Victorious in UFC 280 opener
Rosa defeated Lina Lansberg via majority decision (29-27, 29-27, 28-28) at UFC 280 on Saturday in Abu Dhabi.
ANALYSIS
Rosa couldn't defend the takedown in a loss to Sara McMann this past March, so she completely flipped the script in this fight and used her offensive wrestling to secure an easy win. She landed 3-of-6 attempts, good for a whopping 9:44 worth of control time. That's the good news. The bad news is that Rosa was knocked down by Lansberg in Round 1 and docked a point in Round 2 for an illegal knee. Neither ended up having an impact on the final outcome. Rosa has faced mediocre competition over her first half-dozen UFC bouts, but her 5-1 record with the company is impressive nonetheless.

Taking on Lansberg at UFC 280
Rosa will take on Lina Lansberg at the UFC event on Oct. 22, UFC Europe reports.
ANALYSIS
Rosa will look to get back on track after her six-fight winning streak was snapped by a loss to Sara McMann in March. Her opponent, Lansberg, is coming off two consecutive losses, so this will serve as a redemption fight for both contenders.

Can't defend takedown in loss
Rosa lost to Sara McMann via unanimous decision (28-29, 28-29, 28-29) at UFC Fight Night on Saturday in Columbus, Ohio.
ANALYSIS
This fight was nowhere near as close as the final scorecards. It's also a crushing setback to Rosa's hopes of making any sort of impact at 135 pounds. A winner of her first four UFC bouts, all via decision, Rosa was unable to defend the takedown against McMann, which is highly concerning considering her opponent is 41 years of age. Whatever advantage Rosa had on the feet was entirely negated by the fact McMann racked up 10:27 worth of control time. After this performance, it's entirely fair to wonder if Rosa made a name for herself simply by beating up lesser competition. To say she needs a rebound effort her next time out is a massive understatement.

Draws veteran March 26
Rosa will take on Sara McMann in a bantamweight matchup at the UFC event scheduled for March 26, Ag. Fight reports (via Marcel Dorff of MMADNA).
ANALYSIS
Rosa has started her UFC run with four consecutive decision victories and is averaging an impressive 7.88 significant strikes landed per minute over that span, so she's overdue for a step up in competition. That will arrive in the form of a 41-year-old gatekeeper in McMann, who is coming off a loss to current title challenger Julianna Pena in January. McMann has always done her best work on the ground, but Rosa brings a 91 percent takedown defense to the table, albeit over a much smaller sample size. If she can continue to defend well against a top-10 fighter here, there's room for immediate advancement to a high-profile fight in a relatively shallow division.

Sends Bethe Correia into retirement
Rosa defeated Bethe Correia via unanimous decision (30-27, 30-27, 30-26) at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Rosa entered as a -720 favorite, which is retrospect, was far too low. Knowing full well Correia would be unable to damage her on the feet, Rosa continued to push forward to the tune of a 145-85 edge in total strikes landed. It's difficult to remember a single meaningful shot Correia connected with over the course of the entire bout, allowing Rosa to cruise to the easy victory. Rosa has now earned four straight unanimous decision wins (Correia, Joselyne Edwards, Vanessa Melo, Lara Procopio) to begin her UFC run. The Brazilian is still just 26 years of age and a legitimate prospect in a thin division, but we need to see how Rosa fares against better competition before assessing her true potential.
