Asche will bat sixth in the lineup and serve as the White Sox's DH in Monday's season opener against the Tigers.
Asche, who also offers the ability to play third base and the corner outfield, will likely split duties at DH with Matt Davidson initially, with the former seeing the bulk of the starts by virtue of being the left-handed hitter of the two. The 26-year-old will probably have to produce before generating much interest in mixed leagues after slashing .213/.284/.350 across 218 plate appearances with the Phillies in 2016.
