## Statistical information

These tables present the number of singles (S), doubles (D), and mixed doubles (X) titles won by each player and each nation during the season, within all the tournament categories of the 2018 WTA Tour: the Grand Slam tournaments, the year-end championships (the WTA Tour Championships and the WTA Elite Trophy), the WTA Premier tournaments (Premier Mandatory, Premier 5, and regular Premier), and the WTA International tournaments. The players/nations are sorted by:
* total number of titles (a doubles title won by two players representing the same nation counts as only one win for the nation);
* cumulated importance of those titles (one Grand Slam win equalling two Premier Mandatory/Premier 5 wins, one year-end championships win equalling one-and-a-half Premier Mandatory/Premier 5 win, one Premier Mandatory/Premier 5 win equalling two Premier wins, one Premier win equalling two International wins);
* a singles > doubles > mixed doubles hierarchy;
* alphabetical order (by family names for players).

* Rebecca Marino (born 16 December 1990 in Toronto, Canada) joined the professional tour in 2008 and reached a career-high ranking of no. 38 in singles. She reached her first and only tour-level final at the 2011 U.S. National Indoor Tennis Championships, losing to Magdaléna Rybáriková. She took a break from tennis to deal with mental and physical fatigue from February to August 2012. After playing some ITF and WTA tournaments, she decided in late February 2013 to take a second break from tennis with no timetable for her return. Marino started training again during the first week of September 2017 and decided to return to competition in October 2017, after being away from the game for nearly five years. She was scheduled to play an ITF 60K event in Saguenay but her comeback was delayed of three months due to ITF administrative regulations. She returned at an ITF 15K event in Antalya at the end of January 2018 and won the title in her first tournament back.
