The crawling hand

It's hard to figure out what that disembodied glove and hand is doing on Mike Torrez's card. If someone is leaning on the dugout wall next to him, it would seem to be an awkward angle, one that might even do damage to one's wrist. And there isn't enough room in the dugout (appears to be Tiger Stadium's, which was very small) for someone to be sitting above Torrez.

Perhaps it really is a disembodied hand crawling along the dugout wall, which would explain Torrez's look of horror.
