Vijender Singh continues to scale new heights. The Beijing Olympics bronze medallist was given top billing in the middleweight category while three Indians were also seeded for the World Boxing Championships, starting in Milan on Tuesday.

The 23-year-old Vijender, who was conferred the Khel Ratna last week, got a bye in the first round but has a tough bout in the second against a Kazakh boxer.

"Vijender was named top seed at the draw ceremony. It is amazing that Cuban boxer Emilio Correa to whom Vijender lost in the Olympic semi-finals has been seeded fifth," Indian boxing coach Gurbax Singh Sandhu said from Milan.

Among other Indians, Beijing Olympics quarter-finalist Akhil Kumar, who makes his featherweight debut in Milan, has been seeded seventh and will face Navarro Gonzalez Roberto from the Dominican Republic.

The Championships have attracted a record 553 boxers, representing 144 countries, in 11 weight categories.
