The Phoenix Suns will not have the services of star guard Devin Booker when they take on the Oklahoma City Thunder Sunday. Booker is dealing with a hamstring injury and missed the Suns' last game against the Memphis Grizzlies.

Booker has been fantastic when healthy as he continues to be one of the few bright spots for a struggling Suns franchise. He is averaging 27.8 points, 4.5 rebounds and 6.8 assists. He is undoubtedly one of the up-and-coming superstars in the NBA. Unfortunately, team success is something that has been very elusive for him and his team.

After not making the playoffs last season, Booker said this summer it was time to start winning and make a run to the playoffs. It's early in the season, but it seems that the Suns likely will not make the playoffs based on their 1-4 start.

Without Devin Booker, the Suns will have to rely even more on the play of No. 1 overall pick DeAndre Ayton, who has played great for them as well. He is currently averaging a double-double with 17.8 points and 10.2 rebounds per game on an incredible 69.6 percent field goal clip.

On the other side, the Thunder actually have a worse record than the Suns at 0-4. They are coming off a disappointing loss against the Boston Celtics in which Russell Westbrook struggled down the stretch. Westbrook is questionable himself with a sore shoulder.
