Opponent: Francisco PradounanimousR3 5:00
UFC 327
11 Apr 2026

Radtke beat Prado by unanimous decision in Miami and steadied himself after the Mike Malott loss from the spring. The result mattered because it gave him wins in four of his last six UFC appearances and kept his move through the welterweight roster on track.

Key moments

  • Won a unanimous decision over Prado after three rounds at UFC 327.
  • The victory followed his third-round rear-naked-choke finish of Daniel Frunza in November 2025.
  • It moved his professional record to 12-5.

Opponent: Daniel Frunzarear-naked chokeR3 4:29
UFC Fight Night: Garcia vs. Onama
1 Nov 2025

Radtke worked through a longer fight with Frunza and found the rear-naked choke late in round three at the Apex. It was an important rebound because he had been stopped by Malott six months earlier and needed a composed finish rather than a frantic firefight.

Key moments

  • Submitted Frunza at 4:29 of the third round.
  • The finish snapped the one-fight skid from UFC 315.
  • It set up the April 2026 matchup with Francisco Prado.

UFC 315: Muhammad vs. Della Maddalena
10 May 2025

Radtke was caught early in the second round by Malott in Montreal and lost by knockout inside half a minute of the frame. The setback mattered because he had built real momentum off consecutive UFC wins and was trying to break into the division's next tier.

Key moments

  • Lost to Malott by punches at 0:26 of round two.
  • The defeat interrupted a two-fight UFC winning streak.
  • Radtke returned with a submission win over Daniel Frunza later in 2025.
WinTKO
Opponent: Matthew SemelsbergerpunchesR1 0:51
UFC Fight Night: Magny vs. Prates
9 Nov 2024

Radtke blasted Semelsberger out in under a minute and turned what looked like a measured matchup into a statement finish. It was a major follow-up win because it came after the body-shot loss to Carlos Prates and reestablished his aggression as an asset rather than a liability.

Key moments

  • Stopped Semelsberger by punches in 51 seconds.
  • The finish earned him a second UFC win in four appearances.
  • It rebuilt momentum before the Mike Malott booking in May 2025.
LossKO/TKO
Opponent: Carlos Pratesknee to the bodyR1 4:47
UFC on ESPN: Cannonier vs. Imavov
8 Jun 2024

Radtke traded with the dangerous Prates for most of a hard first round before being finished by a knee to the body late in the frame. The loss mattered because it checked the surge created by his wins over Urbina and Mike Mathetha and showed the risk in meeting elite power head-on.

Key moments

  • Was stopped by Prates at 4:47 of the opening round.
  • The finish came after Radtke had won his first two UFC bouts.
  • He answered with the quick Semelsberger stoppage in November 2024.
WinTKO
Opponent: Gilbert UrbinapunchesR1 4:47
UFC Fight Night: Dolidze vs. Imavov
3 Feb 2024

Radtke's second UFC appearance ended in a first-round stoppage of Urbina and gave him a much louder statement than the Mathetha decision. Finishing a fellow UFC-level welterweight that way quickly strengthened the case that his pressure style could carry over from the regional scene.

Key moments

  • Won by first-round TKO.
  • The stoppage came at 4:47 of the opening frame.
  • Moved to 2-0 in the UFC before the Carlos Prates loss.

UFC 293: Adesanya vs. Strickland
9 Sep 2023

Radtke opened his UFC run by beating Mathetha over three rounds in Sydney. The unanimous decision was not flashy, but it mattered because it proved he could handle the step up and bank a disciplined debut win.

Key moments

  • Won his UFC debut by unanimous decision.
  • Completed all three rounds and took the fight on the cards.
  • Started his Octagon tenure with a controlled result rather than a scramble-heavy finish.

CFFC 118: Forest vs. Radtke
1 Apr 2023

Radtke closed his regional run by submitting Forest with a rear-naked choke in the first round at CFFC 118. It was the kind of finishing performance that helped carry him from the regional circuit into the UFC later that year.

Key moments

  • Won by rear-naked choke in round one.
  • The submission came at 4:20 of the opening frame.
  • Served as the final win before his UFC debut.

CFFC 110: Alequin vs. Radtke
14 Jul 2022

Key moments

  • Won by first-round knockout.
  • The finish came at 1:48 of round one.
  • Added another early stoppage during his CFFC stretch.

17 Mar 2022

Radtke edged past Piersma by split decision after three rounds in one of the tighter fights on his ledger. Because the scorecards were divided, the bout stands out as a reminder that he could grind through close regional fights as well as finish them.

Key moments

  • Won a split decision over three rounds.
  • Took one of the narrowest victories on his record.
  • Stayed on track between the Brandon Lopez and Caleb Crump finishes.

  • The finish came at 3:31 of round two.
  • Bounced back immediately after the Montalvo setback.

  • Added a higher-level learning fight to his early resume.

10 Mar 2018

Hubbard outpointed Radtke over three rounds in one of the stronger names on Radtke's pre-UFC resume. Although it went down as a clear loss, the fight still sits as an early measuring-stick bout against someone who later built a UFC run of his own.

Key moments

  • Lost a unanimous decision over three rounds.
  • Faced one of the more recognizable opponents from his regional years.
  • Used the setback as part of the longer path toward later consistency.

  • Added another finish to his early professional record.

Radtke's first recorded pro win came by triangle choke against Jimmy Kim in the opening round back in 2012. The result opened the record with a submission, even though much of his later reputation was built on pressure striking and knockout power.

Key moments

  • Won by triangle choke in round one.
  • The submission came at 2:07 of the opening frame.
  • Logged the first victory listed on his professional record.

The Read

Style, strengths, and where this fighter stands.

Radtke is a compact pressure welterweight whose best rounds come when he can turn calm opponents into pocket fights. He is willing to force exchanges early, mix in level changes behind his boxing, and trust the durability and top control that carried him through the regional scene before he reached the UFC.

The recent run shows both the upside and the risk in that style. Radtke opened his UFC tenure with wins over Mike Mathetha and Gilbert Urbina, was checked by Carlos Prates and Mike Malott when the firefights turned against him, then rebounded with the fast Semelsberger stoppage, the late Frunza choke, and a clear decision over Francisco Prado at UFC 327.
