STOCKTON -- The Carondelet High basketball team stayed with St. Mary-Stockton most of Tuesday night, but could never take the lead in the second half as the Rams earned a 75-70 victory in an Northern California Open Division semifinal at Delta College.

Just about every time the Cougars (26-4) would get a little something going, St. Mary's (31-2) would manage to sneak in and get an offensive rebound and more often than not score off of that rebound, stifling Carondelet's attempt at a comeback.

"They scored off of almost every offensive rebound," Cougars coach Margaret Gartner said. "They had 14 and scored on almost every put-back."

Carondelet shot often from behind the arc but only had three 3-pointers.

"We kind of count on those 3-pointers," Gartner said. "When we miss those, that makes it a little bit tighter and then every rebound counts and when we don't get those, that kind of opens up the game."

The Cougars had four players in double figures, as Natalie Romeo had 15 points, Amy Harioka had 14 and Lauren Nicolosi and Marcella Hughes each finished with 10. Nicolosi talled a double-double as she had 10 rebounds and Romeo added two assists and two steals.

"This was a really great year," Romeo said. "We had the best team chemistry of any team I have played on but in this game we just couldn't make our outside shots."

Charise Holloway of the Rams led all scorers with 19 points.

St. Mary's will play in the NorCal finals on Saturday at Sleep Train Arena in Sacramento at 6 p.m. against Bishop O'Dowd.
