Nick Kyrgios of Australia paid tribute to Kobe Bryant in his fourth-round match at the Australian Open on Monday by wearing a Lakers No. 8 Bryant jersey before he was to play Rafael Nadal of Spain. In addition to mourning the NBA great, who died with his daughter and seven others in a helicopter crash Sunday, perhaps Kyrgios was hoping to channel the competitive grit of the former Lakers star. Kyrgios and the top-seeded Nadal are bitter rivals, with Nadal having won four of their seven previous encounters.
