Jandiroba is one of the most dangerous grapplers in the women's strawweight division. Her BJJ credentials translate directly into MMA success, with 1.52 submissions per fight and 2.85 takedowns per fight. She has built her career on dragging opponents to the mat and hunting submissions relentlessly.
Signature Techniques:
Armbar from Multiple Positions - This is her bread and butter. Against Amanda Lemos in July 2024, she secured a second-round armbar after controlling the fight on the ground. Against Felice Herrig, she earned Performance of the Night with a first-round armbar. She sets these up from guard, mount, and during scrambles with excellent timing.
Chain Wrestling to Back Control - Against Yan Xiaonan at UFC 314, Jandiroba landed 9 takedowns and accumulated nearly 10 minutes of control time. In Round 2, she transitioned smoothly to Yan's back, locked in hooks, and peppered her with short strikes while threatening the rear-naked choke. This sequence of takedown-to-back-take is a consistent pattern in her wins.
Clinch-to-Takedown Sequences - Against Marina Rodriguez, Jandiroba used the clinch to neutralize the taller striker's range advantage, then converted clinch positions into takedowns. She pins opponents against the cage, battles for underhooks, and drags them down.
Technical Evolution:
Her recent fights show improved striking setups for her takedowns. Against Yan Xiaonan, she used feints and pressure to close distance rather than shooting naked doubles. She has also become more patient on the feet, picking her spots rather than desperately chasing takedowns.
Striking Defense and Volume - Against Mackenzie Dern at UFC 321, Jandiroba was outlanded 249-208 in total strikes. Dern's jab opened a cut under her right eye in Round 2, and she consistently walked into punches when trying to close distance. Her striking defense percentage sits at 41%, well below elite level.
Inability to Maintain Top Position Against Active Guards - The Dern fight exposed a critical flaw. Despite landing 9 takedowns, Jandiroba repeatedly backed away and let Dern stand up rather than engage on the ground. She absorbed damage from elbows and punches even while in top position. This hesitation cost her the title fight.
Takedown Efficiency - Her 37.5% takedown accuracy means she often needs multiple attempts to get the fight to the ground. Against Yan, she fired off 11 attempts to land 3. Against wrestlers or fighters with solid takedown defense, this volume-dependent approach can leave her exposed to counters during failed shots.
When Her Gameplan Fails:
When Jandiroba cannot secure takedowns, she tends to plod forward and absorb strikes. Against Carla Esparza in her UFC debut, she lost a clear decision when Esparza's wrestling neutralized her grappling. She lacks the striking tools to win rounds on the feet against competent strikers.
Ricci is a pressure fighter who combines clinch work, volume striking, and grinding grappling. She averages 2.69 takedowns per fight and 6.22 strikes landed per minute, showing she can compete in multiple phases.
Signature Techniques:
Clinch Control and Dirty Boxing - Against Angela Hill in August 2024, Ricci repeatedly pinned Hill against the fence, using underhooks to control position while landing knees and short punches. This smothering approach wore Hill down over three rounds.
Elbow Strikes - Her most recent win over Amanda Ribas came via TKO when she landed an elbow that connected with the orbital area. This finishing instinct with elbows gives her a weapon that can end fights unexpectedly.
Pace and Pressure - Against Tecia Pennington, both fighters threw over 100 strikes in Round 1 alone. Ricci's cardio allows her to maintain high output across three rounds, and she uses forward pressure to back opponents against the cage where her clinch work becomes effective.
Technical Evolution:
Ricci has worked with Freddie Roach on her boxing, and her striking has become more refined. Her recent wins show better shot selection and improved ability to mix strikes with takedown threats.
Susceptibility to Elite Grapplers - Against Loopy Godinez, Ricci lost a split decision when Godinez controlled the clinch and prevented her from implementing her gameplan. Her takedown defense ratio of 27% is concerning against a grappler of Jandiroba's caliber.
Striking Defense Under Pressure - Her significant striking defense percentage of 57.8% is decent but not elite. Against Yan Xiaonan, she was clearly outclassed on the feet, absorbing damage throughout all three rounds. When facing superior strikers or grapplers who can dictate range, she struggles.
KO/TKO Vulnerability - Ricci was stopped by Manon Fiorot via TKO in Round 2 of her UFC debut. Fiorot's relentless pressure and aggressive striking overwhelmed her. While this was early in her career, it shows she can be finished when hurt.
When Her Gameplan Fails:
When Ricci cannot establish her clinch work or pressure, she tends to get outpointed at range. Against Yan Xiaonan, she was unable to close distance effectively and lost a clear unanimous decision. She lacks the one-punch power to turn fights around when behind on the scorecards.
This fight presents a clear grappling-versus-grappling dynamic, but Jandiroba holds significant advantages on the mat.
