On Saturday the UFC heads back to the rarified air of Mexico City, which sits 7,200 feet above sea level. Perhaps as a nod to that high altitude, the promotion has stacked the card with lighter-weight competitors, with the majority of the bouts taking place at bantamweight or lighter.

One of those sub-135-pound battles gets top billing. Young rising flyweight stars Brandon Moreno and Sergio Pettis headline this event. It’s a big fight for Moreno, who goes by one of the more colorful nicknames in the UFC, “The Assassin Baby.” Just three fights into his UFC career, the promotion tasks the Mexican-born competitor with headlining an event in his home country against an opponent with much more UFC experience.

In the co-main event, another young Mexican-born fighter, Alexa Grasso, looks to bounce back from her first career defeat when she meets the more tenured Randa Markos.

UFC Fight Night 114 takes place at Mexico City Arena, and it airs on FS1 following early prelims on UFC Fight Pass.

Here are 10 reasons to watch the event.

1. Closing in

In a flyweight division in need of fresh challengers, the winner of the matchup between Moreno (14-3 MMA, 3-0 UFC), currently No. 9 in the USA TODAY Sports/MMAjunkie MMA flyweight rankings, and No. 8 ranked Pettis (15-2 MMA, 6-2 UFC) could find himself one or two fights away from a title shot.

Moreno has come on like gangbusters since joining the UFC in October, going 3-0 while pocketing $100,000 with two fight-night bonus awards. The 23-year-old is exciting and charismatic, with an aggressive fighting style that will surely make him the fan favorite in his native Mexico.

Pettis, also 23, has much more octagon experience. A UFC competitor since 2013, he’s won his past three fights, all by decision. Pettis is a much more controlled and patient fighter than Moreno, and that could play a part in this contest. Neither of these two has gone five rounds, and doing so at altitude could prove taxing.

2. Looking for a star

The UFC bit hard upon signing Grasso, selling her as a future star. While she won her debut, defeating Heather Jo Clark, she dropped her second fight, to Felice Herrig. At UFC Fight Night 114, the 23-year-old Mexican fighter gets another tough test in Markos.

The 31-year-old Markos delivered one of the best performances of her career in her last outing while earning a split-decision win over former strawweight champion Carla Esparza. Markos changed up her training regime before that fight, and it paid dividends.

If Markos (7-4 MMA, 3-3 UFC) can take out Grasso (9-1 MMA, 1-1 UFC) and put together her first two-fight winning streak since 2013, she’ll be in line to face a ranked opponent.

The loss to Herrig was the first of Grasso’s career. Look to see how she bounces back from that defeat, what overall progress she has made, and how she handles the pressure of facing a fighter with more high-level experience than she has.

3. Unbeaten, but untested

Niko Price has had two short-notice UFC fights. He’s won both by stoppage, but his most recent victory was later ruled a no-contest due to a failed drug test for marijuana. At UFC Fight Night 114, fans get to see how Price fares with more than two weeks to prepare for an opponent. Price faces nine-fight UFC vet Alan Jouban at welterweight.

Unbeaten Price (10-0 MMA, 2-0 UFC) has never fought someone as well-rounded as Jouban (15-5 MMA, 6-3 UFC), who’s coming off a submission loss to Gunnar Nelson in his last bout. But before that, he was on a three-fight winning streak that included a decision win over Mike Perry. That Perry fight showed Jouban could stay with a smart game plan against an aggressive and maybe a little reckless opponent – adjectives that could also describe Price.

4. That’s a lot of stoppages

Martin Bravo hasn’t fought since he won Season 3 of “The Ultimate Fighter: Latin America” in November by knocking out Claudio Puelles. He meets UFC newcomer Humberto Bandenay at featherweight.

The 23-year-old Bravo is unbeaten as a pro, but he remains a developing prospect. He’s comfortable and aggressive wherever the fight may go, and he’s won five fights by submission and four via TKO.

Bravo faces 22-year-old Bandenay (13-4 MMA, 0-0 UFC), who despite being younger than Bravo (11-0 MMA, 1-0 UFC), has six more fights to his name. Bandenay is on a five-fight winning streak, and he’s won each of those bouts by stoppage, including his most recent outing: a May submission of Salim Mukhidinov at KOTC.

