"I learned from previous experience that a fastball was not going to work well in the rain," Cupp said. "The spins don't work well in the rain either."

Cupp, who throws a fastball, riseball, screwball, curve and changeup, used more changeups versus the Eagles.

Beckman (10-3) also pitched a complete game, allowing three runs. She threw mostly drop-curves against Harvard.

"I tried to keep it low and outside," Beckman said. "I also tried to keep the ball dry, which is difficult to do in the rain."

On Saturday, Harvard hosts Princeton at Soldier's Field.

"Princeton is always ready to go," Kreuder said. "They have good hitters and are tough defensively." B.C.  4 Harvard  6
