NAPA, Calif. (AP) The Oakland Raiders signed general manager Reggie McKenzie to a four-year contract extension.

Owner Mark Davis announced the move Friday night in front of about 100 former Raiders players. Davis said it was time to ''reward'' McKenzie for the job he had done in his first three years with the team.

McKenzie was originally given a five-year contract back in 2012 to run the team after the death of longtime owner Al Davis. The Raiders struggled at the start as McKenzie tried to rebuild the organization, winning just 11 games his first three seasons.

But a few strong draft classes and the hiring of coach Jack Del Rio last year helped Oakland improve to 7-9 in 2015 and the Raiders are expected to contend in the AFC West this year.
