BetCity Fight Nights 138 will feature two welterweight Grand Prix bouts when the promotion heads to Saint Petersburg on June 6, with promoter Kamil Gadzhiev confirming Andrey Koreshkov versus Gleison Tibau and Sergey Romanov versus Andre Muniz as part of the tournament field.
Koreshkov, nicknamed "Spartan," carries an impressive 19-2-0 record into the matchup at 35 years old. The six-foot welterweight is a high-volume striker who lands 2.84 significant strikes per minute at 39 percent accuracy, and he also poses a consistent grappling threat with 4.8 takedowns per 15 minutes. Notably, he has never recorded a submission attempt, suggesting his ground work is focused entirely on control rather than finishing.
His opponent, Tibau, is a 42-year-old Brazilian veteran out of American Top Team who owns a 33-14-0 record accumulated over a long career. Standing five-foot-ten with a 71-inch reach, the southpaw is one of the more decorated grapplers in the field, averaging 4.08 takedowns per 15 minutes. His striking output sits at 1.95 significant strikes per minute, though his 31 percent accuracy indicates he relies more heavily on the wrestling game.
In the second Grand Prix contest, Romanov meets Andre Muniz, the 36-year-old Brazilian southpaw known as "Sergipano." Muniz brings a 24-8-0 record and stands six-foot-one with a long 78-inch reach. He is a well-rounded threat, landing 2.08 significant strikes per minute at a sharp 48 percent accuracy while also averaging nearly four takedowns per 15 minutes and 1.1 submission attempts per 15 minutes.
Why it matters
- Both bouts count toward BetCity Fight Nights' welterweight Grand Prix, meaning tournament advancement is on the line for all four competitors
- Koreshkov and Tibau represent contrasting grappling profiles — high takedown volume on both sides but with different finishing instincts
- Muniz's submission threat combined with his reach advantage sets up an intriguing stylistic puzzle for Romanov
