Pirates place Chris Snyder on DL

PITTSBURGH -- The Pittsburgh Pirates placed Chris Snyder on the disabled list Thursday with a herniated disk, meaning the team's top three catchers 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.

For now, journeyman Dusty Brown (29 career at-bats) is the Pirates' starter, although manager Clint Hurdle said neither Brown nor fellow 28-year-old Toregas (51 career at-bats) would catch too many consecutive days.

Hurdle also indicated the team was pursuing catching options outside of the organization.
