Hawaii senior Callee Heen hit a tie-breaking home run in the fourth inning and the Rainbow Wahine softball team opened the Hawaii Invitational with a 7-5 win over Portland State on Thursday at Rainbow Wahine Softball Stadium.

Heen went 3-for-4 and drove in three runs in support of Ashley Murphy, who gave up three runs in the top of the first but settled down to hold the Vikings to one hit over the next five innings and earned a complete-game victory.
