Bolton Wanderers are leading Lancashire rivals Blackpool 1-0 at half time in the Championship.
David Wheater headed Bolton into the lead after 15 minutes when he converted Jay Spearing's delivery.
Elliot Grandin went close for the Seasiders on 25 minutes but his effort just missed the target, moments after Neil Danns had squandered a decent opening for Wanderers.
Lukas Jutkiewicz came close to doubling the advantage towards the end of the half, but the former Everton youngster could only fire wide.
