It was a case of the sublime and the ridiculous at Upton Park, where Teddy Sheringham's class finish and a controversial decision by the assistant referee saw West Ham beat 2-1 Middlesbrough.

Sheringham came off the bench to net with his first touch after 65 minutes before the assistant on the far side ruled Chris Riggott had deflected the ball over the line - despite replays showing goalkeeper Mark Schwarzer had kept it out.

While West Ham were just about good value for their first Barclays Premiership win in four attempts, Steve McClaren's men suffered from their European endeavours in midweek, failing to really test opposing keeper Shaka Hislop, with a late header from substitute Franck Queudrue proving little consolation.

After a promising opening from the home side, they almost pressed the self-destruct button on eight minutes.

A loose pass along the West Ham back-line from Anton Ferdinand put Danny Gabbidon in trouble, and he brought down Gaizka Mendieta some 25 yards out as the Boro midfielder looked to skip clear.

However, the Spaniard's strike from the resulting free-kick was horribly high and wide.

Mendieta was felled again, this time by Paul Konchesky, in a similar position. Fabio Rochembach took responsibility himself, but could only drive a low effort into the wall.

Mendieta then floated a deep cross over from the right, which found its way through to Massimo Maccarone at the far post, but the striker's header flew high into the stands.

West Ham had their first notable attack after 16 minutes when Yossi Benayoun twisted his way into the penalty area, and struck a low effort goalwards, which was blocked by an alert Gareth Southgate.

Bobby Zamora - preferred in attack to Sheringham - had a great chance to open the scoring after 21 minutes when a fine pass from the impressive Benayoun opened up the Boro defence.

The ball dropped to the Hammers striker ahead of his markers on the edge of the penalty area, but he could only guide a tame, first-time effort straight at Schwarzer.

In the 25th minute, Southgate had to be replaced following an awkward fall, with Queudrue coming on.

West Ham were pressuring well, and Hayden Mullins flashed an effort just wide of the right-hand post when the ball broke to him 15 yards out.

Hammers captain Nigel Reo-Coker thought he had opened the scoring on 31 minutes when he back-heeled Marlon Harewood's low centre in from close range, but was flagged offside - which looked a correct, if marginal, call.

Then, on the counter-attack, Rochembach flashed a low effort across goal after getting in down the left channel, which Hislop did well to scramble away.

With four minutes to go before half-time, Mendieta found some space around 25 yards from goal, and was unfortunate to see his well-struck shot drift just wide of Hislop's left-hand post.

George Boateng's 15-yard strike from a well-worked corner on the right was blocked bravely by Ferdinand in stoppage time.

Following a slow start to the second half, Rochembach, on 52 minutes, clipped an effort goalwards from the edge of the area but Hislop was well placed to collect comfortably.

Queudrue then flashed a deep centre from the left across the area, which was just too far ahead of Maccarone.

At the other end, Benayoun could not guide Konchesky's cross from the left on target, his header flying wide from 10 yards.

The Hammers upped the tempo as the hour approached, another centre, this time from Matthew Etherington on the right, flying across the area with no-one able to make a vital connection.

Determined runs by Harewood and then Zamora on the edge of the area, saw the ball break to Benayoun.

The midfielder weaved his way towards the by-line, drew the keeper and slotted the ball back goalwards, but Queudrue was on hand to clear off the line.

After 65 minutes, Sheringham was sent on for Zamora - and with his first touch, the former England man put West Ham ahead.

Konchesky made ground down the left flank, and cut the ball back into the penalty area, where Sheringham was in the perfect position to slot home a low strike, which took a slight deflection past Schwarzer.

The Hammers went 2-0 up in controversial fashion with 15 minutes left.

Konchesky whipped in a free-kick from the left, which deflected off Riggott.

Although wrong-footed, Schwarzer clearly got his hands down to make the save on the line but the assistant referee on the far side ruled the ball had gone in - much to the disbelief off the whole Boro side and bench.

Boro pulled a goal back with three minutes left when Queudrue headed in a corner from the left, but West Ham closed out the remainder of the match without much concern.
