The AP reports: With Kevin Garnett watching, Glen Davis helped keep the Boston Celtics hustling and winning. Davis, who moved into the starting lineup as Garnett was held out with a sore knee, had 19 points and matched his career high with 12 rebounds to lead the Celtics past the Atlanta Hawks 99-93 on Friday night. Ray Allen led Boston with 22 points and Paul Pierce had 21, but Davis was the key while filling in for Garnett. Boston coach Doc Rivers said his team won with “mental toughness.”
