Evan Longoria expects to win immediately with the San Francisco Giants, whose run of success in even years is well documented - and the club's new third baseman knows all about that. The Giants' brass realizes adding Longoria to the lineup and an already-talented infield gives San Francisco a far better chance of bouncing back from a surprising last-place season in the NL West. An offense-producing third baseman the Giants sought this winter, Longoria was traded from Tampa Bay on Wednesday for outfielder Denard Span, star infield prospect Christian Arroyo and two minor league pitchers.
