The Suns have won the games in which they had the best chance — at home against Utah and Portland and at New Orleans with a day of rest. What is more telling about how the Suns might be underbilled — or at least competitively entertaining — is how they fared on the road this week in less desirable situations. After taking a fourth-quarter lead before losing Sunday at power Oklahoma City, the Suns played on the second night of a back-to-back set and were within a possession for nearly an entire second half before another power, San Antonio, prevailed 99-96 Wednesday night at AT&T Center. The Suns (3-2) shook off a double-digit, first-quarter deficit for the second consecutive night, but the Spurs’ precision experience proved too much for the Suns’ youthful fearlessness. Spurs guard Tony Parker scored 15 of his 20 points in the fourth quarter, including the final six decisive Spurs points. “That (experience) makes it two times as hard because even good defensive teams have a hard time stopping it,” Suns forward P.J. Tucker said. Tucker had been scoreless but gave the Suns their first fourth-quarter lead with a 3-pointer with 1:35 to go. When Parker answered with a jumper, Tucker set up center Miles Plumlee for a go-ahead reverse layup that put the Suns ahead 96-95 with 1:05 remaining. From there, the Suns unraveled, setting up Parker’s go-ahead scores when Gerald Green charged into Manu Ginobili and Eric Bledsoe slipped and missed a floater over Tim Duncan. Green took the blame for the loss, saying he should have pulled the ball out rather than drive early in the shot clock. “It’s one of those things where I got to just swallow it, but it’s like swallowing an apple,” Green said. The Spurs (4-1) led 99-96 after a Parker layup with 12.8 seconds remaining when the Suns overplayed an inbounds play but still had two shots to tie it. Bledsoe missed a difficult 3-point try off a well-defended, timeout play, but the rebound caromed out of bounds for a second chance. Green got loose to try a tying 3 that missed. Green, starting for the injured Goran Dragic again, made three 3s to make him 14 for 28 on 3s in the past three games. San Antonio controlled the Suns’ fast break well in the first half but the Suns kept pace with an 18-point, seven-rebound first half by Markieff Morris, who took advantage of the Spurs’ smaller lineups for a career-high tying 23 points. Plumlee added 15 points and six rebounds, going against Duncan (17 points, five rebounds) for the first time. Bledsoe tallied 14 points and five assists while not making any of the team’s 18 turnovers. His backup, Ish Smith, played 18 reserve minutes in which the Suns outscored the Spurs by 12. “The face that we’re there to win, even after all our struggles, says a lot about our character,” Plumlee said. “That’s where experience really shows is in crunch time. There’s only one to get it, to go out there and get in those situations.”
