second penalty in four days when he brought down Wigan's Titus Bramble for Amr Zaki, the prolific on-loan Egyptian ace, to fire the penalty past David James just seconds before half-time.
After a whole host of near misses substitute Niko Kranjcar appeared to have saved a point for the new boss with an 82nd-minute strike but Heskey pounced even later to snatch the points.
Keith Andrews scored his first goal for 10-man Blackburn to salvage a point in a 2-2 draw against West Brom at The Hawthorns.
Andrews drilled a low 20-yard cross-shot past Baggies goalkeeper Scott Carson.
Striker Benni McCarthy put Blackburn ahead from the penalty spot before being sent off for two bookable offences.
Goals from Roman Bednar and Ishmael Miller looked to have sealed victory for Albion before Andrews' late strike.
Mido came off the bench to help sluggish Middlesbrough claim a share of the points in a 1-1 draw with West Ham at the Riverside.
The visitors had dominated large periods of the game with some enterprising play and had taken a deserved lead in the 21st minute when Hayden Mullins volleyed home.
But second-half substitute Mido, a replacement for the lacklustre Afonso Alves, smashed a 83rd-minute free kick past Hammers goalkeeper Robert Green.
Everton finally look to have got their season going after Louis Saha's first goal for the club secured a late victory over former club Fulham at Goodison Park. The French striker came off the bench after 61 minutes and produced the one moment of genuine class from a scrappy match to take Everton's points tally for the week to seven.
Saha netted with a powerful header just three minutes from time, his first goal in the Premier League since February.
