The Chicago White Sox have made a move to help them remain atop the AL Central, acquiring left-handed pitcher Francisco Liriano from the division rival Minnesota Twins.

In exchange for Liriano the Twins will receive infielder Eduardo Escobar and left-handed prospect Pedro Hernandez. The White Sox enter Sunday 2 1/2 games up on the second place Detroit Tigers.

''He just has to come here and be solid,'' Chicago first baseman Paul Konerko said. ''He doesn't have to throw shutouts. He just has to give us a chance to win. That's all we're looking for.''

Liriano has struggled somewhat this season as he is just 3-10 with a 5.31 ERA. He has walked 55 and struck out 109.

Overall the 28-year-old lefty is 50-52 with a 4.33 ERA in his career.

Liriano joins a rotation headed by All-Star left-hander Chris Sale, right-handers Jake Peavy and Phil Humber and lefty Jose Quintana, who is 4-1 with a 2.58 ERA filling in for injured John Danks.

Escobar, 23, was hitting .207 (18 for 87) with four doubles and three RBIs in 36 games for the White Sox.

Hernandez is also 23. He has split time at Double- and Triple-A this year, going 8-2 with a 2.94 ERA. He made his big league debut against Boston on July 18 and allowed eight runs in four innings.
