LOS ANGELES ā€” With Paul George out for the second time in a week, the Los Angeles Clippers desperately needed a scoring boost for their showdown with Marcus Smart and the Boston Celtics. Enter Brandon Boston.

Boston, who just turned 20 years of age in late November, came off the Clippers' bench and led the way thanks to a blistering shooting night. The rookie finished with career highs in points (27), steals (4) and 3-pointers (5) in a single game.

ā€œGreat performance,ā€ Clippers head coach Tyronn Lue said of Brandon Boston. ā€œOffensively, we know he can score the basketball and he gave us a big lift, scoring the ball tonight. But like you said defensively, getting some deflections, getting some steals, playing on the backside of the zone and he was huge, getting out in transition. So he played really well.ā€

With Nicolas Batum's return as well as Paul George being a late scratch due to an elbow contusion, the Clippers were forced to start their sixth different starting lineup in the last seven games. Boston didn't start, but came off the bench and provided a much-needed scoring boost.

It's also not like the Celtics weren't prepared for him either.

ā€œWe talked about this kid, specifically him,ā€ Celtics coach Ime Udoka said after the team's loss to the Clippers. ā€œBoston. We talked about him scoring 43 recently in the G League and his minutes have gone up, up, up. Felt like we were surprised by him and we specifically talked about him. Just like I mentioned, KYP, knowing your personnel, know whoā€™s playing. This kidā€™s getting a lot of run, especially with Paul George and some guys out, so thatā€™s disappointing there.ā€

ā€œMr. 46,ā€ as the Celtics players seemed to call him, burned them all night from all areas on the court. The deflections and defense he showed were a bonus from the young Clippers forward.

ā€œI forget what they said, but they were talking crazy before I even caught the ball,ā€ Brandon Boston said. ā€œAs I went up, they say, ā€˜Oh, heā€™s Mr. 46.' Thatā€™s what I heard.ā€

There was even one moment went Brandon Boston scored on Marcus Smart and earned a technical foul for yelling in his direction after.

ā€œI just went at Marcus Smart. You know, got the bucket, and then I just started going at him. Just tell him Iā€™m here, just letting him know that my presence is felt. And that Iā€™m not laying back for nobody.ā€

Dennis Schroder and the Celtics praised the youngster's poise and readiness postgame.

ā€œHe went off,ā€ Schroder said. ā€œCredit to him. I heard he scored 46 points in a G League game. We gotta respect everybody. At the end of the day, he came in and busted our ass. I donā€™t know how many points he had, but over 20. He won them the ball game.ā€

The Clippers will finally have two days off to rest before taking on the Orlando Magic Saturday afternoon at Staples Center. With a practice expected for Friday, it'll give Paul George a few days to rest his elbow ahead of Saturday.
