>>Sox Cut Ties With Latos, Sign 1B Justin Morneau

The Chicago White Sox have designated veteran right-hander Mat Latos for assignment and signed veteran first baseman Justin Morneau.

The club immediately placed Morneau on the 15-day disabled list Thursday after he agreed to a one-year, $1 million contract with incentives.

The White Sox purchased the contract of right-hander Tyler Danish from Double-A Birmingham on Tuesday to fill Latos' roster spot.

Latos' fortunes mirrored his team's season. He was 4-0 with a 0.74 ERA after his first four starts as the White Sox raced to a 23-10 start. But Latos had a 7.25 ERA over his last seven starts as the White Sox had dropped 20 of 26 games.

Latos gave up six runs and five hits in 4 1/3 innings in a 10-5 loss to Washington on Tuesday. He is 6-2 with a 4.62 ERA in 11 starts.

Morneau is a four-time All-Star and former AL MVP, but remained unsigned after offseason surgery on his left elbow.

>>Cubs Trade For Utilityman Coghlan

The Chicago Cubs have reacquired outfielder Chris Coghlan from Oakland for Arismendy Alcantara.

Coghlan was traded to the A's in the offseason after spending two seasons in Chicago.

Coghlan, the 2009 NL Rookie of the Year, set career highs with 16 home runs and 47 extra-base hits last season. But the 30-year-old Coghlan got off to a slow start with Oakland, hitting just .146 in 51 games.

Alcantara has spent this season at Triple-A Iowa, where he hit .264 with five home runs, 21 RBIs and 21 steals.

Alcantara, 24, spent parts of the past two seasons in Chicago, where he hit just .194.
