USWNT held scoreless by Costa Rica in last Olympic warmup

The United States women's soccer team played to a 0-0 draw with Costa Rica in sweltering temperatures Tuesday night in its final exhibition tuneup before the Paris Olympics.

It was 98 degrees Fahrenheit (37 Celsius) at kickoff in Washington, D.C. Tuesday's temperatures tied the hottest day on record in the nation's capital at 104 (40C) hours earlier.

Coach Emma Hayes figured it would be a nice test for her players, given the forecast for nearly this level of heat during upcoming games in Marseille later this month.

"That's added value," Hayes said Monday. "It's perfect preparation. It's pretty hot down there, so this is a great opportunity for us to experience what we're going to face."

It played a role in Rose Lavelle being a late scratch because of leg tightness in warmups, with team staff deciding it was not worth the risk given the circumstances. A team spokesperson said Lavelle was fine.

Korbin Albert replaced Lavelle in the starting lineup for the game at Audi Field, taking place on a worn-down playing surface torn up by recent football, soccer and rugby matches and attended by 18,972 fans.

The U.S. generated plenty of chances throughout and was repeatedly denied by Costa Rica goaltender Noelia Bermúdez, who at one point in the first half collided with Trinity Rodman. Each player went down and received medical attention but remained on the field.

Costa Rica, which did not qualify for the Olympics, sat back often and had no shots on goal with just two attempts, while the U.S. was consistently on the attack.

After a ceremony following the Americans' "Send-Off Match," they are set to fly to Paris on Wednesday and play their Olympic opener July 25 against Zambia in Nice. Games in Marseille against Germany on July 28 and against Australia on July 31 wrap up group play as the Americans look to improve on their bronze-medal result in Tokyo three years ago.

Hayes, who has been coaching the U.S. only since late May, was proud of the possession domination in a 1-0 victory Sunday against Mexico in New Jersey, but said Monday it was about "doing more with it." Much of the same followed Tuesday versus Costa Rica, including a couple of would-be goals called off for offside and a few missed opportunities on corners and off the rush.

With a mostly young, inexperienced roster, Hayes also wanted to get as many players into the game as possible. She made four substitutions at the 67-minute mark and one other late to help those efforts.
