San Diego has been crazy busy at this year's trade deadline, with Williams being the last in a long line of moves to bolster the big-league squad. He will probably pitch in a setup role with the Padres.

The Mariners were using Williams as their closer this season, but he was probably not their long-range solution in that role (especially for a team with plenty of holes throughout the roster). So, they did well to move him.

Williams loses all fantasy value in those leagues where saves are important and holds are not a stat category. Otherwise, he should continue to be relatively useful in some formats.
