David Oliver keeps lowering his personal-best in the 110-meter hurdles, rapidly closing in on the world record set by Cuba's Dayron Robles two years ago.

Oliver shaved .01 seconds (12.89) off his American record at a Diamond League meet in Paris on Friday. He is USA TODAY's Olympic athlete of the week.

The 28-year-old who lives in Kissimmee, Fla., equaled the American record two weeks ago at the Prefontaine meet when he ran 12.90. His time at the Paris meet makes him the third-fastest man all-time behind Robles and Liu Xiang.

Robles' world record is 12.87 set in the runup to the 2008 Beijing Olympics, where he won gold. He has not broken 13 seconds so far this season and did not run in Paris.

Oliver, this year's U.S outdoor champ, leads the Diamond League standings with victories in Shanghai, Eugene, Ore. and Paris.

There are three Diamond League races left in the 110 hurdles.
