Hosts Sri Lanka look set to extend their dominance over Bangladesh when they open a two-Test series at their happy hunting ground in Galle on Friday. Sri Lanka have won six and drawn one of their last eight Tests on the traditionally spin-friendly Galle wicket, and slow bowlers Rangana Herath and Ajantha Mendis are once again expected to play key roles. Left-armer Herath grabbed 11 wickets in the last Test played in Galle in November to help Sri Lanka crush New Zealand by 10 wickets.
