Middlesbrough clinched a home FA Cup quarter-final with Manchester United after triumphing in a penalty shoot-out against Tony Mowbray's side at The Hawthorns.

Albion's January signing Sherjill MacDonald missed the vital spot-kick in sudden death as Boro booked a place in the last eight for the second successive season.

Boro's Dong Gook Lee and Albion's Neil Clement had also failed from 12 yards after the game had ended 1-1 after extra-time.

West Brom dominated the first period, producing some fluent and incisive football in front of England coach Steve McClaren, with Jason Koumas causing Boro all sorts of problems in the second striker role.

Boro found it hard to cope with Mowbray's side despite Jonathan Woodgate impressing and would have been relieved to be only one goal in arrears at the interval - a fourth of the campaign from Darren Carter.

But it was a different story after the break with Gareth Southgate's substitutes, James Morrison and Stuart Parnaby, making a telling contribution while Mark Viduka and Ayegbeni Yakubu also came more into the game.

It took Mark Viduka's ninth goal since the turn of the year to force the game into extra-time before the shoot-out drama.

West Brom showed enough quality in the opening 45 minutes to suggest they can compete in the Barclays Premiership if they gain promotion.

But Mowbray will be wondering just how much energy his side will have left in the tank for Saturday's crunch home meeting with Sunderland, particularly after playing for most of extra-time with 10 men after Nathan Ellington's red card.

Baggies defender Paul McShane produced a superbly-timed tackle to halt Yakubu in the early stages but the opening half was dominated by the home side.

Richard Chaplow's shot was gathered at the foot of a post by Brad Jones - deputising for back injury victim Mark Schwarzer - and Ellington drilled a shot into the side netting.

Then a deep inswinging corner from Carter picked out McShane at the far post and his powerful header was turned over by Jones.

The Boro 'keeper beat out a fierce drive from Ellington after Carter had opened up the visitors defence with a 40-yard crossfield pass, and then went down to cling onto Zoltan Gera's glancing header from a Paul Robinson centre.

After 25 minutes, Carter deservedly put West Brom in front.

The former Birmingham midfielder was in yards of space when he collected a crossfield pass from Ellington some 25 yards from the Boro goal.

But Jones still appeared to be flat-footed and made no sort of attempt to dive as Carter curled his low shot into the corner of the net.

Albion keeper Dean Kiely made his first meaningful save when he held onto a low drive from George Boateng away to his left.

But West Brom were quickly back on the offensive after the break and former Boro winger Greening cut in from the left and saw a powerful drive batted away by Jones for a corner.

The impressive Koumas curled a free-kick only a couple of feet wide before Southgate made a second switch, replacing Andrew Davies with Stuart Parnaby.

Downing exchanged passes with Yakubu before firing over the bar and after 63 minutes Viduka brought Boro back on level terms.

The over-lapping Parnaby's cross picked out the Australian whose shot took a deflection off Curtis Davies before entering the net.

Mowbray's response was to bring on 21-goal leading scorer Diomansy Kamara and midfielder Robert Koren for Koumas and Chaplow.

Ellington stung the hands of Jones with a fierce 20-yard drive and Yakubu could have won the game for Boro with two minutes remaining of normal time, but his powerful drive was tipped over by Kiely.

The former Charlton stopper then made a vital stop in the closing seconds to deny the third Boro substitute Dong Gook Lee, who came on for Viduka.

Albion were reduced to 10 men after three minutes of extra-time with Ellington given a straight red card by referee Mike Riley after an over-the-top tackle on Parnaby.

Jones was again alert to keep out a fierce drive from a narrow angle by Kamara who was starting to pose more of a threat.

At the other end Kiely was relieved to see Lee stab the ball wide from another threatening cross by Parnaby.
