The Phillies addressed their need for a lefthanded reliever Wednesday afternoon by acquiring Luis Avilan from the White Sox.

Avilan had a 3.86 ERA in 39 2/3 innings with Chicago. The 29-year-old held lefthanded batters to a .214 batting average, .564 OPS, and no homers in 77 at-bats. Since May 21, he has limited lefthanders to a .136 average and no extra-base hits.

The Phillies have had just one lefthander, Adam Morgan, in their bullpen with Austin Davis (lower back tightness) and Aaron Loup (left forearm strain) on the disabled list.

The Phillies sent the White Sox 23-year-old righthander Felix Paulino, who had a 3.91 ERA in 31 games this season working both as a starter and reliever with high-A Clearwater and double-A Reading.

Jose Taveras was designated for assignment to make room for Avilan on the 40-man roster. The 24-year-old returned to double-A Reading last week after missing most of the season with a strained right shoulder.
