Seoul Gazette - Lock Petti to become latest Argentina centurion in Nations Championship Test 

Petti, 31, follows in the footsteps of second-row partner Matias Alemanno, who reached the landmark in last week's campaign-opening loss to Scotland in Cordoba, having made his Test debut in 2014.

Head coach Felipe Contepomi has made five changes for Saturday's game with props Boris Wenger and Tomas Rapetti coming in among the front-row.

Mayco Vivas drops to the bench but Pedro Delgado is out of the matchday squad.

Back-rower Marcos Kremer replaces co-captain Pablo Matera at openside flanker while centre Justo Piccardo and winger Bautista Delguy take the places of Faustino Sanchez Valarolo and Rodrigo Isgro.

Wales head coach Steve Tandy has named Louis Rees-Zammitt on the bench with Ellis Mee taking the speedster's place in the starting lineup.

Tandy has made two other alterations from last weekend's win over Fiji as Sam Costelow is handed the No 10 shirt with Dan Edwards out of the 23 completely and James Botham replacing Alex Mann at blindside flanker.

Former England under-20s back-rower Kane James could make his Test debut, having been selected on the bench.
