SAN FRANCISCO >> On the day the Dodgers addressed a non-immediate area of need by officially signing free agent infielder Hector Olivera, another immediate need arose.Olivera's six-year, $62.5 million contract is the longest and richest given any to player in the Andrew Friedman era. The 30-year-old said through an interpreter that he can play third or first base in addition to second base, the position he played all his life in Cuba.
