5 most iconic moments of Joanna Jędrzejczyk's UFC career

#4. Joanna Jędrzejczyk demolishes Jessica Penne to retain title – UFC Fight Night 69

Following a dominant title-winning performance in March 2015, Joanna Jędrzejczyk returned to the octagon just three months later to defend her title. In her first title defense, she took on TUF alum Jessica Penne. This was Jędrzejczyk's first time headlining a UFC card.

The duo locked horns in the main event of UFC Berlin.

Jessica Penne put on a stoic front throughout fight week, well aware of the champion's tendency and ability to get under her opponents' skin.

Despite staying fairly composed in the lead-up to the fight, Penne quickly realized that she was no match for Joanna Jędrzejczyk, in what was one of the most one-sided championship bouts in MMA history.

Jędrzejczyk's lightning-quick hand-speed forced Penne to backpedal throughout the fight. The champion's non-stop forward pressure bloodied and battered the challenger, who looked hapless towards the end of the third round. Mercifully, the referee called a halt to the action upon seeing that Penne had nothing more to offer.

The win over Jessica Penne served as a statement-making show of intent in the strawweight division. Joanna Jędrzejczyk's flawless showing led many to believe that the Pole would reign over the 115-pound weight class for a long time to come, and they were right.

#3. Joanna Jędrzejczyk dismantles Jessica Andrade to assert her dominance – UFC 211

After her ruthless display against Jessica Penne, Joanna Jędrzejczyk went on to defend her title against top contender Valérie Létourneau, TUF rival Cláudia Gadelha and fellow Polish strawweight Karolina Kowalkiewicz.

For her fifth championship defense, Jędrzejczyk squared off against surging Brazilian powerhouse Jessica Andrade. The 115-pound pair locked horns in the co-main event of UFC 211.

Andrade was riding a three-fight win streak going into her championship bout with Jędrzejczyk. The Brazilian had a reputation for being a lethal finisher, with five TKOs and seven submission victories under her belt at the time.

In one of the most skilful performances of Jędrzejczyk's professional career, the reigning strawweight queen completely neutralized all of Andrade's weapons and made light work of the challenger on the feet.

Jędrzejczyk's world-class striking was a sight to behold in this championship fight as she picked apart the hard-hitting Andrade with relative ease. Moreover, she stuffed every single takedown attempt en route to a masterful unanimous decision victory.

The final scorecards read 50-45, 50-44 and 50-45, with Joanna Jędrzejczyk winning all five rounds, according to all three judges. Her resounding win over Jessica Andrade prompted many to label the Polish talent as one of the best pound-for-pound fighters in all of women's MMA.
