The Cavaliers took a commanding 3-0 series lead over the Celtics on Thursday with a 103-95 victory at TD Garden. James led the way for Cleveland all night, and helped seal the victory with an emphatic block of a Turner dunk attempt late in the fourth quarter.
With a little more than a minute remaining and Cleveland leading 98-92, Turner attacked the paint at full speed from the top of the key. As he watched the drive unfold, James slid over from the left block to position himself in front of the rim as Turner launched for a right-handed dunk. James proved up to the challenge, rising high to swat the attempt away with his left hand.
At the next dead ball, the TNT cameras appeared to catch James telling Turner: "You tried!"
The swat happened to represent a little bit of revenge for James, who was tackled to the ground by Turner earlier in the game. The officials hit Turner with a flagrant foul 1 on the play, a designation that applies to contact that is deemed unnecessary.
James finished with a game-high 31 points, 11 rebounds, four assists and four steals. Kevin Love added 23 points and nine rebounds for Cleveland.
Turner posted a team-high 19 points, eight rebounds and eight assists. Avery Bradley added 18 points and four rebounds in a losing effort.
Cleveland will have a chance to sweep Boston when the teams take the court for Game 4 on Saturday.
