Carlos Boozer is gaining confidence with each game with his new team. Boozer scored 13 of his 29 points in a big third quarter and the Bulls beat the Oklahoma City Thunder 99-90 on Monday night.Boozer got a big free-agent deal from Chicago in the offseason, but missed the team’s first 15 games with a broken right hand. He appears to be picking up steam since he returned in Wednesday night’s 107-78 loss to Orlando, scoring five, 12 and 25 points in his first three outings before taking down the Thunder.Luol Deng added 19 points for the Bulls (11-8), which outscored the Thunder 29-18 in the pivotal third. Derrick Rose had 11 points and nine assists, but shot 3 for 13 from the field.Boozer and Joakim Noah had 12 boards apiece as the Bulls outrebounded the Thunder 52-39 and enjoyed a 19-11 edge in second-chance points.Kevin Durant led the Thunder (14-8) with 29 points, but played only three minutes in the third quarter. Nenad Krstic added 18 points in 22 minutes for the Thunder. Russell Westbrook had 15 points and seven assists, shooting 7 for 18.Rose and Westbrook each had their moments in a matchup of two of the up-and-coming point guards in the NBA.Westbrook heated up midway through the third, scoring seven points in one nice stretch, but Rose and Boozer powered the Bulls to an 82-66 lead entering the fourth.Boozer made a pair of acrobatic shots in the lane after getting fouled. Rose hit a whirling triple-pump layup, then closed the quarter with a banked 30-footer at the buzzer. After a tight first quarter, both teams put together runs in the second.Kyle Korver hit back-to-back 3-pointers during a 13-4 Bulls surge, capped by Deng’s 3 that upped the lead to 11 with 5:09 left in the half.Oklahoma City responded with an 8-0 run of its own, getting a 3-pointer from former Bull Thabo Sefolosha after a Korver turnover and a pull-up jumper from Westbrook.The Bulls improved to 2-2 since Boozer’s debut, and the quality of play seems to improve with each outing.
