LONDON (Agencies) - Chelsea kept alive its faint hopes of retaining the Premier League title with a 3-1 win at West Bromwich Albion on Saturday that moved the defending champions to within eight points of leader Manchester United. With United playing local rival Manchester City in the semi-finals of the FA Cup, Chelsea recovered from 1-0 down at the Hawthorns through goals by Didier Drogba, Salomon Kalou and Frank Lampard. Chelsea now has 61 points with six games remaining, one point behind second-place Arsenal, which hosts Liverpool in todays (Sunday) match. Didier Drogba, Salomon Kalou and Frank Lampard scored Saturday to give Chelsea a 3-1 win at West Bromwich Albion and keep alive the Blues faint hopes of retaining the Premier League title. Peter Odemwingie put West Brom ahead in the 17th minute with his 12th league goal of the season, but the lead lasted only five minutes as Drogba tapped in after fullback Nicky Shorey cleared a cross straight to the Ivory Coast striker. Chelsea led four minutes after that when Kalou scored with an angled shot following goalkeeper Scott Carsons failure to push away Drogbas long-range shot, and Lampard rounded off a slick counter attack in the 45th. Odemwingie raced clear and lifted the ball over goalkeeper Petr Cech to put West Brom ahead, but the 33-year-old Drogbaselected ahead of out-of-form Fernando Torres as the focal point of Chelseas attackequalized with his 11th Premier League goal of the season. Ashley Cole released Kalou down the left and his cross eluded goalkeeper Scott Carsons attempted interception and went all the way across goal to Shorey. The defenders mis-hit clearance fell to Drogba, who lashed the ball into the net. It was Drobgas shot that led to Kalous goal for 2-0, but Chelseas third goal was its best. From a deep position, Drogba released Florent Malouda down the left wing and the France international pulled the ball back to Lampard. The England midfielder, who had a 30-meter (shot) tipped over the bar before he extended the visitors lead, had time to place his shot past Carson. Wigan beat Blackpool In Blackpool, Wigan climbed out of the Premier League relegation places with a potentially crucial 3-1 over Blackpool on Saturday, which sent the Seasiders into the drop zone. Hugo Rodallega set Wigan on its way with a third-minute goal and Charles NZogbia doubled the advantage in first-half stoppage time, dribbling past two defenders before slotting into the far corner. It was 3-0 in the 67th when Mohamed Diames speculative shot took a huge deflection off Neal Eardley to beat Blackpool keeper Matt Gilks, and though DJ Campbell pulled one back in the 83rd, it wasnt enough to save Blackpool. The Seasiders sank to second from bottom, with Wigan, which started the day bottom, moving up to 17th. Blackpool routed Wigan 4-0 on the opening day of the season as the newly-promoted side made a bright start to life in the top tier, but Ian Holloways side has now won one of its last 13 league games. Blackpool has conceded the most goals in the Premier League and has the worst home record. Defensive mistakes made Wigans life easier. Craig Cathcart slipped as NZogbia passed the ball to Rodallega, who scored his seventh league goal of the season. Charlie Adam was dispossessed by Diame in the leadup to the second goal, although NZogbia still had plenty of work to do. Birmingham win Birmingham eased its fear of relegation while extending Sunderlands slump with a 2-0 victory in the English Premier League on Saturday. Midfielder Sebastian Larsson took advantage of a mistake in defence to score just before halftime in his 100th EPL game, and then Craig Gardner added his team-leading ninth of the season in the second half. Birmingham jumped in the standings above Sunderland, which has gone nine straight games without a win. Only a few months ago, Sunderland was contending for a top-six position and dreaming of qualifying for European play for the first time. Aston Villa score win In London, Gabriel Agbonlahor headed an injury-time winner against West Ham to move Aston Villa up to ninth in the Premier League with a 2-1 win and leave the opposition stuck in the relegation zone. Agbonlahor met Ashley Youngs cross from six yards in the first minute of added time to deny West Ham a point in its attempt to avoid the drop. Robbie Keane had given West Ham the perfect start with a goal after three minutes, but Darren Bent headed in a Luke Young cross to make it 1-1 in the 36th and Villa had a host of chances in the second half before Agbonlahor eventually found the net. Villa moved seven points clear of the relegation zone, while West Ham is two points from safety in 19th.
