LAS VEGAS – Dana White’s Contender Series returned Tuesday with five fights on ESPN+ from the UFC Apex in Las Vegas – and all five walked away with UFC contracts.

In the featured fight of the night, middleweight Dustin Stoltzfus (13-1) picked up a victory over Joe Pyfer (7-2) in odd fashion.

Pyfer was the one walking forward in the early going, but Stoltzfus landed several hard low kicks as he retreated. Pyfer appeared the bigger man and was powerful with his hands when he let them go, but Stoltzfus was certainly doing some damage to the legs.

The fight transitioned to the floor late in the frame, and Pyfer took top position, posturing and looking to strike. From his back, Stoltzfus threatened with a triangle choke, then turned for a heel hook. Pyfer alertly spun free from the hold, but as the two moved to the feet, Stoltzfus wrapped the body and elevated his opponent before slamming him to the floor. As Pyfer went to the floor, he posted with his right arm, which visibly dislocated in gruesome fashion, ending the fight at the 4:21 mark of the first frame.

In bantamweight action Adrian Yanez (11-3) used slick, accurate striking to score a rapid-fire finish of Brady Huang (11-2).

After a brief exchange of strikes, Huang shot inside for a takedown but was pushed away with relative ease. From there, Yanez landed a crisp left hand that saw Huang drop to a knee. He popped back up, but Yanez delivered a few more pinpoint shots to the chin. Huang went again to a knee, and though he tried to get his feet under him, referee Jason Herzog called off the fight as the clearly wobbled bantamweight fell back to the cage. The end came in just 38 seconds.

In a strawweight matchup, Cory Mckenna (5-1) outlasted her opponent’s frequent submission attempts to earn a unanimous decision win over Vanessa Demopoulos (5-2).

Demopoulos attacked the legs early, verbally punctuating every strike, but McKenna was cool under fire and returned punches up top. Demopoulos fell to the canvas in the opening minute, but when McKenna followed to the floor, she found herself instantly threatened by her opponent’s left leg across her shoulder. It took McKenna some time, but she did finally clear the threat, and she set up in her opponent’s guard.

Demopoulos continued to try and bring the legs high as she worked from her back in rubber guard. She didn’t ultimately succeed, but it did prevent McKenna from ever truly capitalizing on having top position, where she finished the round.

The two exchanged strikes on the feet to start the second, and both women found moments of success. McKenna found her rhythm and countered perfectly over a few low kicks, visibly snapping her opponent’s head back. Demopoulos went willingly to her back early in the frame, and she immediately started to work rubber guard once again.

Demopoulos meticulously worked her way into a triangle choke, but McKenna pressed from the top and forced an adjustment. Demopoulos tried to switch to armbar, but she ultimately had to let it go and look to scramble to a better position. Instead, it was McKenna who worked to her opponent’s back and finished the round with punches.

McKenna found a home for her jab early in the third and snuck in a slick high kick, as well. Demopoulos did her best to try and move in and out of range on the feet, even attempting a cartwheel early, but McKenna got the best of the exchanges. Demopoulos then went willingly to her back once again, but McKenna was able to tag her with several punches from the dominant spot.

Demopoulos eventually got her hips in position for an armbar, but McKenna did her best to keep her opponent stacked and her arm secure. Demopoulos made a last-ditch effort at extending the limb, but McKenna gutted through it and pulled free. The two then returned to the feet, where they traded punches until the final bell.

In the end, judges awarded McKenna the win, 30-27, 29-28, and 29-28.

In a featherweight matchup, TJ Laramie (12-3) survived some early submission trouble to battle back and stop Daniel Swain (20-10-1) in the opening round.

Laramie took the center to start the contest, and he used a big right hand to forward and into the clinch, where Swain was forced to defend a takedown attempt against the fence. With nothin there, Laramie backed away and then was able to get the action to the canvas during a wild scrambling exchange.

Working from his back, Swain quickly secured his opponent’s wrist and began hunting for the armbar. He switched his hips several times, looking for the proper angle, but he was never able to get enough pressure on the elbow. Once Laramie worked his arm free, he looked to work ground-and-pound attacks from the top. Swain was always active, looking for opportunities from his back, but Laramie was able to stay on top and continue striking until the end of the frame.

Swain was slow to rise at the end of the round, and he clutched his ribs as his corner addressed him. Before the start of the second, the doctor came in to check his status, and the contest was ultimately called off.

In the night’s first contest, middleweight Impa Kasanganay (7-0) kept his undefeated record intact with a clearcut decision win over Anthony Adams (8-2).

The initial exchange of the contest saw Adams land inadvertently to the groin, leading to a brief timeout. On the restart, both men threw heavy punches and kicks for the opening minute before settling into a more sustainable pace. Adams did his best to use range to his advantage, while Kasanganay chopped at the legs while also looking to set up his hands up top.

Adams frequently used a front kick from range and looked to utilize knees when the two worked in tight. Meanwhile, Kasanganay was able to score with several powerful hooks along the way.

In the second, Kasanganay turned up the pressure a bit, working the legs and firing punching combinations up top. Adams was unfazed and fired back with his long, straight punches. But it was Kasanganay who was generally quicker on the trigger and flashed a few creative attacks with odd-angled elbows and a spinning attack.

Kasanganay eventually turned to a takedown with 90 seconds left in the frame, and he maintained the dominant position until the end.

With the fight likely hanging in the balance to start the third, both men came out swinging. Kasanganay moved quickly to the clinch and was able to slip around to his opponent’s back. With Adams in a kneeling position, Kasanganay began firing big punches that landed clean to the face. Knees to the body followed, and referee Mark Smith warned Adams to move.

Adams finally turned inside with 90 seconds left, but Kasanganay stood and turned to the outside. He was clearly in control of the contest but landed an unfortunate knee to the groin that earned Adams a lengthy rest.

Despite taking nearly the full five-minute period, Adams wasn’t able to show much on the restart. With less than a minute to work, it was Kasanganay who came out firing big shots and then once again moved to the back in a grappling exchange before the final bell. In the end, it sealed the decision win for Kasanganay, with 29-27 scores on all three judges’ cards.
