Cubs add Theriot to roster Looking to add some offense and speed to a struggling lineup, the Cubs called up second baseman Ryan Theriot from Triple-A Iowa on Monday, sources told the Tribune. The 26-year-old Theriot, a right-handed hitter, was one of the final roster cuts in spring training. He was hitting .309 at Iowa with five stolen bases and 12 RBIs in 110 at-bats. A September call-up in 2005, Theriot went 2-for-13 in nine games with the Cubs. Since Todd Walker's move to first base, Theriot is expected to get some playing time with second baseman Jerry Hairston and infielder Neifi Perez both struggling at the plate.
