Las Vegas closed out the winner-take-all Game 3 with a 94-83 home victory, eliminating Indiana and reaching the WNBA semifinals for the second straight year over the Fever.
A'ja Wilson powered the Aces with 36 points and 10 rebounds, while Caitlin Clark was held to 18 points on 6-of-18 shooting as Las Vegas regained control after splitting the first two games.
Chelsea Gray also helped steady the reigning champions, who answered Indiana's Game 2 comeback and kept their repeat title bid alive on their home floor.
The Aces now move on to face the winner of the Valkyries-Wings series, while the loss ends the Fever's push to turn a high-scoring regular season into a deeper playoff run.
