Birmingham City have now gone 235 minutes without conceding a goal after playing out a scoreless opening half at Wigan Athletic.
The Blues defence has rarely come under pressure so far in this afternoon's Championship clash at the DW Stadium.
At the other end, Lee Clark's men went close to breaking the deadlock on seven minutes when Paul Caddis crossed low towards Lee Novak, who, on the stretch, was just unable to make a telling contact.
Birmingham continued to impress and Novak's deflected effort forced a decent stop out of Ali Al-Habsi.
Wigan's one moment of inspiration came in the dying moments of the half, as Callum McManaman's low drive was kept out by Darren Randolph.
