The Northwestern women’s lacrosse team was involved in a second straight streak-breaking game Sunday.

Once again, what snapped was a long string of Wildcat victories.

This time, Northwestern lost to Ohio State for the first time in 11 games dating to 2003.

Although the Buckeyes scored just once in the final 24 minutes, 30 seconds of regulation play, they went on to win 11-10 in overtime Sunday at Columbus in the American Lacrosse Conference opener for both teams.

Northwestern, No. 4 in last week’s rankings, had lost 9-8 to Notre Dame Wednesday.  That was the first Irish win over the Wildcats in 15 games dating to 2004.

This is the worst start to a season for the 7-time national champion Wildcats since 2002, Kelly Amonte Hiller’s first year as Northwestern head coach.  No Wildcat team since had lost more than one of its first five games.
