SAN ANTONIO (AP) -- After staggering at the end of a long trip, the San Antonio Spurs were reminded how nice it is to come home.
The loss was the seventh in the last eight games for Seattle.
The victory ended a two-game losing streak at the end of San Antonio's eight-game "rodeo trip," which began Jan. 30 at Utah. San Antonio has taken this trip for the past four seasons while a rodeo was held at the AT&T Center.
"It felt good to be home and playing in front of our fans," said Parker, who scored all eight of his first-half baskets on layups. "I wanted to make sure we didn't come out flat."
San Antonio built up a first-half lead behind Parker's layups, then buried the Sonics under a barrage of 3-pointers in the second half. The Spurs went 8-for-14 from behind the arc after the break and finished 11-for-21 in the game. Michael Finley connected on four 3s, including the 1,000th of his NBA career.
Finley credited his performance to five days of rest during the All-Star break.
"It helped to get the energy back, so I was able to get my legs under me and knock down some shots," he said.
Bowen scored a season-high 17 points and Finley added 14. Tim Duncan had 13 points and 16 rebounds.
The Spurs extended a seven-point halftime lead into double digits early in the third quarter, and got it over 20 early in the fourth.
Rashard Lewis (8 points) left the game in the second half with a right-ankle sprain. He is averaging 21 points, but has been held under 10 in three of his last four games.
"We've got some guys that are really beat up right now," Lewis said. "Guys are starting to fade and I don't know whether we are wearing down or giving up, but nothing is going our way right now."
Allen suggested the Sonics might not be trying hard enough.
"When the effort is in question, the ball goes in different directions and the ball doesn't always bounce your way," he said. "When you are playing hard, you get more bounces your way."
Parker made layups on three straight possessions as the Spurs took a 7-0 lead, but Seattle fought back and took a 13-11 lead midway through the opening period on a 21-footer by Ridnour.
Bowen followed with his first 3-pointer and later Finley added another 3 as San Antonio outscored the Sonics 16-7 to end the first.
The Spurs lost another seven-point lead in the second as the Sonics went on a 13-4 run. Allen hit a pair of 3-pointers for his first field goals of the game to even the score at 31, and Ridnour put Seattle ahead with two free throws.
But Bowen's second 3-pointer started a 15-4 burst over the final five minutes of the half. The run included two more layups by Parker and back-to-back baskets by Nazr Mohammed.
Parker scored 20 of San Antonio's 46 first-half points.
