I don't know. I guess I understood the sentence with 'landed' the same as I would have if someone told me that they'd 'landed a big job'. I wouldn't really say this myself though, although I hear people say 'landed a big catch' when they're talking about fishing.

Landed, with this meaning, is used in the context of successfully enticing someone to give you something. Like hooking a fish with bait.

FWIW, Landing a fish is not the same as hooking it. Landing a fish literally means pulling it to land (or boat).

So landing=catching=scoring.

Depending on the type of fishing, you can still be an underdog to land the fish after hooking it.
