Everybody had the same flowchart for this fight. Tye Ruotolo, the 23-year-old grappling phenom, needed to get Christian Lee down. Lee, the knockout artist who has finished all but one of his opponents in his past 11 ONE fights, needed to keep it standing and hurt him early. Yahoo Sports summed up the pre-fight consensus: pundits gave Ruotolo a real chance, provided he dragged it into his jiu-jitsu.
Then Ruotolo stood with him, put Lee on the canvas with a combination in the opening minute, poured on ground and pound, took the back and finished a rear-naked choke at 2:08 of Round 1 at Lumpinee Stadium in Bangkok. That’s the ONE lightweight MMA world title (170 pounds under ONE’s weight rules) going to a man who is now 3-0. All three wins are first-round rear-naked chokes. He also took home a $100,000 bonus and still holds the ONE welterweight submission grappling belt, so ONE’s own account posted that he left the night with two world titles.
Both men told us the plan, and only one plan survived
The pre-fight interviews with MMA Fighting read differently now.

Ruotolo had Lee scouted almost exactly. He said he expected Lee to come out with a very high pace, a lot of forward aggression and explosiveness in the first round, throwing big kicks and big punches to end it early, then attacking the legs later if the early blitz didn’t land. He also figured Lee would wait for his chin to come up. Lee, for his part, said he planned to “knock him out cold or put him to sleep,” and he expected Ruotolo to land a strike or a few punches on the way in just to start the grappling.
That last part is the key to the whole fight, in my read. Lee prepared for punches as an entry, meaning shots thrown to close distance and set up a takedown. If you’re defending that, you’re reading the hands as a prelude and your weight is ready to sprawl. What you’re less ready for is a guy whose punches are the actual point. Ruotolo told MMA Fighting the likeliest path was submission, while adding that he had “a lot of cool tools that I’m looking to whip out in the fight as well.” He got to whip them out in the first minute.
I don’t have a frame-by-frame breakdown in front of me, so I won’t pretend to tell you which punch landed. What the reports agree on is the sequence: a combination on the feet, a knockdown that badly hurt Lee, follow-up strikes on the ground, then the back. That sequence is the nightmare version of this matchup for Lee. Once a hurt fighter is on the floor against an elite back-taker, the last line of defense is the very grappling Ruotolo rated at “like a six, a five” before the fight. A five or six with a clear head can survive a lot. A five or six who just got dropped is giving up the back.
Why Lee’s experience didn’t cash in
Lee’s big idea, as he put it to MMA Fighting, was to show Ruotolo the difference between MMA and jiu-jitsu and use his MMA experience against Ruotolo’s grappling experience. That’s a sound concept against a grappler with two pro fights. It assumes the striking exchanges are where the veteran gets paid.

The flaw, as I see it, is that Lee spent camp (with Max Holloway in Hawaii, by his account) preparing for a grappler and then met someone who had clearly drilled the striking enough to win the exchange that mattered. Ruotolo told MMA Fighting the MMA transition left him feeling “like a white belt again in some ways,” learning hand-eye coordination and the other parts that differ from jiu-jitsu. White belts don’t usually drop two-division champions. He’s been honest about the learning curve and fast at climbing it.
There’s also a rust question I’d at least raise. Bloody Elbow pointed out that this was Lee’s first fight in almost a year, and that he hasn’t fought more than once in a calendar year since becoming a double champion in November 2022, when he stopped Kiamrian Abbasov in Round 4 for the welterweight belt. His last outing was a knockout of Alibeg Rasulov to defend at lightweight. Long gaps don’t explain a knockdown, but they don’t help a fighter whose game is built on first-round pace and timing.
And the brother storyline matters here. Ruotolo’s MMA debut, in September 2025, was a rear-naked choke of Adrian Lee. Christian said he helped prepare Adrian for that fight and felt very familiar with Ruotolo’s game as a result. My read is that this familiarity cut the wrong way. Adrian’s fight showed a Ruotolo who took him down very early, as Christian described it. Christian prepared for that version. Fourteen months later, a different version showed up.
What this means at 170
Lee, who is 28, still has the 185-pound belt. Before this fight, the only submission loss on his record was in 2016 to Martin Nguyen, per MMA Fighting. He lost the lightweight title once before, five years ago to Ok Rae Yoon, and came back to reclaim it. So writing him off would be silly.
The awkward part is timing. The day before the fight, Lee told MMA Fighting, “I feel very confident that I’m the best fighter in the world across any organization,” and said he’d want Islam Makhachev for a cross-promotional welterweight fight. Losing in 128 seconds to a 3-0 fighter puts that campaign on ice, and I’d expect the rematch talk to start immediately.

For Ruotolo, this is the plan he described before ever fighting. He told MMA Fighting he asked for a solid opponent in Adrian Lee and doesn’t want a million MMA matches against people he knows he can beat, or, in his words, “I don’t want to fight the taxi cab drivers, you know?” He’s now beaten Adrian Lee, the then 6-0 Shozo Isojima and Christian Lee. Nobody can accuse him of padding.
He also said he wants to defend both belts, mentioning a ONE grappling defense around December or January and the CJI next year on the jiu-jitsu side. Meanwhile his twin, Kade, is 4-0 in MMA with bonuses in three of those wins, per Bloody Elbow. ONE now has two Ruotolos who finish people early under MMA rules, and one of them owns the lightweight strap.
The lightweight division used to have a clear answer at the top. Now the champion is a 23-year-old who walked out of Lumpinee with a grappling belt, an MMA belt and a $100,000 check, and ONE’s first post-fight question on X was simply, “Who’s next?”
