The Red Sox designated Randy Williams for assignment to create 40-man roster space for Ryan Lavarnway, according to Nick Cafardo of the Boston Globe (on Twitter). The club placed Kevin Youkilis on the disabled list in a related move.
Williams, 35, appeared in seven games for Boston this year, most recently on August 5th. He spent most of the season with Boston's Triple-A affiliate and posted impressive numbers with Pawtucket: a 1.44 ERA with 10.4 K/9 and 4.0 BB/9 in 25 innings of work. Williams has also pitched for the White Sox, Rockies, Padres and Mariners in his five MLB seasons.
