Since the NCAA added women’s bowling in 2004, Nebraska and the University of Maryland-Eastern Shore have combined to win six of the nine national titles. Both powerhouses are back looking for more as the three-day championships open Thursday in Canton, Mich. Maryland-Eastern Shore is ranked first in the nation and Nebraska is ranked second. Leading the charge for UMES is senior Anggie Ramirez, a 2013 College Bowler of the Year finalist. She will look to lead Maryland-Eastern Shore to its third straight NCAA title, which will be awarded on Saturday. The tournament opens with qualifying rounds on Thursday before bracket play begins on Friday. The Hawks won their first NCAA championship in 2008. Central Missouri, which got the No. 1 seed in the eight-team tournament, is ranked third.
