BEIJING, April 3 (Xinhuanet) -- The Boston Celtics reached two milestones — matching the NBA record for best single-season turnaround and winning 60 games for the first time in 22 years. And no one was more surprised than coach Doc Rivers.

    "Did we do that?" coach Doc Rivers said of the 36-game improvement. "Thanks for telling me. I didn't know."

    They did it with a 92-77 win Wednesday night over the Indiana Pacers in which they led by at least 13 points for the last 2 1/2 quarters.

    Boston's 60-15 record is the NBA's best just one season after its 24-58 mark was the second worst. The only other team to improve by that much was the San Antonio Spurs, who went from 20-62 in 1996-97 to 56-26 the next season, Tim Duncan's first.

    The Celtics also added a dominant player in the offseason, Kevin Garnett, who had 20 points and 12 rebounds Wednesday.

    Boston was 67-15 in 1985-86, when they won the most recent of its 16 NBA championships. That was The Celtics' sixth 60-win season in a seven-season stretch.

    Boston won its fifth straight and increased its Eastern Conference lead to 6 1/2 games over Detroit, which was idle. The Celtics lowered their magic number for clinching the No. 1 seed to two.

    Indiana dropped into a tie with New Jersey, four games behind Atlanta, which currently has the final playoff spot in the East. The Hawks beat Toronto 127-120 in overtime.
