Cricket team's legs (6)
I believe the answer is:
eleven
I believe this clue is a double definition.
'cricket team's' is the first definition.
(a cricket team has eleven players)
'legs' is the second definition.
(eleven is 'legs eleven' in the game bingo)
(Other definitions for eleven that I've seen before include "Number on a soccer team" , "Cricketing side" , "Number of pipers piping" , "Late" , "Bingo's "legs"?" .)
