Summing it up The Spurs’ first outing since their 19-game win streak was snapped in Oklahoma City wasn’t all extra passes and corner 3-pointers. Indeed, they’ll wait nervously for an MRI on Monday to determine the extent of the back spasms that sent Tony Parker to the locker room after just nine minutes. It marks the latest setback for Parker, who has been hampered by no less than five specific injuries this season. Otherwise, the Spurs (60-17) played about as well as could be expected, shaking off Parker’s early departure to take a 16-point lead, and pretty much cruising from there against a Grizzlies (45-32) team battling for its playoff life. It marked the Spurs’ 14th victory in the past 16 meetings since Memphis stunned them in the first round of the 2011 playoffs. “They’ve had our number for almost two years now,” Memphis point guard Mike Conley said. Player of the game Kawhi Leonard has been outstanding since his return from a broken hand. He enjoyed his best game yet, sinking 12 of 13 shots to tie his career-high with 26 points. As Manu Ginobili noted, much of the damage — 20, in fact– came on jumpers. Leonard wasn’t quite as active on defense, recording no steals or blocked shots. But then, he didn’t have to be while matched up against the likes of Courtney Lee and Tony Allen. Said Ginobili, “He was incredible.”
