Walter Walker recorded his fifth consecutive first-round submission victory at UFC Abu Dhabi, this time defeating Thomas Petersen with a calf slicer — a rarely used technique previously landed by only two other men in UFC history, Charles Oliveira and Brett Jones. The win ties Walker with Demian Maia for the most consecutive submission victories in the modern UFC era and equals Rusimar Palhares' record for most leg-lock wins in the promotion. Walker controlled Petersen from his back after dragging him to the canvas from a clinch, executing the submission even as his opponent attempted to crawl to safety.
Walter Walker cemented his place in UFC history on Friday at UFC Abu Dhabi, submitting Thomas Petersen with a calf slicer to record his fifth consecutive first-round submission victory and tie the modern-era record for most consecutive submission wins in the promotion.
The calf slicer itself is a genuine rarity at the highest level of mixed martial arts. Only two other fighters — Charles Oliveira and Brett Jones — have ever landed the technique inside the UFC's Octagon. Walker's use of it here also ties Rusimar Palhares' record for the most leg-lock victories in UFC history, an accomplishment that underlines the uncommon depth of his submission arsenal. The win draws him level with Demian Maia for the longest consecutive submission winning streak in the modern UFC era — a record previously considered untouchable given Maia's legendary grappling pedigree.
Petersen, a 31-year-old American competing out of Spartan MMA, entered the fight with an 11-4 professional record and a reputation as a physically capable opponent. Standing six-foot-one with a 74-inch reach, he carries meaningful offensive output — averaging 3.1 significant strikes landed per minute at a sharp 59 percent accuracy — and generates a solid 3.01 takedowns per 15 minutes of his own. On paper, his wrestling credentials made him a credible test for any submission specialist. In practice, Walker dragged him to the canvas from a clinch, controlled him from his back, and locked in the calf slicer even as Petersen attempted to crawl toward the cage fence in search of an escape.
Why it matters
- Five straight first-round submission wins ties Walker with Demian Maia for the longest such streak in modern UFC history
- The calf slicer finish is only the third ever recorded in UFC competition, joining efforts from Oliveira and Jones
- Walker also equals Palhares' all-time UFC leg-lock record, signaling a potential generational shift in lower-body submission grappling at the elite level
- Petersen's solid wrestling background made the dominant performance all the more striking for divisional observers
