Sunderland took a small step towards Premier League survival after coming from behind to draw 1-1 at home to Stoke on Monday.Former Manchester United defender John O’Shea rescued a point for Paolo di Canio’s side, already a man down after Craig Gardner was sent off, when he struck from close range in the 63rd minute following a corner.Jon Walters gave Stoke a ninth minute lead, reacting first to fire home after his header from Charlie Adam’s cross was blocked.Then, for the second match in a row, Sunderland found themselves down to 10 men after Gardner was shown a straight red card by referee Lee Mason for an over the ball one-footed challenge on Adam.The draw left Sunderland as one of three teams on 38 points (above Norwich and Newcastle on goal difference) and three points clear with two games to play of Wigan, who currently occupy the third and final relegation place.However, FA Cup finalists Wigan will also move to 38 points with two league games left, and intensify a manic battle to avoid demotion to the second-tier Championship, if they win at home to manager Roberto Martinez’s former club Swansea on Tuesday.
