NBA HORSE Challenge: LaVine sweep, CP3 loss highlight quarterfinal results

The eight-person, single-elimination NBA HORSE Challenge kicked off on Sunday with four quarterfinal matchups between NBA and WNBA stars past and present.

Here's how the action from the tournament's opening night went down:

Matchup 1: Chauncey Billups def. Trae Young

With Billups down H-O-R to nothing, the former Detroit Pistons great wound up rallying to eliminate Young, showcasing why he earned the nickname "Mr. Big Shot" during his NBA career.

The Atlanta Hawks star entered the event with extremely high expectations, but he wasn't able to overcome Billups' late push.

Billups became the first participant to book a spot in the semifinals, and Young is already eager to organize a rematch.

Matchup 2: Mike Conley def. Tamika Catchings

Conley cruised to a decisive victory over Catchings after getting out to a quick four-letter advantage against the WNBA Hall of Famer.

The Utah Jazz point guard made use of his off-hand often, including on an impressive right-handed layup over top of the backboard from behind the baseline.

Conley was only handed an H in the win.

Matchup 3: Zach LaVine def. Paul Pierce

LaVine made sure to take advantage of his athleticism against the 42-year-old Pierce en route to sweeping the 2008 Finals MVP.

The Chicago Bulls star showed off his range for the game-clinching bucket, draining a long jumper from a dirt patch next to his court.

Matchup 4: Allie Quigley def. Chris Paul

Undoubtedly the most competitive matchup of the quarterfinals, Quigley surged to a two-shot lead over Paul to open the game, and she didn't slow down from there.

The Chicago Sky sharpshooter even managed to channel her inner Pistol "Pete" Maravich by converting a shot off the backboard while sitting down.

Paul made up some ground to nearly pull off a comeback after trailing H-O-R-S to H. But he wasn't able to complete the job in the last quarterfinal matchup of the tournament, setting up an all-Chicago semifinal between Quigley and LaVine.

What's next?

The semifinals and final will be broadcast Thursday, April 16 at 9 p.m. ET on ESPN.
