Kyle McCulloch threw seven scoreless innings Saturday for Single-A Winston-Salem.
He struck out eight. McCulloch, a 2006 first-round pick, is 4-5 with a 3.50 ERA, 78 H and 51/26 K/BB in 72 IP. His lack of upside is one reason the White Sox have made acquiring bigger arms a priority this year. Still, he might have a future as a No. 4 starter.
