10:40pm: It is a minor league contract, confirms Troy Renck of the Denver Post (via Twitter).
9:52pm: The Rockies have agreed to a deal with catcher Yorvit Torrealba, reports Jon Heyman of CBS Sports (Twitter link). The contract is for one year, as Torrealba revealed himself on his Twitter account (MLB.com's Thomas Harding provides the translation). Harding reported earlier this week that the Rockies had offered Torrealba a minor league deal. Torrealba is represented by MDR Sports Management.
This is Torrealba's second stint in Colorado after playing for the Rockies from 2006-09. There were rumors that the Rockies were looking to acquire Torrealba last summer in the midst of a busy year for the 34-year-old catcher --- he bounced around between the Rangers, Blue Jays and Brewers and hit a combined .227/.293/.330 in 218 plate appearances.
Ramon Hernandez is the Rockies' incumbent backup catcher (behind starter Wilin Rosario) but he underwent hamstring surgery last September and is scheduled to play in the World Baseball Classic. Torrealba is on board to provide depth through Spring Training while Hernandez is away and potentially fill in should Hernandez suffer a fitness setback.
