Boris Becker's 1989 US Open men's singles trophy -- the only known US Open men's singles trophy from the Open era to hit public auction -- sold for $357,546 (including buyer's premium) with The Tennis Auction on Sunday, the most ever paid for a tennis trophy.
It's the second-most expensive item of tennis memorabilia ever sold behind Novak Djokovic's 2012 Australian Open-winning racket, which went for $540,000 in February.
