CLEVELAND --- Back to even and back to Boston -- with authority.
LeBron James scored 21 points, jamming in a powerhouse dunk over a defenseless Kevin Garnett in the final 2 minutes, as the Cleveland Cavaliers beat the homesick Celtics 88-77 in Game 4 on Monday night to tie the best-of-seven series at 2-2.
Still stuck in a shooting slump, James dominated down the stretch and finished with 13 assists -- four in the fourth quarter. The Cavaliers, whose defense has been overlooked, held the Celtics to just 12 points in the final period.
Boston dropped to 0-5 on the road in the postseason, a stunning slip for a team that went 31-10 on the road in the regular season.
During a short visit to Ohio, the Celtics lost their momentum in the series but will head home, where they went 35-6 before the playoffs started. Boston hasn't lost at home in six playoff games.
Game 5 is Wednesday night, and Game 6 will be back in Cleveland on Friday.
James was just 7-for-20 from the floor, but he did everything else for Cleveland.
In the final 8:45, James had four assists, a 3-pointer and a right-handed dunk that became the signature moment of this series thus far.
With Cleveland leading 82-75, James drove past Paul Pierce on a screen near the foul line, head faked past James Posey, and then leapt over Garnett.
Garnett scored 15 points, with only two in the second half. Ray Allen finished with 15 points, and Paul Pierce had 13, but the Celtics' Big Three were only a combined 16-for-40.
