Introduction

UFC Fight Night 151: Iaquinta vs. Cowboy took place on Saturday, May 4, 2019 at Canadian Tire Centre in Ottawa, Ontario, Canada — broadcast live on ESPN+ as ESPN+ 9.

The main event was a lightweight bout between Al Iaquinta and Donald Cerrone.

Cerrone defeated Iaquinta by unanimous decision (49-45x2, 49-46) in a dominant five-round performance built on leg kicks and technical counter-striking, including two knockdowns. Cerrone earned Fight of the Night alongside Iaquinta. Walt Harris earned Performance of the Night for a 50-second HW TKO of Sergey Spivak.

Second UFC in Ottawa — Cerrone’s McGregor Audition

Canadian Tire Centre holds approximately 19,000. The 10,960 attendance and $807,000 gate were solid for Ottawa’s second UFC visit. Cerrone’s pre-fight positioning was explicitly about the Conor McGregor commercial opportunity: he had been publicly lobbying for the McGregor fight after his Nashville FotN TKO of Alexander Hernandez, and media coverage framed the Ottawa main event as his audition performance. A dominant win over Iaquinta — a top-ranked LW who had previously taken Khabib Nurmagomedov to five rounds — was the required result to maintain McGregor credibility.

Iaquinta was 14-3-1 professionally entering Ottawa, with his only UFC losses being to Kevin Lee (by TKO) and Khabib Nurmagomedov (by UD in the interim title fight at UFC 223). His reputation as a durable, competitive LW whose chin and output were elite-level was the commercial foundation for Cerrone’s dominance to be assessed against.

Main Event: Cerrone’s Leg Kick Masterclass Over Iaquinta

Cerrone’s tactical foundation was leg kick volume and accuracy. The ESPN strike data showed 34/34 leg kick attempts landed — effectively 100% connection rate on his leg kick attempts across five rounds. Iaquinta’s lead leg absorbed the cumulative damage from Cerrone’s patient, consistent kick targeting throughout the first three rounds. The knockdowns — two separate instances across the five rounds — produced 10-8 rounds that inflated the margins beyond what pure strike accumulation would have suggested.

The 49-45 scorecards reflected a fight where Cerrone won at least four of five rounds. His 140/363 total strike attempts versus Iaquinta’s 90/223 showed the output gap that five rounds of leg kick accumulation and head-strike counter-punching produced. Post-fight, Cerrone stated that the Ottawa win was his statement to the UFC and to McGregor: the commercial matchup he wanted was legitimized by the dominant individual performance.

Harris’ 50-Second HW PoN, Chiasson’s 3rd Finish PoN & The Card

Walt Harris’ 50-second TKO of Sergey Spivak with knees and punches was the Ottawa card’s fastest individual finish. Harris’ head kick and follow-up KO sequence at 0:50 of round one earned him Performance of the Night and demonstrated the HW power that his subsequent career amplified. Spivak was a 23-year-old Moldovan HW making early UFC appearances; Harris’ finish of him was decisive. Macy Chiasson’s TKO of Sarah Moras at 2:22 of round two was her third consecutive UFC finish — following her Colorado debut TKO at FN139 and her Nashville TKO at FN148.

Shane Burgos’ split decision over Cub Swanson was a significant FW result: Swanson had been one of the division’s most experienced fighters, and Burgos’ continued output across three rounds — despite Swanson’s experience advantage — produced the 30-27, 29-28 majority for Burgos. Merab Dvalishvili’s 30-27 across all three judges over Brad Katona continued his BW win streak after the back-and-forth career that had included the Simon guillotine loss at FN128 and the Moscow bounce-back. Derek Brunson’s comprehensive decision over Elias Theodorou produced the MW co-main result before a Canadian crowd that had hoped for Theodorou’s win.

Legacy & Impact

Cerrone’s Ottawa dominant win over Iaquinta produced the McGregor fight at UFC 246 in January 2020 — and one of McGregor’s fastest career stoppages, as McGregor TKO’d Cerrone in 40 seconds with shoulder strikes and a follow-up TKO. Cerrone’s Ottawa performance was the competitive foundation that made the McGregor matchup commercially logical: a dominant 49-45 UD over a top-five LW demonstrated his continued elite LW competitive quality.

Dvalishvili’s Ottawa win over Katona was another step in the UFC BW career build that produced a remarkable 12-fight UFC win streak through 2023, making him the BW division’s most active winning contender. Burgos’ Ottawa win over Swanson established him as a top-ten FW with multiple additional ranked wins to follow. Walt Harris’ Ottawa 50-second PoN was a preview of the HW power that produced additional UFC PoN finishes in subsequent years.

FAQ

What was Cerrone’s leg kick rate?

The ESPN fight center data showed Cerrone landing 34 of 34 leg kick attempts — a near-100% connection rate across five rounds. Leg kicks are typically successful between 50-70% of the time in elite MMA competition; Cerrone’s Ottawa leg kick connection rate was one of the most precise individual kick targeting performances in the UFC’s LW division’s history. The accumulated damage to Iaquinta’s lead leg produced the movement compromises that created the knockdown opportunities in later rounds.

What was Iaquinta’s LW standing before Ottawa?

Iaquinta had gone 5-1-1 in his previous seven UFC fights, with his only loss being a TKO to Kevin Lee and his most notable fight being the five-round UD loss to Khabib Nurmagomedov at UFC 223 in April 2018, where he had been the late-notice replacement interim LW title fight. His Khabib performance — surviving five rounds against the division’s most dominant fighter — established him as a top-five LW with elite chin durability. Cerrone’s 49-45 UD over him in Ottawa was assessed against that competitive foundation.

What was Macy Chiasson’s consecutive finish record?

Chiasson’s Ottawa TKO of Moras was her third consecutive UFC finish: a first-round TKO at UFC FN139 in Denver (her debut), a second-round TKO at UFC FN148 in Nashville (of JJ Aldrich), and now a second-round TKO in Ottawa. Three consecutive UFC finishes in a debut period was a commercially significant individual record that the UFC highlighted in her profile building. Her physical LHW-turned-BW size and forward-pressure style produced the finishing output that differentiated her from decision-heavy BW division fighters.

What was Merab Dvalishvili’s competitive context?

Dvalishvili was a 28-year-old Tbilisi, Georgia bantamweight who had gone 5-3 in the UFC before Ottawa, with his losses including the Simon guillotine at FN128 and the Moscow bounce-back win. His Ottawa 30-27 decision over Katona — comprehensive across all three rounds — was the beginning of the consistent competitive quality that produced his remarkable 12-fight UFC win streak from 2019 through 2023. His wrestling-volume style was the most dominant BW game plan of his era.

What was Shane Burgos’ career significance after Ottawa?

Burgos was a 26-year-old New York City featherweight who had gone 11-1 professionally before Ottawa. His Ottawa split decision over Swanson — a fight that produced a 30-27 from one judge for Burgos despite Swanson’s experience — demonstrated the output volume and pressure style that his subsequent FW career built upon. His subsequent wins over Makwan Amirkhani, Josh Emmett, and Calvin Kattar before a loss to Charles Jourdain established him as a top-ten FW fixture.

What was Arjan Bhullar’s Ottawa significance?

Bhullar was a 31-year-old Surrey, British Columbia HW of Indian Sikh heritage — the first fighter of Indian descent to fight in the UFC. His Ottawa decision over Juan Adams before a Canadian crowd was a locally resonant individual competitive result. His subsequent UFC HW career produced additional wins before his departure from the UFC and signing with ONE Championship, where he won the ONE HW Championship in May 2021 — becoming the first Indian MMA world champion in major promotion history.
