The Washington Spirit made its National Women’s Soccer League debut Sunday evening with a 1-1 draw against the Boston Breakers in Somerville, Mass.

Tiffany McCarty, The Post’s All-Met player of the year in fall 2007 at St. John’s High School, scored on a six-yard header in the 15th minute.

But U.S. national team forward Sydney Leroux scored the equalizer in second-half stoppage time, beating goalkeeper Ashlyn Harris with a 10-yard shot to the far corner.

The Spirit had several other quality scoring opportunities in the game, but Breakers goalkeeper Ashley Phillips tipped Diana Matheson‘s 30-yard bid off the crossbar and blocked Stephanie Ochs‘s point-blank shot.

A few minutes before Boston’s goal, Harris was injured in a collision with Leroux but, after being treated for several minutes, remained in the match.

The Spirit will play its home opener Saturday night against U.S. superstar Abby Wambach and the Western New York Flash. Kickoff is at 7 p.m. at Maryland SoccerPlex.
