Dale Silha on Demerath: "I expect great things from Marie this year. After spending most of the previous year with a shoulder injury, she is healthy once again. As our team captain, Marie has really helped bring this team together."
2008-09: Demerath added three more singles wins in 2008-09, bringing her career singles win total to 27.
