Quick turnaround? OK. Starting center out with an injury? No problem. Syracuse has overcome every obstacle thrown in its path.

“Syracuse basketball is about being ready to play and being consistent,” coach Jim Boeheim said. “We’re usually ready to play.”

The Orange (30-4) meet Butler (30-4) on Thursday night in the semifinals of the West Regional at Salt Lake City, and the fifth-seeded Bulldogs already have a leg up. They’ll have one more day to rest than top-seeded Syracuse.

“I think it’s a tough turnaround for us. We have to go a long ways. They did us no favors,” Boeheim said. “But we have to do what we’ve been doing. That’s the good thing. We don’t have to do anything other than play the way we’ve been playing. That’s what we’ve done all year.”

It’s simply a continuation of the pattern of the first two rounds in Buffalo, N.Y. Syracuse’s first game, against Vermont, was the last one of the day and didn’t end until midnight Friday. The Orange were then immediately scheduled to play Gonzaga in Sunday’s first game, which started just after noon.

There hasn’t been much to worry about, really. Syracuse won its first two games by an average of 22.5 points — and without starting center Arinze Onuaku, whose status for the remainder of the NCAA tournament is unknown.

His absence was sorely missed in the opening minutes against Gonzaga. Elias Harris opened the game with a soaring alley-oop dunk, catching the Syracuse defense by surprise. Harris continued his personal attack as the Zags kept feeding 7-foot center Robert Sacre in the lane in an effort to get Onuaku’s replacement, forward Rick Jackson, in foul trouble.

The strategy worked when Jackson went to the bench with his third foul with 8:58 left in the first half and Syracuse clinging to a one-point lead.

Enter 7-foot freshman DaShonte Riley, who had logged 125 minutes in the 14 games he saw action during the season and another 12 in the first-round win over Vermont.

“There’s no question that was a very trying moment because they were playing well, and they’ve got post people that were hurting us,” Boeheim said. “He made a couple of plays in there that made a big difference. I mean, a big difference.”

Despite two embarrassing moments — Riley was forced to take a 3-pointer when the shot clock was about to expire and let a Gonzaga player rip the ball out of his big hands and start a fast break the other way — he acquitted himself well.
