LOS ANGELES — There are nonetheless milestones left for LeBron James to achieve, as inconceivable as that appears.

In a 20-year profession during which James has powered three franchises to championships and develop into the N.B.A.’s profession scoring chief, he had by no means grabbed 20 rebounds in a recreation. Not within the common season. Not within the postseason.

Not till Monday. Till his Los Angeles Lakers wanted his muscle, his expertise and his instinct. Till they wanted James to push a brash younger opponent, the Memphis Grizzlies, to the brink of a first-round playoff elimination.

“These are the moments that I really like,” James stated. “I really like the postseason.”

The 117-111 additional time victory James helped ship on Monday night time led the Lakers, who began the season 2-10 and appeared misplaced heading into the commerce deadline, to a 3-1 collection lead over the Grizzlies, who spent all season as the most effective groups within the Western Convention.

The Lakers are on this commanding place as a result of James discovered a solution to push by means of his exhaustion within the remaining minutes of Sport 4 and add to his lore. He grabbed rebounds, he took prices, he made a driving layup by means of contact with 29.1 seconds left in additional time and screamed into the gang as he pounded on his chest.

“He understands the timing, the timing of every little thing,” Lakers Coach Darvin Ham stated. “The identified of what occurred yesterday and the unknown of tomorrow, it makes him much more entrenched in immediately, into the second.

“All of his travels. All the phenomenal issues he’s achieved — he nonetheless has that zeal, that grit to wish to be on prime and to wish to put his workforce in place, the suitable manner, to achieve success. That’s what you noticed.”

With 22 factors and 20 rebounds, James turned the primary Laker to achieve 20 factors and 20 rebounds in a playoff recreation since Shaquille O’Neal in 2004. At 38, he turned the oldest participant in N.B.A. historical past to have 20 factors and 20 rebounds in a recreation, beating a playoff mark set by Wilt Chamberlain in 1973.

James’s presence is a part of the explanation it has been clear from the beginning of this collection that the Lakers are not any strange seventh seed. Their file didn’t replicate who they had been as soon as Anthony Davis and James had been accessible, if not totally wholesome. Additionally they improved considerably after remaking their roster on the commerce deadline.

Conversely, the Grizzlies got here into the postseason hobbled. Their beginning middle, Steven Adams, has been out with a knee harm, and Brandon Clarke, one other participant who lent dimension to their lineup, has additionally been injured.

Memphis misplaced Sport 1 at residence. However, well-known for his or her bluster, that early defeat didn’t humble them. One Grizzlies participant, Dillon Brooks, went straight at James on the court docket and off it.

Throughout Sport 2, Brooks stated James known as him “dumb” for buying his fourth foul.

“I don’t care — he’s previous, you understand what I imply?” Brooks responded.

“I used to be ready for that,” he continued. “I used to be anticipating him to do this Sport 4, Sport 5. He wished to say one thing after I bought my fourth foul. He ought to have been saying that earlier on. However I poke bears. I don’t respect nobody till they arrive and provides me 40.”

Making a rivalry with James may be a straightforward manner for an additional participant to siphon a few of his highlight. James knew that and wished no a part of it.

After a apply final week, James was requested a number of questions on Brooks’s feedback and sidestepped every one. He then ended his information convention early, earlier than he was tempted to say something which may escalate the feud. He stated he most popular to talk by means of his play.

Within the minutes earlier than Sport 3, although, James approached Brooks. There was no audio, however cameras caught the interplay and the video circulated on social media.

“There was nothing non-public about it,” James stated after the sport, freely giving that he wasn’t really ignoring all that Brooks had stated. “It was very, very public. I prefer it that manner.”

The Lakers led by 35-9 after the primary quarter of that recreation, driving their followers right into a delirious frenzy and making Memphis’s bravado appear silly. The Grizzlies by no means recovered from their poor begin regardless that Ja Morant scored 45 factors. Brooks was ejected within the third quarter for a flagrant foul assessed when he struck James within the groin, placing an early finish to no matter battle may need been brewing between them.

Nonetheless, not every little thing got here simply for the Lakers on Monday.

They’d a 15-point lead within the second quarter, however Memphis closed the primary half with a 14-1 run and the Lakers led by simply 2 at halftime. To finish the third quarter, Morant wove by means of the paint to dunk the ball as time expired and gave Memphis a 2-point lead.

Late within the recreation, nonetheless, the Lakers bought vital contributions from a number of gamers. Davis, after a quiet recreation by means of three quarters, made vital defensive performs late. D’Angelo Russell made three 3-pointers inside a one-minute span through the fourth quarter to tug the Lakers out of a 7-point deficit.

However James’s contributions, as he fought by means of fatigue within the closing minutes, meant essentially the most.

“You simply dig deep and perceive that you simply’ll be capable to sleep sooner or later, simply not proper now,” James stated, wanting drained after the sport. “This isn’t the time to relaxation or overlook about an project. You’ll have loads of time after a recreation and the following day to form of relaxation and decompress as a lot as attainable.”

Relaxation is tough to come back by within the playoffs. Although the Lakers and the Grizzlies had a kinder schedule than some groups bought, with two days off between every of the primary three video games, they’re now taking part in each different day with more and more excessive stakes. The Lakers’ first probability to complete off the collection will are available in Sport 5 on Wednesday in Memphis.

“The closeout recreation is at all times the toughest recreation of the collection,” James stated. “It’s essentially the most tiring one.”
