Pirates place C Snyder on disabled list

The Pittsburgh Pirates have placed Chris Snyder on the disabled list with a herniated disk, meaning the team's top three catchers currently are injured. Snyder is scheduled for back surgery on Friday. To take his place on the roster, Pittsburgh purchased the contract of Wyatt Toregas from Triple-A Indianapolis - where he was hitting .034 (1 for 29). Snyder left Wednesday's game after sliding awkwardly into second base trying to stretch a single during the second inning. Former starter Ryan Doumit (left ankle sprain) has been out since May 30, and the organization's No. 3 catcher, Jason Jaramillo, is on a minor league disabled list with an elbow injury.
