Blanco, 26 in April, posted a line of .252/.303/.341 in 53 games (138 PAs) for the Cubs last season, while playing plus defense at second base, but below average at shortstop (warning: small sample sizes). Blanco's .644 OPS from last season is directly in line with his minor league numbers.
Wittenmyer writes that Blanco was out of options and out of opportunities to make the club this spring. The Rangers have been looking for a back-up infielder since having to void Khalil Greene's contract earlier this spring due to his ongoing struggles with social anxiety disorder.
Blanco is the third infielder acquired by Texas recently. On Wednesday, they traded Edwar Ramirez to the A's for Gregorio Petit, and earlier in the spring claimed Hernan Iribarren off waivers from the Brewers.
