Wal-Mart Stores says it is promoting Bill Simon to president/CEO of Walmart U.S., and shifting Eduardo Castro-Wright, who has held the post for five years, to the West Coast, where he will be president/CEO of its Global.com and Global Sourcing.

Both will report directly to Mike Duke, Walmart's president/CEO.

The Wall Street Journal reports the move comes several weeks after Castro-Wright's wife underwent a heart transplant in California. While the Bentonville, Ark.-based retailing giant posted quarterly profits above expectations last month, same-store sales in the U.S. actually declined 1.4%, while sales at rival Target increased.
