Your 2016 Citi Open primer, one number at a time. Main draw matches on the hard courts at the FitzGerald Tennis Center in Rock Creek Park begin Monday with the championships for the men's (ATP) and women's (WTA) tours set for July 24.
1 - As in top seeds John Isner and Samantha Stosur in the ATP and WTA draws respectively. Isner, the top ranked American on tour, is a perennial contender in Washington, but is still looking for his first title. The big server fell to 0-3 in D.C. finals with last year's three-set loss to Kei Nishikori. Stosur, the 2011 U.S. Open champion, aims for her first title in 2016. The Aussie reached the semifinals in her Citi Open debut last year.
3 - As in the number of Citi Open titles won by Juan Martin del Potro. Alas, the Argentine won't be adding a fourth as Del Potro withdrew Saturday due to a lingering wrist injury. Eighth ranked Tomas Berdych also bowed out in recent days, leaving Isner, Gael Monfils and Bernard Tomic as the remaining top 20 players on the men's side.
4 - As in the number of Washington titles won by returning champions. Sloane Stephens won the first of her four career tour titles last year on the Rock Creek hard courts with a 6-1, 6-2 thrashing over Anastasia Pavlyuchenkova. Alexandr Dolgopolov won the men's championship in 2012, the same year Magdaléna Rybáriková won the first of her back-to-back titles.
7 - As in the number of Monfils victories in Washington, including four in 2011 when he reached the finals. That was also the last year the dazzling Frenchman played locally.
8 - As in the seed for Sam Querrey, the hard-hitting American who pulled off the shocker of 2016 by downing Grand Slam chasing Novak Djokovic in the round of 32 at Wimbledon. Querrey, a hard court champion (Delray Beach) this year, hasn't won more than one match in a single Washington tournament since reaching the semifinals in 2012. Truth is, none of that matters much after watching this. Amazing.
14 – As in the number of times a player, whose first name started with the letter “A” won the men's championship in 35 years. Random factoid for sure, helped in the past by multiple time winners Andre Agassi and Andy Roddick and most recently Dolgopolov.
14 - As in the number of days earlier the 2016 Citi Open starts compared to the 2015 version. The reason? The upcoming Summer Olympics in Rio. Typically Washington serves as a hard court tuneup for the year's final major, the U.S. Open.
23 - As in the number of career titles for former world No. 1 Caroline Wozniacki, who makes her Citi Open debut this year. Though the Denmark native has spent time in the area in part because of a past relationship with Washington Redskins linebacker Ryan Kerrigan, getting used to the heat -- and humidity -- takes a minute.
500 - As in this being an ATP World Tour 500 Tournament, making the Citi Open of the top 20 men's tournaments in the world.
1970 - As in the year of the first D.C. Tournament. Agassi leads with five singles titles.
