Livesey worked in various positions for the Yankees from the late 1970s through the early 1990s. This article credits him with helping sign and develop Fred McGriff, Willie McGee, Jose Rijo and Greg Gagne. Livesey was the Yankees' scouting director in the early 1990s. They picked Derek Jeter in 1992 and Mike Lowell in 1995. Andy Pettitte also signed with the Yankees as an undrafted free agent in 1991. After the Yankees fired him, he worked for the Devil Rays from 1998 to 2001, then served as special assistant with the Blue Jays and then the Mets.
Anyway, there are details about Livesey all over the internet, but the specifics are hazy. It's also an open question how much relevance developing Fred McGriff in the early 1980s has to today's game. (This doesn't mean it's not relevant, just that this is all really hard for an outsider to honestly evaluate.)
Livesey is 72. One wonders if the Pirates would have made this hire if they hadn't come under so much fire recently for Kyle Stark and Larry Broadway's relative lack of experience.
