Terrence Jones had a fantastic game, scoring a career-high 24 points off 10-of-12 shooting. The second-year forward hit his first eight shots and also pulled down nine rebounds.
Five other Rockets players recorded double figures, and Dwight Howard posted a double-double with 10 points and 11 boards.
Courtney Lee led the Celtics with 17 off the bench.
Houston shot 57 percent from the floor while Boston managed to hit on only 32 percent of its field-goal attempts.
Let's break down this one.
Terrence Jones Continues to Impress
Since being inserted into the starting lineup, Jones is averaging a double-double, and he had the best game of his career on Tuesday night.
The forward scored 11 points in the first quarter alone, getting out in transition, attacking the basket and even showing some range by knocking down a three.
He was also a presence defensively, showing good timing with two blocks and doing an outstanding job of disrupting the Celtics' pick-and-roll sets. He displayed great instincts, doing a fine job of getting out and hedging screens.
Jones keeps getting better and better and looks like he is becoming an integral piece to this Rockets team. Either that, or he will serve as some mighty attractive trade bait at the deadline.
Rockets Love to Block and Run
Houston broke this game open early by swatting shots and then taking advantage of the loose ball by picking it up and getting out on the break.
The Rockets blocked three Boston shots within the first few minutes and turned all of them into transition points, and the C's were never able to recover.
Howard of course served as a spectacular intimidator in the paint, blocking three shots and altering countless other possessions with his presence in the lane.
As a team, Houston blocked 10 shots.
Houston's Halfcourt Offense Still Needs Work
While the Rockets offense looks great when they can get out in the open floor, it really bogs down when they are forced to generate points in the halfcourt set.
It does need time to gel, as Howard is still integrating himself into the system, but the ball movement really needs to improve. There is a lot of standing around and waiting for something to materialize instead of going to work and creating it themselves.
Celtics Still Aren't Very Good
While that four-game win streak and win at Miami did happen, the Celtics still have a lot to work on.
Boston looked absolutely clueless offensively for most of the night, and it was clearly spooked by Howard in the middle. The C's rushed up a ton of shots around the basket, some when Dwight wasn't even on the floor.
They also ran the shot clock down far too many times and had to force up poor, contested jumpers because of it.
Jared Sullinger was solid in this one, going for 10 points and eight boards, playing some fine defense on Howard and posting a minus-6 in a 24-point loss, but other than that and some nice shooting from Lee, the C's were a dumpster fire in this contest.
The Celtics lost four in a row to start the season, then won four in a row and have now dropped four straight again.
