John Isner loses to Ryan Harrison in Sydney International second round - ESPN: "The exit of Isner, who was promoted to No. 1 seed after Jo-Wilfried Tsonga and Richard Gasquet withdrew, followed two more injury withdrawals: second-seeded and 2011 Sydney champion Gilles Simon (neck) and sixth-seeded Radek Stepanek (back).
Isner, who withdrew from the Hopman Cup mixed-team competition in Perth last week with a right knee injury, lasted 71 minutes against the 64th-ranked Harrison.
The Australian Open starts Monday, leaving injured players little time to prepare for the season's first major."
