The Phoenix Suns have dropped four straight games, but they’ll look to get back on track when they host the banged-up Milwaukee Bucks on Saturday.

Devin Booker has been scoring at an elite rate, and my Bucks vs. Suns predictions expect a strong performance from the franchise cornerstone in a comfortable win.

Here are my best free NBA picks for this late-night matchup on Saturday, March 21.

Bucks vs Suns prediction

Bucks vs Suns best bet: Devin Booker Over 27.5 points (-120)

Over his last 10 games, Devin Booker has averaged 30.3 points. In that span, he scored 28+ six times and finished with 27 twice more. He provided 27 points against the Milwaukee Bucks on March 10.

Milwaukee’s defense has been dreadful over the last 10 games, surrendering the fifth-most points (120.5), most three-pointers (16.9) and third-highest three-point percentage (39%), while sporting the 29th-ranked defensive rating (123.3).

Booker should be motivated to get his team back on track after four straight losses, and I expect him to take advantage of this highly-favorable matchup at home.

Bucks vs Suns same-game parlay

The Phoenix Suns are back home after a six-game road trip, and they'll be fired up after losing to the San Antonio Spurs on a Victor Wembanyama buzzer-beater in their last game out.

Phoenix won 129-114 against the Milwaukee Bucks at Fiserv Forum, and they can cover Saturday's big spread against an opponent missing its superstar forward and a number of key role players.

The Suns should have no problem finding their groove offensively. Even if the Bucks have trouble scoring, Phoenix should put up more than enough points to nudge this line to the Over.

Milwaukee's 29th-ranked defense will have no answers for Devin Booker, Jalen Green and Co.

Our "from downtown" SGP: Suns shine bright

Jalen Green has averaged 23.9 points across his last eight games. After scoring 23+ in five straight, he’s gone Under that point total in each of his last three games. He scored 25 against the Bucks on March 10, and I look for him to get back on track in the scoring department.

Collin Gillespie has hit the Over on this combo line in two straight and five of his last eight. He posted 30 PRA in his first matchup with the Bucks.

Oso Ighodaro will get another starting nod with Mark Williams sidelined. He’s gone for at least 22 PRA in two straight and four of his last 10.
