DALLAS, Dec. 2 (Ticker) -- Tracy McGrady had his best game as a member of the Houston Rockets, but Dirk Nowitzki had the best game of his career.

Nowitzki scored a team-record 53 points to offset the season-high 48 scored by McGrady as the Dallas Mavericks posted a 113-106 overtime victory over the Rockets.

Having already reached a season high by the end of regulation, Nowitzki kept Dallas from trailing in overtime by scoring the first 10 points of the extra session. The All-Star forward capped the surge with a 3-pointer that gave the Mavericks a 103-93 lead with 3:35 remaining.

"It was a great night," Nowitzki said. "I made my first couple of shots and that usually gets my confidence up and I was just trying to be aggressive."

Nowitzki went 15-of-32 from the floor and an astounding 21-of-22 from the line to become the first player to reach the 50-point plateau in the NBA this season.

"All night long I got to the line," said Nowitzki, who also added 16 rebounds while playing 50 minutes. "On nights like that you just can't settle for the jumper. Guys were leaning all over me so I drove inside and made them pay from the line."

After averaging just under 16 points in his last three games, McGrady easily eclipsed his previous season high of 32 points by going 19-of-36 from the floor, including 6-of-13 from the arc.

"That was exiting," McGrady said. "It was fun. I think that was good basketball right there; two guys at a high level. I hope the fans enjoyed it."

"It was amazing," Nowitzki said. "We double-teamed him (McGrady) and he just jumped over us and made shots. He's one of the best perimeter scorers in the league."

The two-time NBA scoring champion had only taken 20 or more shots in three of his previous 14 games.

"I had a long talk with coach (Jeff Van Gundy) and kind of had an understanding of what he wanted me to do," McGrady said. "He wanted me to be aggressive and make my team better."

"He was just playing," Van Gundy said. "I thought he was very assertive and that was good."

The two stars knew what they had been a part of and acknowledged it after the game.

"We sort of winked at each other a couple of times," Nowitzki said. "After the game, he came over and congratulated me. I congratulated him too."

"This is (the) number one (game I've been part of)," McGrady said. "I've never been part of a game when another guy scored 50. Just to be a part of that was an honor."

With Dallas leading 93-92, McGrady collected three consecutive offensive rebounds before drawing a foul with 27 seconds left in regulation. He made the first free throw before the second rimmed out.

Bob Sura had a chance to win the game in regulation for Houston, which has lost five straight, but his desperation 3-pointer fell short as time expired.

Jim Jackson, who shared the previous Mavericks' single-game scoring record of 50 points with Jamal Mashburn, added 17 off the bench for Houston.

"When you've got guys out there like that it's exciting to be a part of," Jackson said. "I wish we had come up with the win."

Marquis Daniels and Jason Terry each scored 14 points and Jerry Stackhouse 13 for Dallas, which won for the third time in four games.

"This was a classic shootout," Terry said. Like Bird-Jordan, Dominique-Jordan, just big classic. "Two young superstars in the league shooting it out, trying to do what they can do to will their team to victory."

Dallas needed the win after losing three of its last four games, including a 107-89 drubbing at the hands of San Antonio on Tuesday.

"I'm just glad we won to be honest with you," Nowitzki said. "It was so close and we had lost a couple of bad games. We decided to do whatever it took to win the game."
