The Milwaukee Bucks will not always hit the height of their potential, but Damian Lillard suggested Tuesday's big win over the New York Knicks can be a sign of what is to come.

The Bucks ran out 146-122 winners over the Knicks in their NBA in-season tournament quarter-final.

Giannis Antetokounmpo had 35 points and 10 rebounds, while Lillard contributed 28 points, as the Bucks, who are second in the Eastern Conference, teed up a semi-final against the Indiana Pacers in Las Vegas.

Lillard warned it was too much to expect the Bucks to perform like that in every game, but he said the team have laid down a marker.

"I thought this was probably our best offensive game," said Lillard.

"That doesn't mean we're going to turn into a team that does that every night, but I do think we have that type of explosiveness.

"We can't depend on having these types of nights every time, but it's definitely a look at the kind of nights we can have offensively.

"It's been some bumps in that process where we don't play so great some nights but we're still able to win those games.

"I think now is just starting to get a little smoother, knowing where we should be on the floor, knowing how to give each other outlets, knowing how to help each other be who we are.

"It's not perfect, but I just like that we're showing improvement and it's carrying over and you can see it on the floor."

Lillard added that winning the in-season tournament would be a statement of intent.

"You come out of this thing on top, the last team standing, I think it's a pretty strong statement," he said. "It's something that everybody around the league has to respect."

"Tonight was a huge step. We wanted to get to Vegas," Bucks coach Adrian Griffin said.

"But when we get to Vegas, we've got to take care of business. We still got two games to win there."