Jandiroba's Techniques That Could Exploit Ricci's Gaps:
Ricci's 27% takedown defense ratio is a glaring weakness against someone who attempts 7.6 takedowns per fight. Jandiroba's chain wrestling sequences, where she transitions from failed shots into clinch work and eventually secures the takedown, should find success here. Once on the ground, Jandiroba's submission threat is far superior. Ricci averages just 0.12 submissions per fight compared to Jandiroba's 1.52.
Ricci's Techniques That Could Cause Problems:
Ricci's clinch work and dirty boxing could disrupt Jandiroba's entries. If Ricci can establish underhooks and control the clinch, she might prevent clean takedowns and land damage in close. Her elbow strikes, which finished Ribas, could be dangerous if Jandiroba shoots carelessly.
Historical Parallels:
Jandiroba's dominant win over Yan Xiaonan provides a template. Yan is a better striker than Ricci and has solid grappling defense, yet Jandiroba controlled her for nearly 10 minutes. Ricci's loss to Godinez, a grappler, suggests she struggles when unable to dictate the clinch.
Early Rounds:
Jandiroba typically starts slow on the feet, feeling out opponents before committing to takedowns. Expect Ricci to push the pace early with pressure and clinch attempts. The key question is whether Jandiroba can time her shots against Ricci's forward movement. If Jandiroba secures an early takedown, she will likely hunt submissions immediately, as she did against Lemos.
Mid-Fight Adjustments:
If Jandiroba establishes her grappling, Ricci will need to show improved takedown defense or risk spending the majority of the fight on her back. Ricci's best chance is to make this a grinding clinch battle where neither fighter can establish dominant positions. However, Jandiroba's experience in these situations, particularly her ability to transition from clinch to takedowns, gives her the edge.
Championship Rounds (if applicable):
This is a three-round fight. Both fighters have shown solid cardio. Jandiroba maintained her pace against Yan for 15 minutes, and Ricci's high-volume style requires good conditioning. If the fight goes deep, Jandiroba's grappling should become more dominant as Ricci tires from defending takedowns.
Grappling Hierarchy: Jandiroba's submission rate (1.52 per fight) dwarfs Ricci's (0.12 per fight). On the ground, this is a mismatch.
Takedown Defense Concern: Ricci's 27% takedown defense against Jandiroba's volume-based approach is a recipe for extended ground control.
Recent Form: Jandiroba is coming off a title fight loss to Dern but won her previous five bouts. Ricci's recent KO of Ribas was impressive, but she lost to Yan before that.
Clinch Battle: Both fighters want the clinch, but for different reasons. Jandiroba uses it to set up takedowns; Ricci uses it for dirty boxing. Jandiroba's ability to convert clinch positions into takedowns should be the difference.
Heuristic Warning: Ricci was KO'd by Fiorot early in her career. While she has improved significantly, the vulnerability to being finished exists.
The SHAP data reveals several factors driving this prediction:
Some factors decreased the score: - Recent Striking Impact Differential decreased by 1.0 - Recent Significant Striking Output Differential decreased by 1.0 - Striking Defense Percentage decreased by 1.0
These negative factors reflect Jandiroba's striking limitations, but the model still favors her grappling advantages.
WolfTicketsAI has a mixed record with both fighters:
Jandiroba: The model correctly predicted her wins over Yan Xiaonan (0.55 score), Amanda Lemos (0.56 score), and Angela Hill (0.72 score). It also correctly predicted her loss to Dern (0.51 score for Dern). However, the model was wrong when it picked Loopy Godinez (0.67) and Marina Rodriguez (0.75) to beat Jandiroba. This suggests the model may undervalue Jandiroba against certain opponents.
Ricci: The model correctly predicted Ricci's loss to Yan Xiaonan (0.64 for Yan), her win over Tecia Pennington (0.53), her loss to Godinez (0.34 for Godinez), and her win over Jessica Penne (0.37). However, it incorrectly picked Amanda Ribas (0.60) to beat Ricci, and Angela Hill (0.61) to beat Ricci. The model has been wrong about Ricci when she pulls off upsets.
This creates some uncertainty. The model has underestimated Ricci before, and it has also underestimated Jandiroba. However, the model's confidence here is moderate (score of 4), which seems appropriate given the competitive nature of this matchup.
Jandiroba's elite grappling should be the deciding factor. Ricci's poor takedown defense and limited submission threat make her vulnerable to Jandiroba's relentless ground attack. While Ricci has shown she can upset the odds, the stylistic matchup heavily favors Jandiroba. Expect the Brazilian to secure takedowns, accumulate control time, and potentially finish with a submission. WolfTicketsAI has Jandiroba winning this fight, and the grappling disparity supports that pick.
