The result
Ryan Gandra def. Ozzy Diaz — KO/TKO (punches), R1 2:04
Ryan Gandra extended his winning streak to ten straight, stopping Ozzy Diaz with punches just over two minutes into round one.
Gandra stormed forward with a salvo of strikes and once he began landing clean, Diaz was slumped against the cage and the referee stepped in, running his UFC record to 3-0 with all three wins by stoppage.
The breakdown below was written before the fight.
The read
Gandra's nine-fight win streak and finishing instincts make him the man with momentum, but Diaz has the power to end any fight in a single exchange, as his own career has shown on both sides of the ledger.
If Gandra can use his wrestling and volume to control range, his streak should continue; if this turns into a firefight, Diaz's history says it ends early either way.
The matchup
This pairs an explosive finisher unbeaten in nine straight against a veteran former regional champion who has never lost any way but by strikes.
Gandra's finishing rate and four straight first-round stoppages make him a live threat from the opening bell, while Diaz's own knockout power means a firefight favors neither man's chin.
