"He was great," Guillen said. "To me it was more important where the ball's going and how he throws it than getting the guy out. He had good at-bats, hit the ball pretty good in two at-bats."
Guillen gave credit to White Sox first-base coach Harold Baines, Minor League outfield instructor Daryl Boston and Minor League baserunning coordinator Devon White for putting in extra work to help Viciedo get acclimated at his latest position.
"One thing about Viciedo, he has matured a little bit," Guillen said. "He came into camp in shape ready to play. Before, the last two Spring Trainings, we had to fight with him. It's not easy to go to Spring Training and have to lose weight. It's not.
"All of a sudden you get tired during Spring Training and your body's not acting the same way. And to be around JP [Juan Pierre] that helps. This guy is a workaholic."
