MELBOURNE — Frustrated Australia number one Bernard Tomic questioned team mate Nick Kyrgios's withdrawal from the Davis Cup tie against the United States in Melbourne after the hosts crashed out of the tournament's first round on Sunday.
Rising talent Kyrgios withdrew from the tie with a virus days before the opening singles on Friday, leaving 77th-ranked Sam Groth to battle world number 11 John Isner at Kooyong Lawn Tennis Club.
Groth was beaten easily by Isner and the big-serving American returned on Sunday to grind down 20th-ranked Tomic in four sets and put the U.S. into the quarter-finals for the first time in three years.
