His time with the Phillies marked a resurgence in his career, as he delivered several strong performances and became a dependable starter for the team. Williams' ability to adapt and contribute in various roles was evident throughout his tenure with the Phillies.

Williams continued to pitch in the majors until 2016, with his final MLB appearances coming as a member of the St. Louis Cardinals. Over his career, he played for several teams, including the San Francisco Giants, Chicago Cubs, Washington Nationals, Los Angeles Angels, Texas Rangers, Philadelphia Phillies, and St. Louis Cardinals.
