On January 20, Walker recorded his first head-to-head win against LeBron James, after having begun his career 0–28 against him. Posting 20 points, seven assists, four rebounds, and a steal, he helped the Celtics come away with a 139–107 blowout victory over longtime rivals the Lakers. Three days later, Walker was named to his fourth consecutive All-Star nod, being selected as an Eastern Conference starter.
