Adam Lallana scored a goal in each half as Saints strengthened their promotion credentials today.
Lallana broke the deadlock in the 36th minute, driving in the opener from Rickie Lambert's knockdown.
And he secured the points in the 54th minute following excellent work from Tadanari Lee.
West Ham's failure to win at home to Doncaster completed an excellent afternoon.
