Sean Sharaf vs Steven Asplund Fight Analysis

Introduction

The preliminary card of UFC Fight Night: Royval vs Kape on December 13, 2025, promises to deliver high-octane action from the UFC APEX in Las Vegas, Nevada, and one of the most intriguing matchups on the docket is the heavyweight collision between Steven Asplund and Sean Sharaf. Pacing the canvas under the bright lights of the APEX, this bout is set to take place on Sunday, December 14, 2025, kicking off a stacked slate of undercard contests that could impact the trajectory of both men’s UFC careers.

Fighting at heavyweight (206 – 265 lb), Steven Asplund (1–0–0) enters as the -265 betting favorite with BetOnline.ag, reflecting strong early money and confidence in his skillset despite having just one professional outing under the UFC banner. The 27-year-old from Edina, Minnesota, made an emphatic Octagon debut on December 2, 2025, showcasing his crisp striking and defensive acumen. Asplund boasts a 65% significant strike accuracy and an impressive 71% significant strike defense, attributes that underscore his technical prowess and ability to neutralize incoming punishment. At 6'5" with a 78" reach, he has the physical dimensions to keep opponents at bay and capitalize on counter-striking opportunities.

On the other side of the octagon stands Sean Sharaf (4–1–0), the +225 underdog, who has quickly carved out a reputation as a thunderous finisher in the heavyweight division. The 32-year-old Anaheim native has racked up four knockout victories, all in the first round, and averages a swift 7:15 fight time, indicating a penchant for early aggression and one-punch power. Despite suffering his lone UFC defeat via second-round TKO to Junior Tafa in October 2024, Sharaf’s pedigree as a freestyle fighter with explosive hand speed and knockout artistry makes him a dangerous wildcard.

While Asplund’s measured, technical approach and undefeated UFC record point to a methodical dismantling, Sharaf’s knockout résumé and willingness to press forward add a thrilling “live underdog” dynamic. Oddsmakers and fans alike will be keen to see if Asplund can impose his jab-and-move strategy or if Sharaf’s power punches will spell an upset.

Head-to-Head Comparison

| Attribute | Steven Asplund | Sean Sharaf | |---------------------------|---------------------------|---------------------------| | Record | 1–0–0 | 4–1–0 | | Significant Strike ACC | 65% | 45% | | Significant Strike DEF | 71% | 45% | | Takedown ACC / DEF | 0% / 0% | 13% / 0% | | Knockout Power | Low | High | | Early Finish Rate | 0% | 100% | | Average Fight Time | 16:00 | 7:15 |

This clash represents a classic striker-versus-power-puncher duel. Asplund aims to keep the fight at distance, picking apart Sharaf with jabs and leg kicks, draining his gas tank and negating his power. Sharaf, conversely, will look to cut off the cage quickly, close distance, and land heavy hooks or uppercuts before Asplund can establish rhythm. The winner will be the fighter who imposes their will—technical precision or raw violence—over the contested center of the Octagon.

What It All Means

• Value on the Favorite: Asplund’s line shortening indicates respect for his technical superiority, but at –265 you’re risking more for a smaller return.
• Underdog Upside: Sharaf’s +225 line offers a lucrative payout if his knockout power pays off—but with a market-implied 30% win rate, it’s a higher-risk, higher-reward play.
• Line Stability: With only minor shifts so far, the fight’s narrative remains intact: the odds favor Asplund controlling range and pace, while Sharaf must land big early to justify backing him.

Whether you lean on the favorite’s polished game or gamble on the underdog’s one-punch explosiveness, understanding these odds and their subtle movements is crucial for finding the best edge ahead of fight night.
