Phillies send SS Edmundo Sosa (back) to IL

The Philadelphia Phillies placed shortstop Edmundo Sosa on the injured list Sunday with back spasms, while right-hander Seth Johnson was recalled from Triple-A Lehigh Valley.

Johnson, 25, is set to make his major league debut after five minor league seasons. He was acquired from the Baltimore Orioles for left-hander Gregory Soto just before the July trade deadline.

Johnson was a combined 2-7 with a 2.33 ERA in 23 starts for three different minor league teams this season.
