SACRAMENTO 79, WASHINGTON 65: The Sacramento Monarchs spoiled the debut of interim coach Cathy Parsons on Sunday, beating the Washington Mystics 79-65 in a WNBA game.

The victory snapped Sacramento's six-game losing streak and sent Washington to its sixth straight loss. Sacramento (5-14) and Washington (2-16) hold the league's worst records.

The Mystics fired head coach Jim Lewis on Thursday.

Sacramento's Adia Barnes scored 15 points, followed by Ticha Penicheiro , Latasha Byears and Linda Burgess . Nikki McCray carried Washington with 27 points, two shy of her season-high.

Sacramento led nearly the entire game and gradually stretched a 37-28 halftime lead to as many as 22 points - a 66-44 edge with 7:42 remaining.

Washington made several changes under Parsons. Guard Rita Williams and forward Deborah Carter started in place of guard Adrienne Shuler and center Heidi Burge, and the Mystics deployed a seldom-used, full-court press and a more up-tempo offense.

Parson also was more animated than Lewis, standing most of the game to exhort her team.
