Who could take Phillies bench spot with Weston Wilson out

It was announced this weekend that Philadelphia Phillies utility bench player, Weston Wilson, will miss significant time with an oblique strain. With free agency limited, do the Phillies look internally for the final spot and keep Kody Clemens, Buddy Kennedy or Oscar Mercado? Or could they go outside the organization and bring in a player with a proven track record like former Atlanta Braves outfielder Adam Duvall?
