SAN FRANCISCO (Reuters) - The Oakland Athletics continued to revamp their bullpen by agreeing Wednesday to a two-year contract with free agent reliever Brian Fuentes.

The deal includes a club option for 2013, the team said in news release. No financial terms were revealed.

Fuentes posted a 4-1 record with 24 saves in 48 relief appearances with the Los Angeles Angels and Minnesota Twins last year.

The 35-year-old southpaw led the American League in saves in 2009 with 48.

His signing came one day after the Athletics finalized an $8.1 million, two-year deal with Australian-born, right-handed reliever Grant Balfour.
