MINNEAPOLIS -- Needing a win to keep their playoff hopes alive, the Houston Rockets did their part, emphatically.

James Harden led all scorers with 34 points as the Rockets won their second game in a row, blasting past the Minnesota Timberwolves 129-105 on Monday.

Trevor Ariza added 21 points for Houston, which is vying for the eighth and final playoff spot in the West. With Utah losing on Monday night, the Rockets can clinch a playoff spot with a win in their final game on Wednesday.

The Rockets hit 15 3-pointers on Monday as their recent streak of hot shooting from long range continued.

"We can only control what we can control. We know that we're good enough to win games when we're not playing tight, when we're having fun, when we're sharing in each other's success and each other's joy," said Rockets interim coach J.B. Bickerstaff. "That's the way the game should be played. It should be fun, it shouldn't have to be tight….We just got to enjoy playing the game, enjoy the competition of it and enjoy going to war with your teammates."

Minnesota was led by Shabazz Muhammad, who had 23 points off the bench, but the Timberwolves saw their three-game winning streak come to an end. Zach LaVine chipped in with 21 for the Timberwolves.

"It's definitely disappointing. We see from the get-go we came out flat," Muhammad said. "Houston jumped on us from the get-go, and it doesn't matter that we're not playing for anything. There's a certain sense of urgency. Coach is really disappointed in our effort. We just played so well in those last three games and we kind of moved a step back, which is not good for us."

Houston led 15-13 with seven minutes to play in the opening quarter, then went on a 23-8 run to increase its lead to 38-21 after the first period -- Minnesota's largest opening-quarter deficit of the season. The Rockets led by as many as 23 in the second quarter and settled for a 68-47 advantage at halftime, paced by 23 points from Harden. Dwight Howard added 17 for Houston, while LaVine was Minnesota's leading first-half scorer with 17.

Howard and Minnesota's Nemanja Bjelica each had six first-half rebounds. Bjelica finished with 14 rebounds for the game.

The Rockets kept their collective feet on the gas in the third quarter, which was mostly devoid of defense in either end of the court. Houston kept bombing away from three-point range and emerged up 103-74 after 36 minutes.

"It was important for us. This is our playoff opportunity," said Harden. "We want to come out this entire game and just put the pressure on from the beginning of the game. We got out to a big jump and just rode that wave the whole game."

Bright spots were few for the Wolves, who had swept a three-game road trip last week, becoming one of just two teams to get a win at Golden State this season. Despite being well out of the playoff race, those wins were signs of hope.

"Even though we're always disappointed when we lose, we understand that they're young and we understand there are going to be nights like this," said Wolves interim coach Sam Mitchell, dismissing the notion that his team is tired. "We as coaches, to our credit this year, we haven't given them excuses and to their credit they haven't looked for any."

The 12 points by Minnesota forward Karl Anthony-Towns made him the franchise's all-time rookie scoring leader, surpassing the 1,473 points amassed by Christian Laettner in the 1992-93 season.

It was the third time this season Minnesota has allowed 129 points.
