Markgraf earned the cap in style as she wore the captain's armband, becoming the seventh player to reach 200 career caps for the U.S.
Red Stars midfielder Megan Rapinoe also started for the U.S. and forward Kosovare Asllani got the start for Sweden. The U.S. and Sweden square off again Saturday in Hartford, Conn.
Markgraf, 33, a Notre Dame alumna, missed the 2009 Women's Professional Soccer season and did not play for the national team last year because she gave birth to twins. Markgraf made her return to the U.S. squad in late May for her 199th cap as the Americans defeated Germany, 4-0, in Cleveland.
