Caitlin Clark scored a career-high 35 points with eight assists, Kelsey Mitchell added 30 points and the duo combined to hit 12 of Indiana's 16 3-pointers to help the Fever beat the Dallas Wings 110-109 on Sunday.

Clark, whose 329 assists are a single-season WNBA record, has a rookie-record 761 points this season, breaking the mark set by Seimone Augustus (744) in 2006.

Indiana (20-19), which was coming off back-to-back losses to the two-time defending WNBA champion Las Vegas Aces, clinched the No. 6 seed in the playoffs, which begin next Sunday. The Fever will play the third-seeded Connecticut Sun, who won three of the four regular-season matchups between the teams, in the first round.

Indiana tied its franchise record for single-game scoring and tied its season high for made 3s. The Fever made 38 of 76 from the field, shot 47 from the free-throw line.

Clark made a driving layup, stole a pass on the other end and then came off a screen by Temi Fagbenle and made another layup to give the Fever a 90-86 lead with 6:35 to play. Teaira McCowan scored inside to cut the deficit to two, but Clark made back-to-back 3s and, after a transition take foul, hit a free throw to make it 97-88 with four minutes left.

Arike Ogunbowale made a contested runner in the lane and then a layup to spark an 8-0 spurt that pulled the Wings within a point with 2:27 remaining. Mitchell hit a 3-pointer off an inbounds pass from Clark and, after Satou Sabally scored in the paint, Damiris Dantas hit 3s 25 seconds apart to give Indiana a 106-98 lead with a minute to go.
