According to Adam Rubin of ESPN New York, following the memorial services Friday night, Fred Wilpon presented Gary Carter's wife, Sandy, with a No. 8 patch.
The patch will be worn by all Mets players this season, as well as during Spring Training.
David Lennon of Newsday said the patch will be a "No. 8 patch over a home-plate cutout."
As soon as an image is available, I'll be sure to post it.
