Unseeded Harvard players, freshman Alexandra Lehman and Rosekrans, fell in the first and second round, respectively.

Tachibana, who has been undefeated in singles this preseason and has won multiple tournaments, finally met her match this weekend. The three-seed cruised past her first two opponents, but fell emphatically to Magdalena Ploch of UMass, 6-2, 6-2.

“It was just bound to happen,” Green said on Tachibana’s first loss. “She’s had an excellent fall so far. She had a really good doubles weekend as well.”

The indoor regional tournament is one of the more important competitions of the fall season. According to Green, the success of her young players was impressive.

“I thought the overall results were very solid,” Green said. “Our team being so young, we really showed a lot of promise this weekend.”

Cao takes the court today at 10:30 a.m. for her semifinal match, and then will play in the finals this afternoon pending the result of her first match.

“I’m going into the match focusing on my game and trying to do my best,” Cao said. “I’m hoping to win tomorrow, obviously. A more important thing though is to improve with each match. That’s the main goal.”
