On defense, Yick dug 17 balls and senior outside hitter Anne Schafer added 13 digs.
It was Schafer, Forcum said, who stepped in to fill the void left by the three missing players, contributing nine kills and an ace.
"Anne came in and played really well," Forcum said. "She had a good hitting game."
Despite the loss of the starters, Harvard has played well as a team, Yick said.
"We've stressed all season long that we are a team of 14," she said. "Once we do get our starters back, we'll be that much stronger."
Harvard puts its unbeaten Ivy record this weekend at home against Princeton (8-9, 2-1 Ivy) and Pennsylvania (5-8, 0-3 Ivy).
"We don't really need any fire up stuff," Forcum said. "Especially for Princeton. Brown beat them, and that gives us a little bit of confidence. We've seen Brown play already this year."
With that confidence, and the home floor, Harvard hopes to stay atop the Ivy standings and break the tie for the lead with Dartmouth and Brown.
