The 30-second version
- ✓Zepeda won clear — 117-111 twice and 118-110 — on the volume that has always defined him.
- ✓It answered the exact question the preview posed: could craft solve a man who never stops punching? Not this night.
- ✓Zepeda's first world title, and redemption a year after his lone loss to Shakur Stevenson.
- ✓Muratalla stayed unbeaten and kept his IBF belt over Conceição — the co-feature delivered too.
- ✓The lesson: output is a skill you bank in the gym. Roach was sharper; Zepeda was simply there more often.
● The short answer
William Zepeda beat Lamont Roach Jr. by unanimous decision (117-111, 117-111, 118-110) at the Theater at Virgin Hotels in Las Vegas on August 1, 2026, capturing the vacant WBC lightweight title — a career-best performance and his first major world championship, a year after suffering his only loss to Shakur Stevenson. Zepeda's relentless volume gradually broke down Roach's craft. In the co-feature, unbeaten Raymond Muratalla (25-0) retained his IBF lightweight title against former world champion Robson Conceição, giving the deep 135-pound division two decisive title-night results without a pay-per-view.
We framed the preview as chess versus avalanche: Roach's craft against Zepeda's volume. The avalanche won, and it wasn't close on the cards.
What the fight showed
Zepeda does one thing better than almost anyone at 135: he never stops. The Mexican volume tradition he fights out of isn't about single perfect shots — it's about output that compounds, round after round, until a sharper opponent is simply buried under the sheer count. Roach boxed well in spots, landed the cleaner individual punches, and still lost every scorecard by margins (117-111, 118-110) that tell the real story: he was outworked, not out-skilled.
A year ago Zepeda's relentlessness wasn't quite enough against Shakur Stevenson's defensive genius — his only loss. Against Roach, the same engine that fell short then was the exact tool that won a world title now. Same style, better night, and a belt to show for it.

The co-feature held too
Raymond Muratalla (25-0) did his job against Robson Conceição, retaining the IBF lightweight title and staying unbeaten. Two title fights, two decisive outcomes, one of boxing's deepest divisions — and, as promised, no pay-per-view upcharge.
The training lesson
Here's the uncomfortable truth for every technician: volume is a trainable skill, and it beats craft more often than craft likes to admit. Roach's problem wasn't skill — it was that Zepeda's punch count is built in the gym, months out, through the unglamorous conditioning most fighters skip. Output at that rate for twelve rounds is a physical achievement as much as a tactical one. If your engine can't fund your style, your style loses on the cards.

Craft wins exchanges. Volume wins rounds. The cards only count the second one.
