SAN ANTONIO (AP) — Two down, two to go. The San Antonio Spurs are halfway to a fourth title and a chance to state their case as an NBA dynasty.

And LeBron James, you’re a witness.

Tony Parker scored 30 points, Manu Ginobili had 25 and Tim Duncan added 23 as the Spurs schooled Cleveland in championship basketball for three quarters, overpowering the overmatched Cavaliers 103-92 in Game 2 on Sunday night to take a 2-0 lead in the NBA finals.

San Antonio was vastly superior in every way imaginable — until the last five minutes.

The Spurs, clicking on offense and digging their sneakers in on defense, built a 28-point lead in the first half and were embarrassing the Cavaliers, who are in their first finals but didn’t show up until it was too late, getting within eight points in the final minutes.

The Spurs’ Big 3 of Duncan, Parker and Ginobili combined for 43 points — 10 more than the Cavs — in the first half and as both teams walked off the floor of AT&T Center, the arena’s p.a. announcer, Stan Kelly, summed up the first 24 minutes with a comment that would have been funny if it wasn’t so painfully true for Cleveland.

“Spurs by a bunch,” he said.

And at the same time, a fan held up a sign saying, “Bring Out LeBroom.”

James, limited to 14 points in his finals debut, scored 25 to lead the Cavaliers.
