First the Lakers qualified for the postseason. Now all they have to do is show they're qualified to make a playoff run.

"It's not going to be easy," Coach Mike D'Antoni said, "but why should that be any different?"

The Lakers added five minute to their regular season but reached the Western Conference playoffs as the No. 7 seed with a 99-95 overtime victory over Houston Wednesday at Staples Center.

That means they veered away from a first-round matchup with Oklahoma City and instead will open a best-of-7 series at San Antonio on Sunday. Before they took the court against the Rockets, Utah's loss to Memphis assured the Lakers of a postseason berth somewhere.

Then, after rallying from an 11-point deficit, they took a three-point lead before Chandler Parson's 34-foot 3-pointer at the buzzer after a wild scramble sent the game into overtime.

"I would have died out there if that shot had gone in and we weren't in the playoffs," D'Antoni said. "They'd have carried me right off."

Now they get to prepare for a postseason without Kobe Bryant, who was watching and tweeting as Pau Gasol picked up his second triple-double in three games, Dwight Howard came alive in the second half and finished with 16 points, 18 rebounds and four blocks, and Steve Blake had 24 points, seven rebounds and seven assists.

Antawn Jamison, Blake and Howard played the entire fourth quarter and overtime. Gasol played all of the fourth and all but 10.5 seconds of the overtime and the Lakers reached their high-water mark of the season at 45-37.

"I don't think it changed their mindset," D'Antoni said of Utah's defeat.

"We knew we wanted to win. I don't know if at the beginning of the game we were like 'Oh, we're in.' I don't think so. They wanted the seventh spot and they did it.'"

Gasol had 17 points, 20 rebounds and 11 assists and Jamison added 16 points.

"They brought us back, they deserved to take us all the way in," D'Antoni said.

It took the Lakers more than 2 1/ 2 minutes to score in overtime, but Gasol's short jumper gave them a 92-91 lead. Howard hit a short hook for a three-point lead, though Harden pulled the Rockets within a point with a drive.

Jodie Meeks then drove the baseline for a dunk with less than a minute left and the Lakers coaxed their lead to the end.
