Four Games records fell on the second day of athletics at the Youth Olympic Games in Dakar on Monday (9), with Egypt's Yahya Sawaby and Jamaica's Marquies Page producing two of the standout performances.

Sawaby claimed the men's discus title with an African U18 record of 68.23m, moving to seventh on the world U18 all-time list and setting a world U18 lead with the 1.5kg implement.

The 17-year-old opened with 67.10m before improving to his winning mark in the third round. Jamaica's Kamari Kennedy produced a PB of 66.31m in the final round to secure silver, while Chile's Vittorio Gorziglia took bronze with 56.00m.

Page was similarly impressive in the men's 110m hurdles, clocking 12.95 (-0.4m/s) to take 0.01 off the Games record set by fellow Jamaican Jaheel Hyde at the 2014 edition in Nanjing.

The performance was also a Jamaican U18 best and moved Page to fifth on the world U18 all-time list. He finished comfortably clear of China's Shijie Chen (13.40), with South Africa's Enrique Bosch third in 13.45.

Ethiopia accounted for two of the day's other Games records, both in the distance events.

Junedin Abdo dominated the men's 2000m steeplechase, winning in 5:29.30 to finish almost seven seconds ahead of Kenya's Wesley Kiplagat Kipkech, who clocked a PB of 5:36.28. Uganda's Michael Kibet completed the podium in 5:39.50.

Abdo's performance was also a world U18 best for the event contested with 84cm barriers. His compatriot Meresa Kahsay holds the overall world U18 best of 5:19.99, achieved over the higher, standard barriers in 2013.

Ethiopia's Netsanet Selemon added another Games record in the women's 800m, winning in 2:04.43. Having clocked 2:08.28 to win her semifinal the previous day, Selemon improved on her previous lifetime best of 2:04.72 to claim the Youth Olympic title.

Nigeria's sprint success continued as Praise Ugoh added the women's 400m title to the country's two 100m gold medals from the opening day.

In one of the closest finals of the day, Ugoh clocked 52.76 to hold off Venezuela's Osmary Pacheco, who finished just 0.09 behind in 52.85. UAE's Aisha Muhammed was also in contention, taking bronze in 53.06.

Ugoh's victory was particularly impressive given that Pacheco had beaten her in their semifinal the previous day, clocking 53.01 to Ugoh's 54.38.

Kenya's Faith Rono prevailed in another close contest in the women's 3000m, winning in 9:15.47 to edge Ethiopia's Yordanos Tsigab by just 0.24. Uganda's Keren Chelimo took bronze in 9:32.41.

Elsewhere in the field events, Brazil's Pyetro Henrico Souza won the men's shot put with 19.79m, while Colombia's Ilsa Mayerlin Cordoba won the women's javelin with a PB of 57.62m.
