MEMPHIS, Tenn. (AP) — Jerryd Bayless keyed a fourth-quarter rally, scoring all of his 15 points in the period to lead the Memphis Grizzlies to a 95-88 victory over the Boston Celtics on Monday night.

Bayless was 6 of 7 in the quarter to help Memphis erase a six-point Boston lead with just under 9 minutes to play.

Zach Randolph and Mike Conley also had 15 for Memphis, Conley handing out eight assists. Marc Gasol finished with 14 points on 6-of-10 shooting from the field and grabbed eight rebounds.

Jeff Green led the Celtics with 22 points, while Jared Sullinger scored 16, going 2 of 3 from outside the arc. Avery Bradley scored 14 and Jordan Crawford finished with 12.

The Celtics fell to 0-4 under rookie coach Brad Stevens.

Memphis, which struggled at times from the field, finished the night shooting 49 percent, while the Celtics managed 47 percent. The Celtics, who are the worst team in the league at committing turnovers, matched their average with 21, while Memphis wasn’t much better with 19.

Stevens seemed to have a chance at his first NBA victory until Bayless got untracked in the fourth quarter, mostly from around the top of the key. His accuracy led to him playing the entire fourth quarter.

In a matchup featuring teams with two of the highest turnover rates in the league, both reached double figures before the break, the Celtics with 12, Memphis with 10.

The Celtics shot 54 percent in the half and Green scored 16 points for a 50-46 lead. Conley had 11 for Memphis.

The game was close in the first half until the Celtics went on a 10-2 run in the second quarter.

Memphis opened the second half with a 12-4 burst, missing only one of its first nine shots. Meanwhile, Boston hit only one of its nine.

Gasol had 10 early in the third to help the rally that contributed to a 66-57 lead. It didn’t last as Memphis started misfiring, leading to 14 unanswered points for Boston, capped by Sullinger’s 3-pointer.

That gave the Celtics a 72-66 lead heading into the fourth.

Bayless, who was scoreless and had missed all four of his shots in the first three quarters, began connecting from inside the top of the key. Bayless hit his first six shots in the frame to erase the Boston lead on a 3-pointer with 4:19 left. The Celtics never led again.
