<p>Wawrinka needed just one game to complete victory, breaking the former world number one's serve after bad light halted play on Sunday with the score stranded at 4-6, 6-4, 6-7, 6-4, 5-3. <br /><br />The world number 19 Swiss, who went down to Bernard Tomic in the opening rubber and had struggled on the grass courts at Sydney Golf Club, had also taken pain-killing injections for a foot injury before his fighting win over Hewitt. <br /><br />Wawrinka teamed up with Federer in a narrow loss in the doubles on Saturday and was delighted to play a decisive part in the 3-2 victory after his more illustrious team-mate won both his singles rubbers against Hewitt and Tomic. <br /><br />“It's amazing to be in the same team but for sure in Switzerland it is never easy because it doesn't matter what I am going to do or which ranking I am going to have because it's never going to be enough for Swiss people because they always look to Roger -- but that's okay,” Wawrinka said. <br /><br />Hewitt's loss condemned Australia to their fourth straight defeat in the World Group play-offs.</p>
