BOSTON -- Instant reaction after the Memphis Grizzlies trampled the Boston Celtics, 111-91, Wednesday night at the TD Garden:

How the game was won: Grizzlies swingman Rudy Gay poured in a game-high 28 points on 10-of-18 shooting to lead six Grizzlies in double figures in an absolute laugher. Ray Allen and Rajon Rondo chipped in 17 points apiece for Boston, but the Celtics were never competitive from the start.

Turning point: Memphis embarked on a brief 7-0 run 3 1/2 minutes in and never looked back. The Grizzlies led by by 15 after the first quarter and 22 at halftime. The final score hardly reflects their dominance.

Stat of the game: Gay finished with an astounding plus-30 in the plus/minus category, while Hasheem Thabeet -- fresh from a stint in the NBA Development League -- posted a plus-26. That speaks volumes.

Unsung hero: When O.J. Mayo found himself in early foul trouble, Memphis rookie Sam Young (36th overall pick in the 2009 draft) came off the bench to score nine first-quarter point (nearly matching Boston’s 12-point output by himself). Mayo rebounded, too, hitting all but the final of his eight attempts for 17 points.

What it means: The Celtics reached a new low at home this season, dropping to an unfathomable 18-12 at the TD Garden for the 2009-10 campaign. Boston now has as many losses at home as they had combined for here over the past two seasons. With Boston trailing by 25 midway through the fourth quarter, the building basically emptied out. The only noise came from the fans heckling Celtics radio announcer Cedric Maxwell from behind the media section.
