LAKE BUENA VISTA, Fla. — No need for any big shots this time. Not the way the Toronto Raptors just kept getting stops.

Pascal Siakam had 23 points and 11 rebounds, Kyle Lowry added 22 points and 11 rebounds, and the Raptors evened the Eastern Conference semifinals at two games apiece Saturday night by beating the Boston Celtics, 100-93.

Two days after winning Game 3 on OG Anunoby’s 3-pointer as time expired, the Raptors shut down most of Boston’s perimeter shooters, and Jaylen Brown in particular.

Serge Ibaka had 18 points off the bench on 7-of-9 shooting and Fred VanVleet finished with 17 points, six rebounds and six assists. The Raptors shot only 39.5% but believe they’ll eventually put their offense and defense together on the same night.

“I think we can always get to another level. I feel like we can always do that and obviously everyone clicking at the right time, and once we have that, we’re a pretty special team,” Siakam said.

Jayson Tatum led the Celtics with 24 points and 10 rebounds. They won their first six postseason games before dropping the last two. Kemba Walker had 15 points and eight assists.

“Obviously, we didn’t play that well, I didn’t play that well,” Brown said. “We’ve got to bounce back and be ready to fight. That’s what it comes down to.”

The Celtics were 7 for 35 (20%) from 3-point range. Brown missed his first nine attempts behind the arc before making two late in the game, and finished 4 for 18 overall. Tatum, Walker and Marcus Smart were all 1 for 6 on 3-pointers.

“I think we made it a little bit tougher for them tonight, but they still had a lot of shots that they were able to get off,” Lowry said. “We’re just trying to contain those guys: Tatum, Brown, Walker, even Smart. We’ve just got to continue to make it tough on those guys.”

The Raptors got their own shooting untracked late in the third quarter to open the first sizable lead by either team, and Boston couldn’t hit nearly enough shots to come back.

Toronto Coach Nick Nurse assumed the Raptors would quickly refocus after the euphoria of their Game 3 victory, and he was right, as Lowry sent them to a quick 11-4 lead with eight points. He scored 11 points in the first quarter, which ended with Toronto leading 31-27.

There were five ties in the second quarter, including when VanVleet’s 3-pointer with 0.9 seconds to go made it 49-all.

After some cold perimeter shooting by both teams, the Raptors finally had a strong stretch late in the third, getting two 3-pointers by VanVleet and another by Ibaka in a little over a minute to open their largest lead at 79-68. Toronto led by eight after three.

The Celtics never got closer than five in the final quarter, and when they did for the final time, Tatum was called for an offensive foul with 32 seconds left.

Walker took only nine shots, a number he said was unacceptable.

“We’ve just got to be better. We’ve got to be tougher. We’ve got to want it more,” Walker said.

TIP-INS

Raptors: When Lowry checked out with 1:31 left in the first quarter, it was his first break in game action since late in the first quarter of Game 3.

Celtics: Boston shot 44% overall. … Brown finished with 14 points and six rebounds.

HAYWARD’S HEALTH

Celtics Coach Brad Stevens said he believed Gordon Hayward, who sprained his right ankle in Game 1 of the first round against Philadelphia, would return to campus Monday. He said Hayward would then have to quarantine for four days, though it will be much longer before he’s ready to return to the lineup.

“But then he’s not going to play anytime soon,” Stevens said.

FAMILY MATTERS

Nurse agreed with Denver Coach Michael Malone’s comments Friday expressing disappointment that coaches aren’t allowed to have guests join them inside the bubble this week, as players did. But he also said he probably wouldn’t have brought his family anyway, and noted that there are other team personnel who can’t bring guests.

“So it’s more than just the coaches that are affected,” Nurse said.
