National Women's Soccer League: The Washington Spirit fell to the visiting Chicago Red Stars , 2-0, on Saturday night in a game delayed over five hours because of lightning delays. Chicago improved to 3-3-6 (15 points) as Washington fell to 2-7-2 (8 points). Chicago struck first with a goal from Australian standout Sam Kerr in the 25th minute. The Red Stars earned a free kick outside the box taken by Yuki Nagasato which skipped right in front of Spirit goalie Kelsey Wys. Kerr finished the deflected ball to give the Red Stars a 1-0 lead. Early in the second half, Nagasato doubled the lead for the Red Stars. ... Spirit midfielder Rose Lavelle has been added to the training camp roster for the U.S. women's national team as the squad preps for two friendly matches against China. The game will take place on Thursday at Rio Tinto Stadium in Sandy, Utah, (9 p.m., Fox Sports 1) and June 12 at FirstEnergy Stadium in Cleveland (7 p.m.; ESPN2). Lavelle, who has worked her way back from hamstring injuries, has played in her past three NWSL matches, and after a 30-minute stint on Saturday against Chicago, was deemed fit enough to join U.S. camp.
