Call it rebuilding, retooling or maybe even reinvesting, but this is your White Sox offseason so far: They have lost No. 1 starter Mark Buehrle and starting left fielder Juan Pierre to free agency, and closer Sergio Santos and starting right fielder Carlos Quentin in trade.

Of course, they also lose their potential $34 million or more in salaries as the Sox try to trim a $127 million payroll.

In return, so far, they have received three inexpensive minor league pitchers with potential — big right-hander Simon Castro and lefty Pedro Hernandez from the Padres on Saturday for Quentin and Nestor Molina from the Blue Jays. Still to come is a supplemental draft choice for Buehrle.
