DALLAS -- Dirk Nowitzki scored 18 of his 38 points in a flawless first quarter, and the Dallas Mavericks beat the Memphis Grizzlies 113-97 Wednesday night to match a franchise record with their 16th consecutive home victory.
Nowitzki made all seven of his field goals in the opening quarter, including a 14-footer at the buzzer, to go along with 4-of-4 free throws, four rebounds, two assists and two steals.
When he missed his first shot -- five minutes into the second quarter right after returning from an extended break -- the Mavericks had a 25-point lead. They needed almost all of that to overcome their own miserable stretches.
After trailing by as many as 27 before halftime, the Grizzlies got within 68-61 on Mike Miller's tip-in midway through the third quarter after Dallas missed its first 11 shots following halftime. Dallas led by 27 again early in the fourth before a 16-2 spurt by the Grizzlies.
Memphis scored the first 12 points of the third quarter before Nowitzki made the second of his two free throws. But by the time Nowitzki made a 3-pointer at the end of the third, Dallas was back up 89-65.
Nowitzki finished 14-of-20 with 10 rebounds and six assists. Josh Howard added 23 points and nine rebounds, and Devean George scored 15 points for the Mavs, whose last home loss was Dec. 7 against Detroit. They go for their 17th straight home victory Friday night against Houston.
Pau Gasol had 29 points and Miller 21 with five 3-pointers for Memphis, which lost for the sixth time in seven games and dropped to 3-21 on the road. Gasol had nine of the 22 Memphis turnovers.
One season after the teams met in the first round of the playoffs, the Grizzlies (12-38) are 28 1/2 games behind Western Conference-leading Dallas (40-9), which has the NBA's best record.
After sweeping that four-game playoff series last April, the Mavericks have swept this season's regular four-game set as well.
A week earlier in Memphis, the Mavericks held on for a 95-94 victory despite a pair of 30-footers by Miller and Chucky Atkins in the final 5 seconds. Dallas had played only once since, winning 94-93 over Minnesota on Saturday night.
Miller, who had 20 of his 32 points in the fourth quarter of the last meeting, started this one with another long 3-pointer. But that was the only time the Grizzlies led.
Howard responded with a 3-pointer that started a 10-0 run for Dallas. The Mavericks led 40-24 after the first quarter, then scored 12 straight points after Gasol's 6-foot hook shot to start the second.
After the Grizzlies got close in the third, they then had six turnovers in a five-minute stretch when George scored nine points for the Mavericks. Nowitzki hit consecutive baskets to end the quarter.
