"The Giants' infield could be ragin' with Cajuns in 2012.

With Mike Fontenot already in the fold, the team agreed Friday to a one-year contract with fellow Louisianan and former LSU teammate Ryan Theriot, who could be a right-handed-batting complement to second-year shortstop Brandon Crawford. Theriot still must pass a physical.

The Giants also announced that Tim Lincecum passed his physical and his two-year, $40.5 million deal is official.

Given Emmanuel Burriss' presence, Fontenot and Theriot, who are old friends and former Chicago Cubs teammates, might compete for one job in spring training, though manager Bruce Bochy said by phone that he would love to have both.

Fontenot ($1.05 million) and Theriot ($1.25 million) have non-guaranteed contracts, which means the Giants could cut either or both during spring training for as little as one-sixth the cost.

Bochy reiterated that Crawford, the Giants' best defensive infielder, will go to camp next month as the starting shortstop, and that is the plan for the season.

However, the Giants feel more comfortable having a shortstop who hits right-handed on the bench to face tough left-handed pitchers. Crawford was 4-for-30 against them as a rookie. Theriot is a .301 career hitter against lefties, .310 last year with St. Louis."
