Wuertz and Ascanio have both been getting torched pretty good in Iowa. Ascanio has given up runs in 7 of his last 10 outings, and Wuertz in 2 of his last 3(including a 3 walk inning). You could add Ceda I guess, but he's given up 3 hits and a walk, 2 walks, and 3 hits respectively in his most recent AA outings. There's no clear replacement for Howry's job, unless Lieber is healthy.
