Game 2 is on Wednesday in Phoenix.
Booker missed three games during Phoenix's first-round win over the New Orleans Pelicans because of a strained right hamstring suffered in Game 2. He returned for the closeout Game 6 and scored 13 points, but looked a little more cautious than usual in his effort to stay healthy.
That hesitancy was gone in the first quarter on Monday: Booker scored 13 points on 4 of 8 shooting and added six rebounds and four assists.

Ayton dominated in the paint and mid-range, hitting his usual array of turnaround jumpers, runners and dunks. The 6-foot-11 center shot 12 of 20 from the field. Chris Paul added 19 points and Cam Johnson had 17 off the bench.
All five Suns starters scored in double figures.
The Suns' opening salvo was highlighted by a Jae Crowder 3-pointer and Booker's lob pass to Mikal Bridges for a dunk. Phoenix extended its lead to 18-6 midway through the first quarter before a discombobulated Dallas called timeout.
The Mavericks stayed in the game for a while thanks to Doncic and Kleber, who hit his first four 3-pointers. The pair helped Dallas pull within 51-47 midway through the second but the Suns finished the half with another run, going into the break with a 69-56 lead.
Mavs head coach Jason Kidd said they got off to a slow start Monday night but that he likes the way his team responded.
Doncic was slow to get up in the second quarter after taking a knee to the groin from Jae Crowder, who was shooting a 3-pointer and called for the offensive foul.
After an official review, Crowder's foul was upgraded to a Flagrant 1.
Suns backup center JaVale McGee brought the crowd to its feet early in the fourth quarter with a rare defensive play on the perimeter.
He stole the ball from Doncic and then dribbled the length of the floor, finishing with a powerful dunk to put the Suns up 21 points.
