In the Thunder's 122-118 overtime victory against Phoenix on Sunday night, the difference between the teams ended up being about 10 feet. While the Suns made a living from roughly 25 feet away, the Thunder survived at the free-throw line before a sellout crowd of 18,203 inside Oklahoma City Arena. Phoenix had 101 field-goal attempts and scored double what OKC did (42-21) from 3-point range by draining 14 of 31 shots. The Thunder countered by outscoring the Suns 37-8 from the free-throw line, tying a season-high with 47 attempts while Phoenix attempted just 14. The league's best free-throw shooting team (.827) once again won in its wheelhouse — the uncontested 15-footer. Despite the Suns' monstrous shooting totals from the floor, Thunder coach Scott Brooks said his team's second-half defense came through at clutch moments. “We made them take some tough shots,” Brooks said. “Unfortunately, they made some tough shots.” OKC survived on a night when scoring champ Kevin Durant needed 45 minutes to score 18 points while shooting 3 for 14 from the floor. Durant missed his first five shots and didn't convert his first field goal until burying a 3-pointer with 1:48 left before halftime. He had two field goals in the first 86 seconds of the second half, but didn't make another shot from the floor and missed a potential game-winning 20-footer at the end of regulation. “I can tell you now that there is no better guy who did better defensively on Durant than Grant Hill did tonight,” Suns coach Alvin Gentry said. “I just thought Grant was great.” Durant did convert 11 of 12 free throws, grabbed eight rebounds, had two blocked shots and two steals. Thunder point guard Russell Westbrook had a game-high 32 points and added 11 assists. Reserve guard James Harden scored 26 points on just 12 field-goal attempts. He also had six rebounds, four assists and two steals. Harden came up big in the final minute of overtime, converting a conventional three-point play, which was followed by a steal just 5½ seconds later. Serge Ibaka had 15 points, seven rebounds and four blocked shots. “Serge had some great blocks,” Gentry said. Reserve forward Nick Collison had 11 points and nine rebounds, while guard Daequan Cook added eight points in 19 minutes. “Everybody chipped in today,” Durant said. “Russell, Serge and James picked it up for me. It was a great win for us. We grinded it out.” The three players who came to Phoenix in a trade with Orlando on Dec. 18 torched the Thunder for 69 points (10 for 18 from 3-point range), 13 rebounds, eight assists and three blocked shots. In two games against the Thunder, guard Vince Carter is averaging 31.0 points and is a combined 12 for 24 from 3-point range. He had a team-high 29 points Sunday and swished a 3-pointer with 9.2 seconds left in regulation to tie the score at 109 and force overtime. Center Marcin Gortat had 20 points, eight rebounds and three blocks, while wingman Mickael Pietrus had 20 points and went 4 for 6 on 3-pointers. OKC is now 3-8 on Sundays and 6-1 in overtime this season. The Thunder (39-22) plays tonight at Memphis (35-29), which won 104-103 at Dallas on Sunday night after overcoming a 55-38 halftime deficit.
