Weathers will be part of the Padres' 60-man summer camp.
The 20-year-old southpaw has a chance to develop into a quality mid-rotation starter down the road, but he has never pitched above Low-A, so he is unlikely to see time in the majors this season. Working on his conditioning and improving the consistency of his fastball will be on his to-do list while working with the Padres' other top prospects this summer.
