PHOENIX — Now they were just showing off, treating the crowd to an encore. Jackie Young zigged and zagged to the rim. Chelsea Gray’s strange-looking heaves swished in. NaLyssa Smith pulled down all the right boards. Jewell Loyd popped into open threes from screens. The universe can sometimes be indelicate with its symbolism: A’ja Wilson slid across the paint to block DeWanna Bonner. The ball spun in the air and fell on Bonner’s head. Through it all, the Las Vegas Aces led, and led, and led, and led.
With a 97-86 Game 4 win over the Mercury in Phoenix on Friday night, the Aces won their third WNBA championship in four years to finish a Finals sweep and an unthinkable in-season turnaround. After beginning the regular season 14-14, they finished it on a 16-game win streak. Including the postseason, they won 25 of their last 28 games.
