"People are going to leave him for that shot," Duncan said. "His entire career they have and I still don't know why. He loves to line it up and we love for him to take that shot."
Bowen tied his career high with six 3-pointers and scored 18 points, leading the Spurs to a 110-91 victory over the Seattle SuperSonics on Tuesday night and a sweep of the four-game season series.
"It's great when you get an opportunity to shoot that many times when you're open," said Bowen, who was 6-of-9 behind the arc. "I got a chance to get some shots up. As compared to other games, it may not be like that. It's always good. You know, I've been here before."
Bowen has hit six 3s twice before in his career, including once earlier this season.
Tony Parker had 16 points and Duncan added 14 for the Spurs, who had five players in double figures.
Though the game was rarely close, it wasn't as bad as the beating the Sonics took late last month, when the Spurs beat them 120-79 for one of Seattle's worst home losses in franchise history.
The Sonics' 19-point loss Tuesday was the closest they've come to the Spurs all season.
"They're a good team, period," forward Rashard Lewis said. "They just show how far ahead they are of us. We've got a lot more learning to do. A lot more improving to do."
"Every time we doubled on Duncan ... they found the open man on the wing and they just shot well from the 3-point line," Lewis said.
Only four Spurs players didn't hit a 3-pointer in last month's rout, when San Antonio's 16 3s established a franchise record.
The 3s were contained to two players Tuesday -- but there were still plenty of them. And that was even without Brent Barry, a 45 percent 3-point shooter who is third in the league. He was out with back spasms.
Bowen's last 3 of the game, which he hit from the corner with 5 minutes left in the third, gave the Spurs a 20-point lead.
Michael Finley hit three 3s to help the Spurs finish 9-of-21 (43 percent) from behind the arc. Seattle was 2-of-8 (25 percent). Finley, who started in place of Barry, had 13 points and has scored in double digits in his last six games.
Fabricio Oberto had 11 points and 10 rebounds for San Antonio.
Down 26 points to open the fourth, two short of their biggest deficit of the game, Seattle went on an 8-0 run to make it 91-73. It was the closest the Sonics got in the fourth.
Spurs coach Gregg Popovich subbed out his last starter about three minutes into the period. Only starter Damien Wilkins remained in for Seattle until the end.
The Spurs outrebounded the Sonics 41-22.
"They have two 7-footers on the floor. We have two forwards. They're a lot longer than we are, they got a lot of those rebounds and I don't know what else to say," Sonics coach Bob Hill said.
The Spurs also had 26 assists, including seven from Duncan, to the Sonics' 18.
"If one guy's got a shot he takes it," Seattle's Nick Collison said. "If he doesn't, he just moves the ball and they play like that and it's tough to catch up."
