It’s rare that a game in any sport comes down to one factor. Such was the case Wednesday at the AT&T Center, where the Spurs dominated after halftime after cutting their turnovers from 10 in the first half to just three in the second. The improved ball control kept the Bulls in the halfcourt, the type of game in which they had no hope of keeping up with the Spurs. Especially with Manu Ginobili coming off the bench for yet another game-changing performance in Tony Parker’s stead: 18 points and nine assists in just 25 minutes. The Spurs jumped out to a quick 8-0 run, but the Bulls answered with a pair of epic surges, first 15-1 and then 15-0 to take a 46-32 lead midway through the second quarter. The Spurs then scored 11 straight to pull within five, setting the stage for a dominant second half in which they outscored the Bulls by 23. Ginobili and Tim Duncan led five players in double-figures with 18 apiece.
