Luckily for Crabb, Cragen never was actually an exemplary fighter—good enough to hold his own, sure, but it was Tom who was the boxer—and she has the element of surprise.

So when she flashes a lopsided smile at Valdis and then ducks through the fence to tap him on the shoulder, he gets only a split second to register the familiar face (in improbably quickly changed clothes?) before he's being hit with a right hook hard enough to send him sprawling to the ground.

The crack is probably his glasses, this time.

Probably.
