The surprising Chicago White Sox have made a move to stay on top of the AL Central, acquiring left-hander Francisco Liriano from division rival Minnesota Twins on Saturday night.

The Twins will receive infielder Eduardo Escobar and left-handed prospect Pedro Hernandez.

An All-Star in 2006, Liriano was expected to be one of the Twins’ top starters before undergoing reconstructive elbow surgery that same year. His career has since been plagued by inconsistency and injury.

He pitched a no-hitter in May 2011 against the White Sox but was 9-10 with a 5.09 ERA for the year.

This year Liriano struggled at the start and was demoted to the bullpen after his ERA rose to 9.45 in early May. He has brought that down to 5.31 in 11 starts since his return to the rotation but still is 3-10 this season.

The 28-year-old is 50-52 with a 4.33 ERA in his career.

Street, Padres agree to deal

All-Star closer Huston Street and the San Diego Padres have agreed to a $14 million two-year contract through 2014.

The deal announced Sunday includes $7 million salaries for each of the next two seasons and a $7 million team option for 2015.

Street is making $7.5 million this year in the final guaranteed season of a $22 million three-year contract he agreed to with Colorado in January 2010. He could have exercised a $9 million option for 2013.

Street, who turns 29 Thursday, is 2-0 with a 0.91 ERA and has converted all 17 save opportunities in his first season with the Padres.
