Jeneba Tarmoh has made the U.S. track and field team for the London Olympics, joining Allyson Felix, Tyson Gay and Justin Gatlin on the 127-athlete roster.

Tarmoh was selected as a member of the relay pool after withdrawing from a runoff Monday for the final Olympic spot in the 100 meters. She conceded her position rather than meet Felix at the starting line to break a third-place tie.

Jeremy Wariner, a 2004 Olympic gold medalist, also made the squad as part of the relay pool. Wariner didn't qualify for a spot in the 400 at U.S. track trials.

The roster announced Tuesday includes four reigning Olympic champions: Lashawn Merritt (400), Angelo Taylor (400 hurdles), Dawn Harper (100 hurdles) and Stephanie Brown-Trafton (discus). It also includes 19 American record holders.
