"I've decided to step away from baseball," Weaver said in a statement released on Twitter. "While I've been working hard to get back on the mound, my body just will not allow me to compete like I want to. Many thanks to the Padres' organization for the opportunity to play in the amazing city of San Diego. You have been very professional and respectful during this process, and I really appreciate that.
"I would also like to thank my teammates for welcoming me in with open arms and for all the support throughout the season. I'm excited for the next chapter in life and making up for lost time with my family.
