“US Open March Moments” is a bracket-style tournament to determine tennis fans’ favorite moment in the US Open’s rich history, with the winner determined by voting on Twitter. Along with our fan vote, we are also offering a sweepstakes for two tickets to Opening Night of the 2019 US Open. Before entering, please read the official rules.

As March comes to a close, we are closing in on the ultimate US Open moment. Our fan-vote tournament has reached the quarterfinal stage, with the final three rounds set to play out this week.

As in Round 1, Roger Federer's fifth consecutive US Open title (2008) scored the most comfortable victory, this time earning 72 percent of the vote against Martina Navratilova's 1987 triple crown. 

The eight remaining moments span throughout the past 50-plus years, from Arthur Ashe's title at the inaugural US Open in 1968 to Rafael Nadal completing his career Grand Slam at the 2010 event. The 1990s provide three of our quarterfinal moments—the most of any decade—courtesy of Jimmy Connors, Andre Agassi and Serena Williams, who won her first New York title nearly 20 years ago, in 1999.

Agassi, whose 2006 farewell topped wife Steffi Graf's 1988 Grand Slam, is responsible for two of the eight final moments as the only repeat quarterfinalist.

Stay tuned to USOpen.org for the final March Moments results, with the winner set to be crowned on Friday. Quarterfinal, semifinal and final voting will take place over the course of the week.

To participate and vote for your favorite moments, follow the US Open on Twitter. Complete Round 2 voting results are below, with links to full stories on each individual moment. Round 1 results and story links are available in our opening-round recap story.
