MELBOURNE (Reuters) - Two weeks after declaring he lacked any dedication to tennis, Nick Kyrgios has pledged to fire up for Australia's bid to reach the Davis Cup final.
Australia play Belgium in the semi-final in Brussels this weekend, looking to secure their first trip to the decider since their 2003 win over Spain.
