If you tuned in to Floyd Mayweather and Conor McGregor to see absurdity, spectacle and nonsense, you got what you paid for.

What you didn't expect, perhaps? A good fight. And that was a pleasant surprise.

Despite the gimmicky premise of the matchup, MMA champ McGregor acquitted himself well for several rounds on Saturday night at the T-Mobile Arena in Las Vegas, coming out with fire and landing plenty of solid blows against the experienced Mayweather, who is 11 years his senior. It was clear that either "Money" Mayweather was playing with him early, or that the years-long layoff between bouts had taken its toll (he had last fought on May 2, 2015, against Manny Pacquiao).

Whatever the reason, this was a close fight.

But McGregor started to slow down as the rounds trudged on. He dropped his hands, tried to grapple, was warned about hammer punches (blows to the back of the head), and did his best to keep Mayweather at bay before his opponent's skill and precision took over.

By the 10th, McGregor was gassed. A few power shots from Mayweather against a wobbly McGregor was all it took for referee Robert Byrd to stop the fight.

Mayweather: winner by technical knockout. The champ is now 50-0 for his career, besting Rocky Marciano's undefeated mark.

"Rocky Marciano is a legend," Mayweather said afterwards. "And I look forward to going down in the Hall of Fame one day."

There were some kind words exchanged between the foes at center ring, although McGregor said that he thought the ref ended things too early, believing that he was fatigued, not completely beaten: "Let me go down. Let the man put me down."

That said, the majority of viewers who shelled out around $100 to see the proceedings on Showtime pay-per-view had little to complain about. They got a show.

Mayweather played the heel from the jump, entering the arena in a ski mask, while McGregor looked like he belonged in that ring.

The judges at the end scored the 10 rounds in favor of Mayweather, but it was still close.

"I turned him into a Mexican tonight," McGregor said afterward, referring to the frenetic and aggressive fighting style of boxing matches from fighters south of the border (although it was certainly an odd comment, considering some of the racially charged things the loud-mouthed fighter has said in the past). Mayweather did appear to leave his comfort zone for stretches of the bout, advancing forward to attack, rather than his usual defensive posture where he can wear out and wear down an opponent simply by slipping through each swing.

The fans in the arena were certainly pro McGregor, roaring in approval with each punch that the Irishman landed. LeBron James, Alex Rodriguez and James Harden were a few of the familiar faces in the crowd, who paid upwards of $10,000 or more for a seat.

They saw plenty of showmanship from both fighters, especially from the flashy MMA veteran.

That said, McGregor looked the part of a fish out of water, consistently delivering illegal punches to the back of Mayweather's head and awkwardly grappling with the back of his opponent like the two had plans to attend prom after the fight.

That's not to take away from McGregor's effort, which earned praise from analysts Al Bernstein and Paul Maglianaggi on Showtime's pay-per-view broadcast.

And it was far more entertaining than the majority of Mayweather's 49 other wins. You'd even say it lived up to the hype.

So even though Mayweather announced his retirement (again) after it was over, we have to ask the question ... when's the rematch?
