Among all players who attempted three or more attacks, sophomore middle blocker Riley Moore posted the highest kill rate at 80 percent while Dow was not far behind at 67. All afternoon the duo hit over a Sacred Heart defense that recorded as many blocks (two) as blocking errors.

The Pioneers’ offense largely came from the trio of Michael Comens, Chris Delucie, and Austin Arcala. All three players racked up nine or more kills, and Comens topped his squad with 13 finishes.

In the first set, the Crimson battled back from an early two-point deficit to tie the game at seven. The teams traded points until later in the set, when Harvard held a 19-18 lead. Then, partly thanks to four errors by Sacred Heart, the hosts turned on the jets, winning six of the last seven points for a 25-19 victory.

The Crimson limited the Pioneers to a 6 percent kill rate in the frame, an early indication of defensive dominance. For the fifth straight contest, Harvard ended with double-digit blocks as a team, led by five by Moore.

The victory positions the Crimson a full game ahead of St. Francis in the conference, roughly half of EIVA competition remains to be played.

“We want to be winning our conference,” Clemens said. “Ideally we want to win out.”
