LONDON Halftime ended. Showtime began.
The U.S. mens Olympic basketball team needed a while but eventually put on the show fans came to see, beating Tunisia 110-63 on Tuesday night.
Finally pulling away when coach Mike Krzyzewski started the reserves to open the second half, the Americans had six players in double figures and improved to 2-0 in the tournament.
Krzyzewski insists he planned to start the second unit even before a lackluster first half and said he there was nothing bad about the Americans performance.
Its not going to a perfect thing, you know? he said. But overall tonight was good. I mean, come on, it was 110-63.
True, it was a 47-point blowout, but the lead was just 13 at the half, and he sure didnt look pleased as he quickly walked to the locker room. But if he didnt see anything wrong, the players sure did though they werent concerned.
We told him, dont get worried, Carmelo Anthony said. Were all right.
They sure were.
Anthony, Deron Williams, Russell Westbrook, Kevin Love and Andre Iguodala opened the third quarter with a 21-3 run, turning a surprisingly close 13-point lead into a 67-36 bulge before any of the more celebrated starters finally got to play in the second half.
That was a great lift, man. Thats the best thing about this team, theres no drop off, said Kevin Durant. Weve got All-Stars off the bench. Those guys did great job for us.
Anthony and Love scored 16 points apiece for the Americans, who gave the fans the dunk show they expected once the game was in hand. Durant had 13, and rookie Anthony Davis dunked his way to 12.
But they had to work hard to make this one look easy.
The game against the Olympic newcomers wasnt expected to be close for more than a few minutes. The daily preview in the press center said it could prove to be one of the most lopsided matchups of London 2012.
The Americans maybe expected this simply would be like a practice they even decided to cancel Wednesdays workout some 11 hours earlier.
Yet they found themselves in a five-point game late in the first half, launching 3-pointers when they couldnt be stopped inside.
The second unit simply appeared to compete much harder, with Williams even playing one defensive possession with one shoe after the other fell off. Love briefly had to come out after banging knees but was able to return later.
Its a different game to get ready for, and I thought as a team overall we were ready, but it took like our bench to get us going defensively, Krzyzewski said.
Makram Ben Romdhane scored 22 for Tunisia, the African champion playing in just its second Olympic game. A wire-to-wire loser Sunday against Nigeria, theyll be able to tell their kids their first Olympic lead came against the powerful Americans.
They could have absolutely have taken us to the cleaners, but Coach Ks discipline made sure that didnt happen, Tunisia coach Adel Tlatli said through an interpreter.
The Americans had played nothing but top-level opposition of late, beating Argentina and Spain in their final two exhibition games before opening with a 98-71 victory over France. They played like they expected a little breather so they mostly could concern themselves with adjusting to the Olympic basketball arena and the international officiating that had them so perplexed in the first half Sunday.
But nobody told the Tunisians they were supposed to easily go down.
They fearlessly began, with Ben Romdhane driving all the way for a dunk the type of athletic plays that usually are made by the Americans, not against them to take an 8-4 lead. Tunisia still led by three with 2:39 left in the period before the U.S. second unit ran off the final nine points for a 21-15 advantage.
Its a dream for us to see these kinds of players, but now we play with them, Ben Romdhane said.
Tunisia tried to outwork their more talented opponents, hustling for loose balls to set up second shots that usually missed.
The Americans missed all eight 3-pointers in the first, even worse than their 0-for-6 start Sunday, before Anthony nailed one to open the second quarter. Westbrook followed with a jumper for a 26-15 lead, and the expected U.S. blowout seemed to be under way.
Instead, Marouan Kechrid made consecutive 3-pointers a couple of minutes later that brought Tunisia within six points, and he made another one with about 3½ minutes left, pumping his fist back toward his bench after cutting the U.S. lead to 35-30.
Only then did the Americans finally get control of the game, rattling off 11 consecutive points with James behind-the-back pass to Durant for a dunk making it 46-30. The Americans led 46-33 at the half.
We knew that they were going to come out and play hard, Durant said. We missed some shots early on, and we gave up some easy baskets, but we came back and started fighting a little harder.
The teams met in the 2010 world championship in a similar game. The U.S. won 92-57, pulling away after leading by just six at halftime and holding the Tunisians to 27.8 percent shooting for the game.
The Americans were 17 of 22 (77 percent) on 2-pointers in the first half but missed 10 of their 12 3-point shots. They didnt need to worry about 3s much in the second half though those could become a problem against better competition because they got dunks whenever they wanted.
Westbrook scored 11 for the U.S., which plays Nigeria on Thursday.
