Theme: Common expressions which include the word “through.” That word is eliminated but is indicated by means of the first word of the expression crossing – in essence “going through” – the rest of the words in the expression.
29-Across (8-Down). Eludes a person’s grasp = Slip (through) one’s fingers
36-Across (3-Down). Has an ad that stands out = Cuts (through) the clutter
52-Across (25-Down). Succeeds when it most matters = Pulls (through) in the clutch*
54-Across (30-Down). Making a feeble effort = Going (through) the motions
(*This answer seems a bit off since I think the usual expression is “comes” through in the clutch not “pulls.”)
