Maestro, magician, enigma, visionary, ringmaster.

Rajon Rondo is hard to describe.

Con artist, contortionist, inventor, aviator.

But delectable to watch.

Rondo plays basketball the way jazzmen make music.

He improvises. He links unpredictable moves together like Thelonious Monk linked unorthodox notes together, creating a string of pearls. He ventures off on solos but always comes back to harmonize with his bandmates.

The Miami Heat could not silence Rondo’s virtuoso performance in the first half of Wednesday’s Game 2 of the Eastern Conference finals. They used canny defensive methods to prevent him from soaring for most of the second. But Rondo led Boston into overtime and his remarkable riffs kept things suspenseful to the very end of Miami’s 115-111 victory.

Rondo, Boston’s sublime point guard, finished with a career high of 44 points, and added 10 assists and eight rebounds. It was a combination never before tallied in an NBA playoff game.

He scored all 12 of Boston’s points in overtime.

He played every second of a game full of dizzying reversals.

When the Heat was sighing with relief and AmericanAirlines Arena spectators were heading for the aisles, Rondo swished two three-pointers to keep alive Boston’s hopes of stealing one game in Miami.

With Rondo at the wheel Boston’s Big Three did not look like the “aging Celtics.”

He found his creases, his tunnels and fifth-dimension planes. He found his teammates’ sweet spots that had been shut off in Game 1.

He defended LeBron James on the last-second jump shot in regulation that bonked off the glass, sending the game into overtime.

He juked past James and sped by Dwyane Wade for a two-point lead early in overtime, then sank a long jumper and two free throws – and should have been allotted two more free throws after getting swiped in the head by Wade.

“That was a big swing for us,” Rondo said of his missed reverse layup with Wade on him and the score tied at 105. “Just didn’t go our way.”

He tried to compensate for the absence of Paul Pierce, who fouled out.

He almost did, sinking four of five shots.

“It’s irrelevant,” an unsmiling Rondo said afterward. “We lost.”

In the end, Rondo’s marathon effort was not quite enough. The Heat will take a 2-0 series lead to Boston for Friday’s Game 3.

The Heat knew Mondo Rondo would be their primary matchup problem against Boston. Love him or hate him, Miami fans got a treat Wednesday – Rondo at his best.

For much of the game, the Heat had no solution for him. Guard him too close and he slithers right past you. Guard him too far and he has room to pass or shoot.

He mixed his usual acrobatic drives with a surprising array of jump shots and those uncharacteristic three-pointers.

“He has to keep doing that,” Celtics coach Doc Rivers said of Rondo. “We have to get more guys involved as well. We had a lot of empty possessions. There are things we can fix, and we will.”

Rondo took a kick-out pass from Pierce and hit a pivotal jumper to extend Boston’s lead to five and stall Miami’s comeback with less than five minutes to play.

After Udonis Haslem’s baseline jumper capped a 9-0 run that put Miami ahead 98-94, Rondo countered with an assist to Kevin Garnett, and Ray Allen nailed a three-pointer to tie with 34.3 seconds left.
