Russell Westbrook delivered a game-high 41 points as the Houston Rockets defeated Boston 111-110 in overtime to cap a season sweep of the Celtics on Saturday. James Harden, who made just seven of 31 baskets and had five turnovers, gained a small measure of redemption from his poor shooting night by making two late free throws in the win. Harden's free throws gave Houston the lead and then Rockets defence took over forcing Boston's Jaylen Brown to miss his late shot to clinch the victory.
