The Rangers have officially signed Vladimir Guerrero to a one-year contract with an option for the 2011 season. Guerrero, who passed his physical on Monday in Arlington, will make $5.5 million without incentives. "We're excited to welcome Vlad to the Rangers family," general manager Jon Daniels said in a statement. "This is a guy we've both admired and feared for years from across the field. He's been one of the most dangerous hitters in the game for over a decade. He'll bring a presence to the middle of the order, and a winning pedigree to the club." Guerrero, who will turn 35 in February, will fill the void let behind by Marlon Byrd, who left Texas via free agency.
