Jon Bickers tucked home a pass by Aaron Churchyard after 15 minutes to give Woodbridge the lead and Mark Roper confidently scored from the spot five minutes later after Nathan Clarke had upended Craig Jennings.

Bickers and Churchyard both headed wide as Woodbridge sought to put the result beyond doubt early in the second period, but Walsham pulled a goal back out of the blue when Will Brown's looping header dropped just inside the far post after 58 minutes.

Jennings shot just wide following a superb long pass from defence by Jamie Scales in the 78th minute and when Matt Musgrove shot just over the bar in the 89th minute it looked as though Woodbridge would go through.

But in the third of five minutes of time added on Brown ran through the middle of the home defence to equalise and so take the contest straight to penalties with no extra time being played.

Although Bickers saw Kevin Bugg save Woodbridge's first attempt, Scales, Ben Garnham and Grant Monaghan all scored. With Mark Wake and Brown being successful but Gary Ross and Neil Gooderham failing to find the net, Tatum converted Woodbridge's fifth kick to confirm their semi-final spot.

Woodbridge team: Tom Ross, Arran Sheppard, Grant Monaghan, Sean Rea (sub David Kempson 85 mins), Mark Roper (sub Danny Tatum 83 mins), Jamie Scales, Aaron Churchyard, Ben Garnham, Jon Bickers, Craig Jennings, Ben Seaman (sub Jack Severy 83 mins). Unused sub: Marcus Garnham.
