Nationals pitcher Rich Hill is expected to compete for a bullpen spot with the team during spring training after being signed to a minor-league contract Friday.
"Veteran, been there, got big league experience," Williams said. "We'll get him in camp, get a good look at him, and let him compete."
Hill posted a 1.69 ERA in 14 appearances with the Yankees in 2014.
"He's ready to go compete," Williams said. "He's here to vie for a spot."
