**Hugo Keenan scored a hat-trick of tries as Leinster came from 16 points down to claim their first Guinness PRO14 Rainbow Cup win with a 50-21 victory over provincial rivals Connacht at the Sportsground.** Stung into action by Connacht’s strong start, Leo Cullen men’s reeled off tries from Keenan (2), James Tracy, Ross Molony and Cian Kelleher to lead 33-16 at half-time. With last week’s Heineken Champions Cup semi-final defeat to La Rochelle still raw, 2021 British and Irish Lion Andrew Porter, Scott Fardy and player of the match Keenan took their side’s haul to eight tries while Peter Sullivan added to Caolin Blade’s earlier touch down for Connacht. Number eight Jack Conan, another of Leinster’s Lions picks, went off injured during the first half but it looked a precautionary withdrawal.
