The Chicago White Sox have begun receiving trade calls about outfielders Alejandro De Aza and Dayan Viciedo.

The pair are battling for the everyday job in left field.

Adam Eaton and Avisail Garcia appear to have the jobs in center and right field nailed down.

De Aza, 30, is the more established player of the two, but also comes with less team control.

He has batted .279/.343/.420 in 357 games with the White Sox since being claimed off waivers from the Miami Marlins in 2009.

Viciedo, who turns 25 on Monday, hit 25 homers in his first full season with the Sox in 2012, posting a .255/.300/.444 triple-slash line.
