Andy Carroll scored his first goals since March as West Ham United came from behind to beat Swansea City 3-1 on Sunday and claim third place in the Premier League.
Wilfried Bony put Swansea ahead against the run of play, but Carroll, who missed the first three months of the season with an ankle injury, scored twice before teeing up substitute Diafra Sakho to lash in a late third.
Swansea finished the game with 10 men after goalkeeper Lukasz Fabianski was shown a straight red card for impeding Sakho shortly after Carroll's second goal.
Victory took Sam Allardyce's side up to third place, their highest position since 1999, ahead of fourth-place Southampton's meeting with fifth-place Manchester United at St Mary's on Monday.
Swansea, who have gone 58 years without a league win at Upton Park, remain eighth. Swansea struck from their first attack of note in the 19th minute.
Jefferson Montero exchanged passes with Gylfi Sigurdsson and motored to the byline on the left before pulling the ball back for Bony to steer home his seventh goal of the campaign.
After venturing forwards from right-back, Carl Jenkinson whipped an inviting cross to the far post and Carroll climbed highest to guide a fine header into the top-right corner, 22 minutes after Swansea took the lead.
West Ham introduced fit-again top scorer Sakho at half-time and continued to boss proceedings, although Bony almost restored Swansea's lead on the hour with a vicious shot that grazed the crossbar.
The game was in the balance, but a two-minute spell mid-way through the second period tipped the momentum decisively in West Ham's favour.
Carroll put the hosts ahead in the 66th minute, eluding Swansea's markers to meet Downing's drilled corner with a powerful header that visiting midfielder Leon Britton could only help into the roof of the net.
Moments later, Sakho was impeded by Fabianski, who had come rushing out of his goal, and although the Senegalese striker managed to roll a shot against the post, referee Chris Foy elected to send the Swansea goalkeeper off.
Swansea manager Garry Monk sent on reserve goalkeeper Gerhard Tremmel in place of Britton.
Sakho made no mistake three minutes from time when he gathered a flick-on from Carroll before blasting past Tremmel to register his seventh league goal of the season.
Elsewhere on Sunday, Aston Villa came from behind to beat Leicester 2-1 at Villa Park and move into 11th with their second consecutive win. The result leaves the visitors rock bottom of the Premier League and manager Nigel Pearson under increasing pressure.
Leonardo Ulloa had given Pearson's side the lead after 13 minutes after tapping home Brad Guzan's fumbled save.
But the lead didn't last long, Ciaran Clark levelling with a fine steered header to the delight of the home fans.
Alan Hutton went on to score Villa's winner after some fine work from Gabriel Agbonlahor and Christian Benteke with 19 minutes remaining.
Hutton nearly turned villain 8 minutes later after the Scot clashed with Leicester's Paul Konchesky. The former England left-back saw red for his part in the scuffle but Hutton, who seemed to instigate the disagreement, got away with just a booking.
