Walsall stand on the brink of the Great Escape after a stunning win over Charlton.

Goals from Will Grigg and Julian Gray kept the Saddlers one point ahead of fourth-bottom Dagenham & Redbridge and sent the League One survival battle to the last day.

Walsall go to Southampton while the Daggers – who beat Carlisle 3-0 today – travel to Peterborough knowing they must beat the Saddlers’ result to survive.

Bristol Rovers’ 1-1 draw with Sheffield Wednesday all-but-confirmed their relegation due to their inferior goal difference.

Walsall’s win owed everything to a first-half attacking verve and second-half nerves of steel as they rode out brief Charlton pressure.

They bossed the former Premier League outfit to complete a notable double – following a 1-0 win at the Valley in December.

The Saddlers were unchanged from Monday’s 1-1 draw at Oldham and immediately took the game to the Addicks.

But they should have fallen behind after just two minutes, when Paul Benson was left unmarked only to power his header from Nathan Ecclestone’s cross against the base of the post.

It was a huge let-off and the Saddlers almost made the most of it 10 minutes in, when goalkeeper Rob Elliot saved well from Jon Macken and Simon Francis blocked Gray’s follow-up.

Walsall were playing with a tempo befitting to the occasion and Matt Richards drove just wide from 25-yards following Gray’s quick free kick.

Jordan Cook was the next to have Charlton sweating after unleashing a rasping effort from 30-yards which forced Elliot into a sprawling save after 15 minutes.

But Walsall were almost pushed for some slack defending when Therry Racon sliced wide at the far post.

‘Shoot on site’ had seemingly been the message for the dressing room, as Marc Laird and Macken screwed strikes wide.

But Walsall needed to take their chances and – despite dominating – survived a scare on 27 minutes when Michael Stewart cut in from the left and drilled wide.

The Addicks were there for the taking, though, and Walsall finally got their first-half rewards on 33 minutes.

Richard Taundry’s cross from the right was knocked down by Macken for Grigg to guide the ball low into the corner from 16-yards.

Laird’s acrobatic volley dipped over minutes later as Walsall searched for a second but they were vulnerable on the break and Racon twice tested goalkeeper Jimmy Walker with low efforts.

The Addicks came out fighting after the break and Benson headed over as the tension levels rose at the Banks’s Stadium.

Walsall soaked up the pressure and aimed to hit the visitors on the break and almost doubled their lead on the hour, when Cook’s stunning 25-yard drive smacked off the bar.

It only increased the pressure as the Saddlers hung on to their slender lead – knowing they needed a second for some breathing space.

Darren Byfield replaced scorer Grigg with 15 minutes remaining and, two minutes later, Walsall got the priceless second.

The Addicks were stretched at the back and Cook burst clear to cross for Macken, whose shot was saved by Elliot, but Gray stroked in the rebound from 10 yards to wrap up the points.
