James Harden's 42 points in the Sixers' OT win, Lonnie Walker IV willing the Lakers to a fourth quarter comeback, and more - we revisit the top performances from the recent Game 4s.
In the Eastern Conference, the Miami Heat are just one win away from a place in the conference finals as they hold a 3-1 lead over New York Knicks, while the other semifinal between the Philadelphia 76ers and Boston Celtics is tied at 2-2 ahead of Game 5 on Tuesday.
The defending champion Golden State Warriors trail the Los Angeles Lakers 3-1 in the Western Conference semis, while the top-seeded Denver Nuggets lost both games in Phoenix and are tied with the Suns two games apiece.
We’ve had a look at some of the standout performers from all the Game 4s of the NBA Playoffs.
James Harden put in a season-saving display as the 76ers fought back to level things up with the Boston Celtics at the Wells Fargo Center on Sunday night.
Harden won the MVP award in 2018, is a three-time scoring champion, two-time assist leader and 10-time All-Star - but he has yet to claim an NBA Championship.
That could all change this year with the Sixers and he led the way for his team on Sunday as Philly claimed a win in overtime.
The 33-year-old finished the night with 42 points, eight rebounds, nine assists, four steals, one block - but, stats aside, he came through for the team when it really counted.
Philly held a nine-point advantage going into the fourth quarter but Boston hit back to take the lead, with Harden then hitting a floater with just 16 seconds of regulation time remaining to send the game into overtime.
Harden was the Sixers’ clutch hero again in overtime, sinking a game-winning three-pointer to cap off a truly remarkable performance as he became just the fourth player in league history to put up at least 10 40-point playoff games, joining Jerry West, Michael Jordan and Kobe Bryant.
The Warriors had to fight back from a two-game deficit in their first round win over the Sacramento Kings, and they'll need to repeat that feat if they are to defend the championship after falling 3-1 behind against the Los Angeles Lakers.
The Lakers appeared in danger of missing the playoffs altogether as the regular season drew to a close but they are now just one win away from the Conference Finals - and they have Lonnie Walker to thank after they overcame the Dubs 104-101 on Monday.
Walker began the season as a starter but injury and then a trade deadline transformation saw him slip down the rotation.
The 24-year-old came off the bench and delivered in Game Four, scoring all 15 of his points in the fourth quarter, outsourcing Stephen Curry in that period, as the Lakers fought back from a 12-point deficit in the third quarter to claim a win.
"(It’s) the greatest feeling you could ever imagine," Walker said after the game, as reported by ESPN.
"As a kid, this is something I've been dreaming of."
Devin Booker has been one of the standout players in the playoffs so far and he came up with another sublime performance in Game Four of Phoenix Suns’ series with Denver.
The guard is averaging 36.8 points-per-game across the playoffs this year and in Game Four he finished with 36 - on 14-for-18 shooting as he missed just one of his three-point attempts.
Booker also had 12 assists and six rebounds, and his display perhaps kept Phoenix in the series as the Suns managed to survive a huge night from Nikola Jokic.
The two-time MVP had a playoff career-high 53 points but his efforts proved to be in vain as the Suns levelled up the series ahead of Game Five in Denver on Tuesday.
