LAKE BUENA VISTA, Fla. — The Houston Rockets didn’t show up for Game 4 against the Los Angeles Lakers until it was too late.

They can’t do that again Saturday in Game 5 — or else.

For the second time in these playoffs, the Rockets’ season is on the line. The Lakers lead Houston 3-1 in their Western Conference semifinal series and could clinch their spot in the West finals with a win on Saturday night at Walt Disney World. It is the only game on Saturday’s NBA schedule.

Houston has won an elimination game already; it beat Oklahoma City in Game 7 of the first round. Rockets coach Mike D’Antoni doesn’t want his club thinking about trying to win three games now, preferring instead to simply focus on getting one.

“We’ve got to win the next game,” D’Antoni said. “It’s a one-game series and then we’ll see what happens.”

The Lakers dropped Game 1 and trailed going into the fourth quarter of Game 2. They outscored the Rockets by 10 points in the final period of that game to even the series, beat them by 10 points again in Game 3 and 10 points yet again in Game 4.

If They Do That on Saturday, They’ll Be Leaving the Bubble Before the Weekend Is Over

LeBron James is on the brink of another conference finals, and said he’s seeing a Lakers team that is in its first playoff run together continuing to grow. He thought the Lakers played 43 good minutes in Game 4; a five-minute stretch of the fourth where Houston outscored Los Angeles by 16 points and made it a two-possession game was the omission from his tally.

“We want to strive for something better than that,” James said. “We want to work the game plan for 48 minutes. … We’re still a team that’s growing. We’ve got some guys who have not been part of the postseason. This is our first run together.”

NBA scoring champion James Harden was just 2 for 11 from the field in Game 4 for Houston, and D’Antoni said the team played without “spirit” for much of that game.

If they do that on Saturday, they’ll be leaving the bubble before the weekend is over.

“We know what we have to do,” said Russell Westbrook, who led Houston with 25 points in Game 4. “It’s going to take a lot of effort. It’s going to take everyone being uncomfortable in their role and making sure that we understand that we all have to sacrifice some of the things we may love to do, but we got to scramble. That gives us the best chance to win games.”

A look at Saturday’s game:

Rockets Vs. Lakers

Los Angeles leads 3-1. Game 5, 8 p.m. EDT, ESPN.

— NEED TO KNOW: The Lakers have taken away Houston’s biggest weapon — the deep ball. The Rockets have taken a total of 63 3-pointers in the most recent two games of this series, a very low number for a team that took 61 in a single game earlier this season. If Houston doesn’t get on track, James will be headed to the conference finals for the 11th time in his career.

— KEEP AN EYE ON: Harden. Game 4 was just the eighth time in his career — and the first since 2015 — when he played at least 39 minutes in a game and made no more than two field goals. The Rockets need him to have a bounceback game in the worst way.

— INJURY WATCH: The Lakers were missing two players Thursday. JaVale McGee missed Game 4 with an ankle problem and Dion Waiters is out with a groin issue.

— PRESSURE IS ON: Houston. All on Houston. There has been tons speculation about D’Antoni’s future with the team going forward for much of this season, and a five-game loss in the second round typically leads to big changes when a franchise has championship aspirations.
