From the Post:
Wilder, who has been in his current position for the last two seasons, oversees Chicago's minor league and Latin American operations.
Before joining the White Sox, he spent 2000-03 with the Milwaukee Brewers, first as vice president of player personnel and later as a special assignment scout. In 2000, he was a member of the USA Baseball selection committee which put together the team that won the gold medal at the Sydney Olympics.
Before his time in Milwaukee, Wilder served as the Chicago Cubs' farm director for three seasons (1996-98) and assistant general manager for one year (1999). He also worked in various capacities, mostly in scouting, for the Atlanta Braves from 1991-95.
Decent pedigree, although I don't know much about him.
Here's an article from back when the Red Sox were looking at him:
"There are a lot of people in the game who have great respect for not only what he has done but the kind of person he is," Kapstein said. "Kenny Williams and Dave Wilder are the two leaders of that franchise in terms of putting that club together. And we all saw what that club did."
