pitch a hand

[Garin]

Hello, everyone!
In a Batman comics, Captain Gordon is asking Batman for help. There are eight girls missing and Gordon says: "I was hoping you’d pitch a hand before we hit double digits." Is "to pitch a hand" just a more colourful way of saying "to help" or does it mean something different?

Yes, it means much the same as "pitch in".

pitch in
