Senior Dan Zailskas, shown here in earlier action, helped the Crimson to a sweep of first-place Dartmouth on Saturday at O’Donnell Field. Zailskas made the most of Senior Day, going 2-for-2 with a walk and a pair of runs scored in the first contest before plating a run and scoring one of his own in a 2-for-5 performance in the nightcap. Zailskas also completed a solid day in the field for Harvard, diving to snag a line drive during the second contest to prevent a hit.
