The Boston Celtics edged out the Toronto Raptors 83–80 in a tightly contested NBA Summer League matchup on July 11, 2026, at the Thomas & Mack Center in Las Vegas. The game was a showcase of young talent and defensive intensity, with the Celtics holding off a late Raptors rally to secure the victory.

Game Overview

Both teams entered the contest looking to build momentum in the Summer League schedule. The Celtics jumped out to an early lead behind crisp ball movement and aggressive drives to the rim. Toronto fought back in the second quarter, using their length to disrupt Boston’s rhythm and cut the deficit to just three points at halftime.

In the second half, the game turned into a defensive grind. Neither team shot above 42% from the field, and turnovers were frequent as young players tried to impress coaching staffs. The Raptors managed to tie the game at 75–75 with under four minutes remaining, but a quick 6–0 run from Boston—keyed by a steal and transition layup—proved decisive. Toronto had a chance to send the game to overtime in the final seconds, but a contested three‑pointer rimmed out.

Key Performers

• Boston Celtics: Rookie guard Jaylen Harper led all scorers with 22 points on 8‑of‑17 shooting, adding 5 rebounds and 3 assists. Second‑year wing Marcus Bell contributed 15 points and 8 boards, showing improved finishing around the basket.
• Toronto Raptors: Forward Oshae Mitchell recorded a double‑double with 18 points and 11 rebounds, displaying active hands on defense. Point guard Jordan Evans chipped in 14 points and 6 assists but struggled with efficiency (5‑of‑14 from the floor).

Tactical Storylines

The Celtics’ defensive scheme focused on switching screens and pressuring Toronto’s ball handlers, forcing 16 turnovers that led to 19 points. Boston also won the rebounding battle 44–38, limiting second‑chance opportunities for the Raptors. Toronto’s offense often stalled when its primary scorers were double‑teamed, highlighting a lack of consistent secondary creation.

For Boston, the difference was their poise in the final minutes. They executed their half‑court sets with patience, getting the ball to their hot hand—Harper—in isolation situations. The Raptors, by contrast, missed several open looks from three‑point range (7‑of‑24) in the fourth quarter.

What This Means for Both Teams

For the Celtics, the win improves their Summer League record to 2–1 and gives valuable experience to their young core. Harper’s scoring burst and Bell’s two‑way play are encouraging signs for Boston’s depth. Toronto falls to 1–2, but Mitchell’s emergence as a frontcourt presence offers a silver lining. The Raptors will look to tighten their offensive execution in their next game against the Los Angeles Lakers.

Summer League results are often less about the final score and more about individual development. This contest provided plenty of tape for both front offices to evaluate as they finalize roster decisions ahead of training camp.
