Boston, MA (My Sportsbook) - Kevin Garnett scored 28 points, including the go-ahead layup with 21.4 seconds left, and the Celtics put a defensive blanket on LeBron James, holding the Cavaliers superstar to only two field goals, as Boston edged Cleveland, 76-72, in the opener of their Eastern Conference semifinal series. It was an uncharacteristic contest for a few standout players, but most notable was James' horrific 2-of-18 night from the field. He totaled 12 points, nine rebounds and nine assists, but had 10 of Cleveland's 18 turnovers. Boston's Paul Pierce and Ray Allen combined for just four points on 2-of-18 shooting. Allen was held scoreless for the first time since Feb. 26, 1997. Sam Cassell scored 10 of his 13 points in the fourth quarter for the top- seeded Celtics, who were pushed to seven games by Atlanta in the first round and then committed 23 turnovers Tuesday night. Rajon Rondo totaled 15 points and Kendrick Perkins pulled down 12 rebounds, while Garnett had eight boards. Zydrunas Ilgauskas had 22 points and 12 rebounds for the Cavs, who also got 13 points from Wally Szczerbiak. Cleveland shot just 30.7 percent from the field. Game 2 is Thursday night, again at TD Banknorth Garden. HASH(0x9d7dd60)
