Derek Jeter & Hannah Davis: Super Good Looking Wedding Photos (GALLERY)

Derek Jeter tied the knot with Hannah Davis in style ... that's for sure.

Their marriage Saturday in Napa was supposedly casual, but you can't tell from the photos. She wore a Vera Wang gown. Not clear what he's wearing, but it looks good.

100 people watched as the former baseball great and the Sports Illustrated model tied the knot.

Congrats.
