Phoenix Suns hold a 1-0 series lead over Dallas Mavericks, but center Deandre Ayton was left unimpressed by their performance in Game 1.
The two teams meet again in Phoenix on Wednesday and the Suns are 10/11 to win with a -6 handicap in the Point Spread, while Dallas are 21/10 in the Money Line.
Phoenix looked on course to claim a convincing win in the series opener as they opened up a 10-point lead by the end of the first quarter and led by as much as 21 points early in the fourth.
However, the Mavs fought back and moved to within five points in the closing stages, but Phoenix managed to cling on and claim a 121-114 win.
The Suns finished the regular season with the best record in the league, but haven't hit top form in the play-offs just yet.
Phoenix were taken to six games in the first round against New Orleans Pelicans and nearly blew a commanding lead against the Mavs.
The Suns may have seized the advantage by winning the first game of the series, but Ayton was far from satisfied with the performance and he says his team have to improve if they are to launch a serious bid for the championship.
"This is play-off basketball and it's unacceptable the way we closed it out," said Ayton, via USA Today.
Ayton led the scoring for the Suns on Monday with 25 points and Devin Booker added 23 with nine rebounds and eight assists, while Mavs star Luka Doncic led the game in scoring with 45 points, 12 rebounds and eight assists.
