WNBA star Kelsey Plum and NFL tight end Darren Waller are taking a trip to Splitsville -- the two pro athletes just filed a joint petition for divorce, TMZ Sports has confirmed.
Plum and Waller got married after a year of dating in March 2023 ... and they were quite the sports power couple -- Kelsey is a two-time champion and former No. 1 overall pick, and Darren was a Pro Bowler in 2020.
It'll be a pretty clean breakup .
