A 50/50 vendor made an incredible one-handed grab on Yoenis Cespedes' grand slam with a sign in his other hand
Yoenis Cespedes puts the Mets up 5-0 in the 3rd inning with a grand slam to left field, his 30th HR of the year, but it's the catch by a '50/50' vendor that is the real highlight.
Leave it to Keith Hernandez to wake up long enough to notice that vendor's catch...only after the replay has aired.
