team after completing basic training. During his time at Sangmu, he was given the chance to play in a more offensive role and posted his best statistic in scoring to date, averaging 16.1 points in 9 games, in the 2009–10 KBL Winter League. His good form did not go unnoticed and he was named in the national team for the 2010 Asian Games. He was discharged and returned to Anyang for the last few games of the 2010–11 season. While he was away, Anyang strengthened the team by drafting rookie guards Park Chan-hee and Lee Jung-hyun and center Oh Se-keun. Yang went unnoticed during the 2011–12 regular season but gained a reputation as a "big game player" for his clutch performances during the playoffs. The relatively young squad suffered the embarrassment of scoring only 41 points in the January game against eventual regular season champions Wonju Dongbu Promy and setting an all-time record for the lowest score in a league game. They eventually managed to win the KBL Championship that season, Anyang KGC's first ever championship title. The 2011–12 Championship-winning team was soon split up as Kim was traded to Jeonju KCC Egis while Park, Lee and Oh all enlisted for mandatory military one after another.

Anyang KGC met Seoul Samsung Thunders in the playoff finals and team morale was at a low after a fight broke out between his teammate shooting guard Lee Jung-hyun and Thunders player Lee Gwan-hee during Game 2. With top-scorer Lee Jung-hyun failing to score in the double digits and Anyang trailing by 11 points, Yang was forced to step up as their main shooter during the second half; he was a defensive specialist well-known for his poor field goal percentage, to the extent that opponents utilized the strategy of forcing his teammates to pass the ball to him around the perimeter. During Game 3, he scored 13 points, 5 rebounds and 5 assists, most of which were recorded during the fourth quarter and while nursing two injured fingers in his dominant hand. He opted against sitting out of Game 6 and scored a personal best record of eight three-pointers as Anyang KGC narrowly won the game and the final
