For lengthy stretches on Wednesday, it appeared that Houston Rockets guard James Harden was alone on an island, scoring at will because the situation demanded it. But even Harden could carry the short-handed Rockets only so far, especially when guard Eric Gordon, who returned from an eight-game injury hiatus only to depart with residual knee soreness, proved unfit to help Houston close the game. What remained was Harden scoring a season-high 58 points, only to run out of gas in a 145-142 overtime loss to the Brooklyn Nets.
