The bad: Derrick White attempted 10 3-pointers in Tuesday’s matchup with the Jazz and made just two of them.

The good: just about everything else about the Celtics guard’s latest outing.

White finished with 27 points, seven rebounds, six assists and a staggering seven blocks as Boston beat Utah 129-119 at the Delta Center. He became first guard in NBA history to post those numbers in a single game, with his career-high seven rejections tying the recorded NBA record for his position.

The league’s premier backcourt shot-blocker was perfect from 2-point range (6-for-6) and from the foul line (9-for-9), and he scored 22 of his points in the second half.

Teammate Jaylen Brown could not extend his streak of nine consecutive 30-point games — tied with Larry Bird for the longest in franchise history — but he was productive nonetheless, scoring 23 with 10 assists, six rebounds and two steals.

Anfernee Simons added 20-5-4 off the bench in one of his best all-around games as a Celtic, and Payton Pritchard finished with 18. Like White, Pritchard struggled from deep (1-for-7) but was 7-for-8 from 2-point range.

Utah got big games from Keyonte George (37 points, seven assists, six rebounds) and Jusuf Nurkic (26-8-8), who both were instrumental in the Jazz’s last-second win at TD Garden on Nov. 3. But the Celtics pulled ahead late in the third quarter and never trailed in the fourth.

The Celtics will continue their season-long five-game road trip Thursday in Sacramento, where they’ll face the Kings on New Year’s Day (10 p.m. ET).

Boston fell behind by double digits in the first quarter for the third time in four games. During one especially messy sequence for the slow-starting Celtics, George went down beneath the basket with an apparent injury, and the C’s failed to capitalize on consecutive 5-on-4 possessions.

Both of those actually ended in fast-break buckets for Utah’s Lauri Markkanen, triggering a timeout from a frustrated Joe Mazzulla. George also remained in the game and scored 15 of the Jazz’s 38 first-quarter points.

The Celtics recovered after that stoppage, boosted by the insertion of Luka Garza. Cast out for much of December, the backup center has been consistently productive since rejoining Mazzulla’s rotation last weekend. He scored eight points in five first-quarter minutes against Utah, hitting a 3-pointer and converting two shots at the rim off well-timed feeds from Brown, the second of which drew a foul.

Another Garza triple capped an 18-2 Celtics run that stretched into the second quarter and put Boston ahead 49-40. Fellow reserves Simons, Sam Hauser and Hugo Gonzalez also made threes during that rally, with Gonzalez banking his in off the backboard.

Garza finished with 15 points on 6-of-8 shooting, six rebounds, one steal and one block in the win. He was a plus-13 in his 19 minutes, second-best on the team behind Simons’ plus-26. Both have been plus/minus and net rating darlings of late.

Boston’s starters, however, initially struggled to maintain that momentum.

Brown, White and Pritchard all shot the ball poorly in the first half, going a combined 7-for-23 and 2-for-12 from beyond the arc. At the other end, George stayed piping hot. The 22-year-old poured in 23 first-half points — including a spinning, off-balance, in-the-corner 3-pointer over tight coverage from White — to fuel a 22-5 Jazz response.  Utah led 64-59 at half.

The third quarter was a much stronger offensive display from the top unit. The Celtics got points on nine of their first 10 possessions of the second half, with every starter scoring at least once during that stretch. Pritchard totaled nine points in the quarter, working the midrange as he has so effectively this season, and White hit a go-ahead straightaway 3-pointer to snap an 0-for-7 start from deep.

Brown created White’s wide-open look by drawing three Jazz defenders on a drive and kicking the ball out to his veteran teammate. He also assisted on both of Simons’ third-quarter 3-pointers, which helped power a 9-0 Celtics run. By the time the quarter ended, Brown already had compiled his second-highest assist total of the season.

The Celtics closed the third with a flourish. Gonzalez botched a rebound under the Utah basket but redeemed himself by immediately drawing a charge. Moments later, Simons raced for a 2-for-1 layup, and Brown followed with a steal and a finish to put Boston up 99-96 heading into the fourth.

A string of Celtics fouls put Utah in the bonus with 8:34 left in regulation, but White kept Boston in command. With Brown on the bench, the reliable guard scored 11 points in six minutes and blocked his sixth shot of the night. He added his seventh in the final minutes.

Only San Antonio Spurs superstar Victor Wembanyama, who is at least a foot taller than the 6-foot-4 White in any game this season.

Brown checked back in with 5:21 to play and buried three tough midrange jumpers — including one over the 7-foot-1 Markkanen — to put the game away.
