Input: (CNN) -- U.S. coach Eddie O'Sullivan said he "couldn't be more proud" of his players after Thursday's hard-fought 13-6 victory over Russia at the Rugby World Cup in New Zealand. It was the Eagles' first win of the tournament, after a 22-10 defeat to O'Sullivan's native Ireland on Sunday, with a superb 18th-minute try from scrumhalf Mike Petri after proving to be the difference between the two sides in wet conditions in New Plymouth. The Russians, making their World Cup debut, took an early 3-0 lead through a penalty from flyhalf Yury Kushnarev , but the U.S. rallied despite several misses from goalkicker Chris Wyles and the Bears were left with just a solitary bonus point to show for their efforts.The U.S. beat Russia 13-6 to win their first match of the Rugby World CupThe match in New Plymouth was Russia's first at a World CupA converted try from scrumhalf Mike Petri proves the difference between the teamsThe Americans next face Australia, while Russia take on Italy
