The Hornets, playing at home for the first time after a grueling four-game trip, led 70-69 with 3:13 left in the fourth quarter, but the Pacers scored seven consecutive points, four coming from West.
"It's one of those things where our focus was to come out and we played a good first half, but in the second half we just didn't make many shots," Hornets guard Austin Rivers said. "We came out flat in the second half and to sum it all up you have to come out and play a full 48 minutes, not just one half."
New Orleans cut the deficit to 75-73 on Vasquez's three-point play, but Lance Stephenson scored off an offensive rebound and West added a turnaround jumper to secure the win.
The Hornets were 13 of 42 from the field in the second half, and had only seven free throws — making five — in the game.
"We couldn't get to the line," Williams said. "The NBA is cruel that way. We have to own it and move forward."
NOTES: West scored his 10,000th career point midway through the third quarter. ... Indiana improved to 16-12, and New Orleans dropped to 5-22.
