Stefanchik bunted her way on with one out and Gordon followed with a single to left to give Harvard runners at first and second.

That set the table for Fritsch, who walloped a shot over the left field fence for her third home run of the season and three more RBI.

Bettinelli kept the inning going with a single to center, advancing to second on a sacrifice bunt from Halpenny. Williamson knocked in Bettinelli with a double down the left field line and gave the Crimson a 4-0 lead.

Brotemarkle then did what comes natural to her, setting Bulldog batters down time after time, aided by the pitch calling of Halpenny.

“Our offense really came through and got us a good cushion, so we could relax a little on the field,” Brotemarkle said.

Harvard added two more insurance runs, superfluous with Brotemarkle on the mound, in the sixth and seventh innings.

Stefanchik and Fritsch both went 3-for-4, and Williamson and Gordon batted 2-for-4 on the day.

The Crimson face cross-town rival Boston College on Thursday at Chesnut Hill, and then will play host to Dartmouth on Saturday for its final Ivy doubleheader.
