Doran's sustained strong play has elevated him into the top 100 in the nation, and he now holds the No. 93 spot.
Freshman William Lee provided another impressive win at the No. 6 slot, mimicking the quick work of his teammates at the top of the line-up with a 6-2, 6-2 triumph.
Lee has been solid in the bottom half of the Crimson juggernaut for most of the Ivy League season. Against Brown and Yale, Lee dispensed of his opposition in straight sets, including a league-clinching win against Yale while playing up at the No. 5 position.
At the No. 3 and 5 positions, Harvard took a little more time but ended up on top. Playing at No. 3, Green jumped out to an early lead but dropped the second set in 12 games. With the score leveled at a set apiece, Green had had enough. The Irishman stormed past his opponent in the third to win, 6-4, 5-7, 6-1.
Passarella went about his win with a different approach. After capturing the first set, 6-1, the fiery senior dropped the second, 7-5, and battled through the third to triumph in a tiebreaker and complete the sweep.
The Crimson now has two weeks off before it travels to the NCAA regional championships at a sight to be announced in the next couple of weeks.
