Theriot inks contract with Giants

The Giants increased their infield options Friday, signing free agent Ryan Theriot to a one-year, $1.25 million contract, according to a major-league source.

Brandon Crawford, projected to be the Giants’ starting shortstop in 2012, batted only .204/.288/.296 in 220 plate appearances as a rookie last season. Theriot represents insurance not only for Crawford but for second baseman Freddie Sanchez, who did not play after June 10 due to a dislocated left shoulder.

Theriot, 34, batted .271/.321/.342 for the Cardinals last season, but lost his starting job at shortstop when the team traded for Rafael Furcal at the July 31 non-waiver deadline.
