According to another MLB source with knowledge of Young's workout at Pirate City, manager Clint Hurdle was most impressed with the conditioning of the first baseman-outfielder -- who went by the nickname "Da Meat Hook" during his playing days and weighed in at 295 pounds with the Nationals in 2008, his last year in the Majors.
Young is said to have shed more than 70 pounds, and showed the Pirates enough to make them think he could provide a team with a veteran bat off the bench.
The Bucs, however, are satisfied with the players already lined up to be in camp.
In addition to Casey McGehee and Garrett Jones, who will compete for the first-base job, non-roster invitees will include Nick Evans, who logged 45 games at first base last season with the Mets, and Jeff Clement, the former No. 1 Draft choice of the Mariners whose career has been repeatedly stalled by injuries.
