The Giants added IF Ryan Theriot and RP Guillermo Mota to their roster, bringing the total to 40. Centerfielder Justin Christian was designated for assignment, according to a tweet from the San Jose Mercury News.
Theriot agreed to a one-year deal worth 1.25 million with the Giants on Jan. 27. The 32-year-old utility infielder hit .271 for the World Champion St. Louis Cardinals.
Theriot is a .282 career batter over seven MLB seasons.
The Giants made it clear they wanted to return Mota after he pitched 80.1 innings with a 3.81 ERA in his 13th MLB season last year, but the talks have been stalled for some weeks by specifics in contract language.
Mota holds a career ERA of 3.91 with a record of 39-44.
Christian played 18 games with the Giants at the conclusion of last season, and showed some promise with speed and defense. But the Giants acquired Angel Pagan and Melky Cabrera to roam AT&T Park's vast outfields this offseason, leaving no room for 31-year-old prospect Christian.
If he clears waivers, he could end up with the Giants Triple-A squad, the Fresno Grizzlies.
