BOSTON - The Boston Red Sox on Thursday confirmed the signing of outfielder Cody Ross to a one-year contract and said right-hander Scott Atchison was designated for assignment to make room on the 40-man roster.

The US$3 million deal for Ross was first reported on Monday, when he told The Associated Press in a text message he still needed to take a physical.

The 31-year-old Ross batted .240 with 14 home runs and 52 RBIs for the San Francisco Giants last season while playing at least 22 games at every outfield position.

Ross was the 2010 NL championship series MVP for the Giants and helped them win the World Series that year after they picked him up off waivers in August.
