CHULA VISTA, California--Competing in one of the low-key meets at the Olympic Training Center, University of Washington alum Brad Walker (left/photo courtesy USA Track & Field) tied for first with Great Britain's Steve Lewis at the OTC Pre-World 7 meet.

Walker, the two time US Olympian and 2007 world outdoor pole vault champion, and Lewis each jumped 18-0 1/2 (5.50m), clearing on their second attempt, before missing three attempts at 18-8 1/2 (5.70m).

The Husky alum is the current world leader in the pole vault, as he cleared 19-1 1/2 (5.83m) last Friday in Phoenix.

Club Northwest's Levi Keller no-heighted, failing to clear his opening height of 17-0 3/4 (5.20m).

Walker is scheduled to jump at next week's Nike Prefontaine Classic stop of the IAAF Diamond League tour in Eugene's Hayward Field.