5. Give it a second shot

Former UFC light heavyweight champion Rashad Evans enters his fight against Sam Alvey on a three-fight losing skid, the longest of his career. Evans made his middleweight debut in his last outing and dropped a split decision to Daniel Kelly. That loss came after a layoff of nearly a year. Now that he’s blown off the ring rust and has a feel for middleweight, don’t be surprised to see a much more active Evans (19-6-1 MMA, 14-6-1 UFC) against Alvey (30-9 MMA, 7-4 UFC).

Alvey saw his four-fight winning streak come to an end in his last fight, an April unanimous-decision defeat to Thales Leites.

6. Looking to shine

With a Cage Warriors belt on his resume and an eight-fight winning streak to his name, Jack Hermansson defeated Scott Askham in his UFC debut. Hermansson followed that victory with a submission loss to Cezar Ferreira. In his third UFC bout, Hermansson earned a first-round knockout win over Alex Nicholson.

Hermansson (15-3 MMA, 2-1 UFC) gets a chance to capitalize on that May KO win when he meets Brad Scott (11-4 MMA, 3-3 UFC), who’s alternated wins and losses throughout his six-fight UFC run. He most recently defeated Askham via split decision in March.

Both of these middleweights like to stay busy on the feet, so this could prove to be a fun scrap between two fighters looking to increase their name recognition in an increasingly crowded roster.

7. Stay off the ground

Three fights into his UFC career, and Team Alpha Male fighter Hector Sandoval looks like he could make a charge up the flyweight ranks. He’ll get a chance to do just that against No. 13-ranked Dustin Ortiz.

Sandoval has displayed quickness and good striking in the clinch, and he can take his opponent to the mat if he runs into issues on the feet. He packed all of those talents into his last fight, a first-round TKO win over Matt Schnell.

Ortiz (16-7 MMA, 5-5 UFC) is best known for his wrestling base, but he could have problems when it comes to Sandoval (14-3 MMA, 1-2 UFC), who has a 71 percent takedown defense. If Ortiz does get this fight to the ground, expect him to keep it there since he has some of the best top control in the division.

Ortiz has gone 2-4 in his past six fights, including his first career submission loss in his last outing when Moreno stopped him.

8. That has to sting a bit

In July 2015, unranked bantamweights Henry Briones and Cody Garbrandt met at UFC 189. Garbrandt won that contest by unanimous decision. Four fights and 17 months later, Garbrandt claimed the bantamweight title, defeating Dominick Cruz. Briones was inactive during most of Garbrandt’s run, competing once when he lost to Douglas Silva de Andrade by third-round TKO in November.

Briones (16-6-1 MMA, 1-2 UFC) faces longtime WEC/UFC competitor Rani Yahya (23-9 MMA, 8-3 UFC) in his return bout. Briones is best known as a brawler while Yahya, who enters this fight coming off a decision defeat to Joe Soto, has been trying to shed his reputation as a ground-control fighter by opening up his striking, something he did in his loss to Soto.

This could be a sleeper pick for slugfest of the night.

9. Fresh and unbeaten

Two unbeaten flyweights, Joseph Morales (8-0 MMA, 0-0 UFC) and Roberto Sanchez (7-0 MMA, 0-0 UFC), close out the UFC Fight Pass prelims.

If you recall, Morales is the fighter Cynthia Calvillo implored UFC President Dana White to sign after her UFC 209 win. White did that after Morales knocked out former Cage Fury and Ring of Combat flyweight champion Sean Santella in March at Cage Fury 64. The victory gave the 22-year-old Team Alpha Male product six stoppages in eight fights.

Sanchez enters the UFC after winning the LFA flyweight title at LFA 14. The 31-year-old Sanchez took out Jerome Rivera that night, submitting him in the third round. The victory was Sanchez’s fifth consecutive submission victory.

10. Trying to stick

After spending time with RFA, WSOF, Legacy FC and a stint in “The Ultimate Fighter” house, Jordan Rinaldi got his opportunity to step up to the big show in May 2016, when he took on Abel Trujillo in a short-notice bout. Rinaldi represented himself well through the first two rounds, but he faded in the third, and that allowed Trujillo to touch him up in the striking department and earn the decision victory, bringing an end to Rinaldi’s five-fight winning streak.

At UFC Fight Night 114, Rinaldi matches up against a fighter who is more in line with his experience level, Alvaro Herrera, who is coming in off a submission loss to Vicente Luque in July 2016.

This lightweight fight might give Rinaldi (12-5 MMA, 0-1 UFC) the opportunity to show off his ground chops as Herrera (9-4 MMA, 1-1 UFC), a striker, is not known for his takedown defense.
