James, Cavaliers Stuff Celtics in 4th To Even Up Series

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 two 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 during the regular season. During a short visit to Ohio, the Celtics lost their momentum in the series but will now head home, where they went 35-6 before the playoffs started.

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 the Cavs, who are attempting to overcome an 0-2 deficit for the second time in two years.

In the final 8:45, James had four assists, a 3-pointer and a right-handed dunk that rattled Quicken Loans Arena and became the signature moment of this series.

With the Cavs leading 82-75, James drove past Paul Pierce on a screen near the foul line, head faked past James Posey and then posterized Garnett, the league's defensive player of the year. As Cavaliers fans erupted, a scowling James stormed back on defense.

Although James is shooting only 20 of 78 (26 percent) from the floor, the only numbers the Cavs care about are the pair of 2s that show this series is as tight as possible.

Garnett scored 15 points, but only two in the second half, as Cavs forward Anderson Varejao harassed Boston's All-Star all night. Ray Allen had 15 points and Paul Pierce 13, but the Celtics' Big Three were only a combined 16-of-40.

James missed his first six shots in the fourth before draining a 3-pointer in front of Boston's bench with 3:17 remaining to give the Cavs a 79-73 lead. After the ball swished through the net, James made an it's-about-time shrug.

After a bucket by Pierce, James dished to Daniel Gibson for a 3-pointer as the Cavs opened a seven-point lead.

At the other end of the floor, the Cavs swarmed all over the Celtics, giving the league's best defensive team a dose of what they usually do to opponents. Cleveland contested every shot, and even when the Celtics had open looks, they missed.

Garnett inexplicably sat out the first five minutes of the fourth, and made just 2 of 9 shots after going 4-for-4 in the first.

Gibson and Wally Szczerbiak added 14 points apiece, Varejao had 12 and made two awkward jumpers in the final 1:10 to put the Celtics away.

James was on the floor nearly three hours before tip-off, working on his outside shot with assistant coaches Chris Jent and Lloyd Pierce, who helped him with his jumper off high pick-and-rolls. As James hoisted shots in the nearly empty arena, a few ushers, security guards and other Cavs employees watched, hoping this would be the night the All-Star forward re-discovered his outside touch.

"Just trying to catch a rhythm," James said about his early arrival.

It was the first time in this postseason that James came in before a game for extra work. He did it last year following two sub-par performances in the conference finals against Detroit, and rebounded to lead the Cavs to four consecutive wins.
