WTA 125 tournaments

WTA 125 tournaments are an international series of professional women's tennis tournaments organized by the Women's Tennis Association since 2012.

Sometimes called the WTA Challenger tour (analogous to the men's ATP Challenger Series), it is the second highest level of women's competition, below the top-tier WTA Tour, and above the ITF Women's World Tennis Tour tournaments.

Players who succeed in the WTA 125s earn sufficient ranking points to become eligible for the main draw or qualifying draw entry of WTA Tour tournaments. Titles and losses at a WTA 125 event are separately counted from a player's WTA Tour results and corresponding head-to-head statistics.
