With a little less than four minutes remaining in the third quarter and the Bobcats leading 69-65, Charlotte took off on a two-on-one break following a Miami turnover. Approaching the hoop from the right side of the court, Sessions had a half-step on James, who was seeking a pseudo-chasedown block coming across Sessions' left side.
Sessions lifted off from just outside the protected circle, opting for a one-handed dunk attempt, as James challenged with his right hand. The two players met near the rim, but Sessions was able to finish the slam over the top of James, bringing the home crowd to its feet.
Here's a look at the approach.
This shot of the apex meeting shows how the split-second, bang-bang dunk was decided by a matter of inches.
Sessions finished with 16 points (on 6-for-10 shooting) and five assists for the Bobcats, who fell to 17-25 with the loss. Al Jefferson scored a team-high 22 points (on 10-for-23 shooting) and 14 rebounds for Charlotte.
James led Miami with a game-high 34 points (on 13-for-25 shooting), eight rebounds and six assists. Chris Bosh added 25 points (on 10-for-16 shooting) and seven rebounds for the Heat, who improved to 29-11 with the win. Video via YouTube user NBA
