Ryne Sandberg resigned as Phillies manager as Philadelphia struggles with the worst record in the major leagues.

Sandberg quit Friday with a 119-159 career record over parts of three seasons leading Philadelphia. His only full season was in 2014, when the Phillies finished 73-89.

"With some changes at the top looming, I did not want to be in the way of anything happening and progress going forward," Sandberg said.
