The Rockets never would have thought they would "hold on" for a win on Sunday. They might have thought they'd run away with a win, easily take a win. Hold on did not seem likely to be necessary.

Yet, after holding off the Suns, 113-102, they knew taking a victory that was more difficult than necessary beat the alternative. Besides, they had greater concerns than style points.

Chris Paul left the game in the first two minutes of the fourth quarter and did not return. The Rockets said the plan was that he would be done for the day early and that he went to the training room for early treatment. But he did look to be struggling after beginning the fourth quarter with a jump shot.

The Rockets had already lost forward Trevor Ariza with a left leg injury in the first minute.

From there, they struggled through a ragged, often disjointed game, with the Suns even cutting an 18-point lead to seven in the fourth quarter. The Rockets put the win away with little difficulty.

James Harden struggled with his 3-point touch for a second-consecutive game, but still had 27 points with 10 rebounds and eight assists. The Rockets had six players in double figures, even with Ariza limited to that one minute and with the Rockets making just 29.7 percent of their 3s.

The Suns were led by Devin Booker, who had 31 points and 10 assists. T.J. Warren had 24 points. But even when the Suns made their fourth-quarter move, they did not seem much of a threat.

When Gerald Green put in a 3-pointer less than two minutes into the fourth quarter, the Rockets held an 18-point lead and began looking for the knockout.

As with everything else through the day, however, the Rockets never seemed to find a roll, with the game seeming much more difficult than necessary and with concerns that stretched beyond the score.

After making their first two shots of the fourth quarter, the Rockets made 3 of their next 11 with the Suns closing to within eight with 2 ½ minutes left. The Rockets did not make another shot, but did not have to. Clint Capela put in a pair of free throws, completing his double-double, and that was enough, with relatively little seeming necessary to secure the win.

The game was ragged from the start.

Thrilling as the free throw shooting contest of the first half was, the Rockets spent much of the night working to mix in some basketball. When they did in the final two minutes of the half, with three baskets made with players actually moving, they ended the half with Harden, Gordon and Mbah a Moute finishing at the rim to take the Rockets to their largest lead of the half, 60-53.

Most of the half, however, was as if designed to give an NBA-TV audience a nice Sunday afternoon nap. The Rockets and Suns combined to make more free throws (37) than field goals (34). The Rockets took more free throws than they had in any half this season, topping the 25 they put up in the first half in Phoenix. Suns did not take any in the first quarter, but 18 (two shy of the most in a quarter against the Rockets) in the second quarter.

That all worked to steal any rhythm from the game. While the Rockets shot well, making 51.5 percent of their attempts, they took fewer (33) than they had in a first half all season.

When they began putting attempts together in the second half, the Rockets also could string together buckets and built an 18-point lead. They could cruise from there, as it always seemed they could.
