The British and Irish Lions warmed up for their Australian tour in deflating fashion as they fell to a slick and pacey Argentina in Dublin.
In the Lions' first game on Irish soil and debut outing under new head coach Andy Farrell, Argentina scored breakaway tries through Ignacio Mendy, Tomas Albornoz and Santiago Cordero to spoil the pre-tour party.
Mendy and Albornoz's efforts, either side of Bundee Aki's try for the Lions, gave the South Americans an 11-point half-time advantage.
And while the Lions hit back early in the second half through a penalty try and Tadhg Beirne, Cordero displayed rapid pace on the counter to deliver the decisive score 22 minutes from time.
The defeated Lions travel to Australia on Saturday before their opening tour match against Western Force on 28 June (11:00 BST).
