Sha'Carri Richardson and Christian Coleman gun for confidence-boosting records at Prefontaine Classic

Track couple Sha'Carri Richardson and Christian Coleman will gun to etch their names in the history books when they line up in their respective events at the Prefontaine Classic Diamond League in Eugene on July 5.

The romantic pair who are part of the headliners for the 50th anniversary of the Prefontaine Classic will compete in the main 100m events, in which victories for them will put their names among the greats in the meet's history.

Richardson is confirmed to run in arguably the deepest 100m field in Diamond League history, facing familiar rivals: Olympic champion Julien Alfred and bronze medallist Melissa Jefferson-Wooden, who both have the top two fastest times in the world this year.

Also in the stacked lineup are the Jamaican duo of Tina and Tia Clayton, both in the best career shape of their lives, as well as in-form sprint sensation Favour Ofili.

A win for Richardson will see her become the first American woman to win back-to-back Pre Classic 100m titles since Torri Edwards (2006-2008).

Meanwhile, Coleman will be aiming to become the second man to three-peat in the Pre Classic 100m, after Justin Gatlin (2012-2014).

The former world champion is having a torrid season with failed attempts at winning any of his races this season or going under the sub-10s mark.

This time in Eugene, Coleman will face a strong field spotlighted by world leader Kishane Thompson, back-to-form American rival Trayvon Bromell, and South African rising star Bayanda Walaza.

Victories for Richardson and Coleman will greatly build their confidence for the rest of the season, especially ahead of the US Championships this month and the World Championships in Tokyo in September.
