Jonquel Jones of the Connecticut Sun had 10 rebounds Sunday to set the WNBA single-season record at 403.
Jones eclipsed the old mark of 398, set by Tina Charles in 2010, with a rebound in the second minute of the third quarter of an 81-70 loss to the Los Angeles Sparks.
"I just wanted to come into this game and get into my groove as early as possible when it came to rebounding," Jones said. "Just being able to say that I'm able to do something like this is really special. Tina Charles did something special and to be in the same category as her it makes me feel really, really good and I'm happy to do it with my teammates."
A native of the Bahamas who is in her second season after a stellar career at George Washington, Jones began the night needing 6 rebounds to break the record.
"Pretty incredible for a second-year player to break an all-time record like that," Sun head coach Curt Miller said of the achievement. "She's one of the elite rebounders I've ever been around. She just had an unbelievable year at the defensive end, and she's just scratching the surface. Obviously she is going to just keep getting better and better at all aspects of her game, so for her to break a WNBA record in just her second year is truly remarkable and I am really happy for JJ."
Jones, in her second season in the WNBA, averaged 11.8 rebounds for the 2017 season, after averaging just 3.7 as a rookie.
The Sun finished the regular season 22-12 and have a first-round bye in the WNBA playoffs.
