CHARLOTTE, N.C. -- D.J. Augustin says he has no hard feelings when it comes to the Charlotte Bobcats -- even though they let him walk in free agency after the 2012 season. "Just a business," Augustin said with a smile. He sure took care of business Saturday night. Augustin played like a man with something prove, breaking open a close game by scoring 15 of his 28 points in the fourth quarter to help the Chicago Bulls hold off the Charlotte Bobcats 89-87 and get back above .500. The Bulls (22-21) have won 10 of their last 13 games. Augustin hit 4 of 5 shots from the field in the fourth quarter, including three 3-pointers. It was the third time in the last four games Augustin has scored at least 27 points. Augustin was drafted by the Bobcats in 2008 and spent four seasons in Charlotte before the Bobcats decided to go with Kemba Walker as their starting point guard. "Its always fun playing against your old team," Augustin said. "Im with the Bulls now and that is all that matters." Augustin spent time with Indiana and Toronto last season before joining the Bulls this past off-season. Chicago coach Tom Thibodeau called the 6-foot Augustin a "huge pickup." "We had a need and he had a need as well," Thibodeau said. "It was good for him and its been great for us and hes played better and better. He was ready when this opportunity came around. Its not only his individual performance, but what hes doing for our team." Joakim Noah added 11 points, 10 rebounds and eight assists for the Bulls, who have won 10 of their last 11 against the Bobcats. Taj Gibson had 13 points and seven rebounds, while Mike Dunleavy had 12 points and eight rebounds. Al Jefferson continued his hot play for the Bobcats (19-27) with 32 points and 13 rebounds. It was his ninth straight 20-point game. "Nobody is playing better than Al over the last eight or nine games," Bobcats coach Steve Clifford said. Jefferson said the discomfort from the ankle he sprained in the preseason is starting to subside. "At the beginning of the season I wasnt healthy," Jefferson said. "My ankle is feeling really good and Im not surprised how Im playing. I know I can play at a very high level when Im 100 per cent." But the Bobcats arent getting much production from other positions with Walker still out with an ankle injury. The starting frontcourt of Ramon Sessions and Gerald Henderson was a combined 9 of 26 from the field. "They double-teamed me and did a good job of keeping the ball out of my hands. So tonight, Kemba would have been needed," Jefferson said. "But its an opportunity for some other guys to step up and make a name for themselves." Chicago came in having defeated the Bobcats by an average of 27.5 points in the last four meetings in Charlotte, but this one was close throughout the first three quarters with 14 lead changes and neither team leading by more than six points. The Bulls were up 55-54 going into the final period and quickly extended that lead to 11 sparked by eight quick points from Augustin and six from Tony Snell. The lead would get to 12 before a frantic Bobcats comeback in the final minute, with Jannero Pargo knocking down a 26-footer with 3.4 seconds left to cut the lead to three. But Augustin made two free throws to seal the win. Jefferson hit a one-handed heave from just beyond half court as time expired, although it wouldnt matter. Chicago surrendered 112 point to the Los Angeles Clippers on Friday night -- the second-most theyve allowed this season -- but the leagues second-best defence returned to form against the Bobcats. They held Charlotte to 42 per cent shooting after allowing the Clippers to beat them with 59.3 per cent shooting. "We get knocked down but we always get back up and keep fighting," Augustin said. "That is the motto of our team." NOTES: Walker missed his fourth straight game with an ankle injury. ... Carlos Boozer has scored in double digits in nine straight games for the Bulls. ... Sessions had 11 assists for the Bobcats. ... The Bobcats had been outrebounded by 22 in the first two meetings, but held a 45-41 edge on the boards this time. Fjällräven Zaino Kanken No.2 .

Today, Craig takes a look at the four quarterfinal match-ups. HBI 1: Russia vs. USA It has been something, although not entirely, of a boom-or-bust cycle for USA over the past six tournaments. The Americans have reached the semifinals only three times during that period and won a medal each time – twice gold and once bronze. The U.S. is out to end a three-game losing streak against the Russians. HBI 2: Finland vs. Sweden Throw the records out when these two great hockey nations face off. Regardless of Swedens 18 goals in four Group games and Finlands mere five, its sure to be ultra-competitive. A reminder: Finlaand beat Sweden on home ice for gold last year, ending a five-game Finnish losing streak against the Swedes.dddddddddddd HBI 3: Slovakia vs. Czech Republic After getting smoked by Sweden and Switzerland, the Czechs finished with a convincing win over Russia. The Czechs have made significant strides in their U-20 & U-18 programs and a win vs. Slovakia would validate their return as a medal contender. The Czechs last won a medal in 2005 – a bronze. HBI 4: Denmark vs. Canada The clock strikes 12 tonight for the Cinderella Danes. It would take an upset of historic proportions for Denmark, coming off its first-ever Pool A victory, to beat Canada which has, to this point, redeemed its reputation for fast, skilled and competitive hockey with four resounding triumphs.
