SCOTTSDALE, Ariz. --Second-seeded Kim Clijsters beat Meghan Shaughnessy 6-3, 7-5 Saturday at the State Farm Women's Tennis Classic to reach her third final of the year.

Clijsters will play either Alexandra Stevenson or Ai Sugiyama in Sunday's final (ESPN2, 4 p.m. ET). Their semifinals match was rained out Saturday and was rescheduled for four hours before Sunday's final at 1 p.m. ET.

Because rain forced delays throughout the tournament, Clijsters had to play two singles and a doubles match Friday. She said she was concerned about her energy level Saturday.

"I started to feel it a little bit toward the end,'' Clijsters said. "That's why I tried to finish it off in two sets. I'm still young, so I hope I can manage a three-set match.''

Clijsters won at Sydney this year and lost to Venus Williams in the final at Antwerp. She has a 15-2 match record this year, with the only other defeat to Serena Williams in the Australian Open semifinals.
