WASHINGTON (Reuters) - Sprint Corp's <S.N> newly appointed Chief Executive Marcelo Claure has so far had a Midas touch in the telecoms industry, turning Brightstar, a reseller of U.S. handsets to Latin America, into a distributor valued at $2.2 billion when it was sold to Japan's SoftBank <9984.T>.
But his talents will now be put to the test like never before as he must complete the No. 3 carrier's network upgrade while trying to retain customers, who are defecting in droves.

The move is a rare setback for Sprint's Japanese parent, SoftBank Corp 9984.T, whose billionaire founder Masayoshi Son had seen the acquisition as key to taking on U.S. market leaders AT&T Inc T.N and Verizon Communications Inc VZ.N.
