LAS VEGAS — The Celtics closed out their 10th day in Las Vegas with a 103-98 loss to the 76ers, finishing the Summer League with a 2-3 record.

Drew Peterson, who sat out the last two games, was back in the starting lineup, along with Jordan Walsh, Baylor Scheierman, Anton Watson and Killian Tillie. Jaelen House, Tyler Cook and Tristan Enaruna contributed from the bench.

Walsh came out of a shooting slump and made his first three three-pointers of the night. He finished the game with 18 points on 7-14 shooting. He also had 7 rebounds, 2 blocks and 2 assists, but appeared rushed at times and finished with six turnovers.

JD Davison, Neemias Queta and Jaden Springer, who all saw action and excelled in Summer League earlier, were not included this time around, giving more unsigned players the opportunity to get more minutes.

In their absence, Jaelen House provided a boost off the bench, with 17 points and six assists. House, a tricky guard who went undrafted after attending the University of New Mexico, is also the son of former Celtic and current NBC analyst Eddie House. He has appeared in the last two Summer League games and could be an interesting addition in Maine.

Tyler Cook, who went to high school with Jayson Tatum and has played overseas in recent years, had the best +/- for the Celtics, adding 16 points on 5-8 shooting.

Anton Watson continued a solid Summer League campaign with a performance of 15 points, 4 rebounds and 3 assists. DJ MacLeay has already called Watson an NBA-caliber defender and Watson seemed to become more comfortable on offense as the Summer League progressed.

The Celtics led 33-30 after the first quarter and 52-49 at halftime, but were outscored 34-21 in the third quarter and trailed by 10 points entering the final period.

A late push led by Baylor Scheierman, who had eight points in the fourth quarter, made it a one-possession game, but both Scheierman and Walsh missed potential game-tying three-pointers in the final minute.

Scheierman started 0-7 from the field, but made two 3-pointers in the fourth quarter to cut the deficit to three and put himself in position to tie it. He finished with 13 points, 7 rebounds and 4 assists. Peterson, who recently re-signed with the Celtics on a two-way, added 6 points, 3 rebounds and 3 assists and was tasked with ball-handling duties when House was benched.

For the 76ers, David Jones led the way, with 23 points (9-15 FG) and eight rebounds. Judah Mintz added 18 points and four steals, while Jordan Tucker provided a spark off the bench, finishing with 19 points on 7-10 shooting. Jared McCain, who was drafted 16th overall last month, finished with 15 points in 16 minutes.
