At least the Spurs talked a good game.

After returning from another successful rodeo road trip perched firmly atop the Western Conference, the Spurs vowed not to squander a home-heavy closing kick that would see them play 17 of their final 24 games in the comfort zone of the AT&T Center.

Talking the right talk, but failing to walk the walk, the Spurs welcomed themselves back from the road Wednesday by promptly dropping the first game of a six-game homestand, losing 105-101 in overtime to a Phoenix team bringing up the rear in the Western Conference.

“We kind of relaxed after such a long road trip,” said guard Manu Ginobili, whose missed foul shot at the end of regulation would loom large. “And this is what happens in the NBA when you don’t play your best.”

Playing at home for the first time since Feb. 2, after a 7-2 rodeo trip, the Spurs turned in a clunker that could come back to haunt them in April.

The Suns’ Wesley Johnson sent the game into OT with a 3-pointer at the fourth-quarter horn, and Phoenix limited the Spurs to one point and no field goals in the extra frame.

The loss was the Spurs’ first in San Antonio since Nov. 19, halting an 18-game home winning streak that was the third-longest in franchise history.

Despite a lackluster showing for much of the night, the Spurs (45-14) seemed poised to pad their record anyway, ahead by three and with the normally reliable Ginobili at the foul line with 3.7 seconds left in regulation.
