In an injury that I thought would happen more frequently, Mike Matheny of San Francisco has gone on the disabled list with a concussion. On Wednesday, Matheny took a foul ball off the mask estimated at 100 mph.
Eliezer Alfonzo was recalled from AA Connecticut. Todd Greene will take over the regular catching role. The Giants and Mets are playing a doubleheader Sunday so Alfonzo should see some action right away.
