Tottenham moved to within three points of the Premier League's top four with a strong display against European qualification rivals West Ham.
Son Heung-min and Harry Kane were involved in all three Spurs goals.
They went ahead when West Ham defender Kurt Zouma guided Kane's cross into his own net under pressure from Son.
Son doubled Spurs' lead after 24 minutes and added a decisive third with two minutes to go, after Said Benrahma had pulled one back for the Hammers.
The hosts got off to a blistering start and could have been out of sight when Son smacked the outside of the post after being teed up by Dejan Kulusevski.
