Joe Ariola was drafted in the seventh round of the 2025 MLB Draft out of Wake Forest, and though he didn’t make his professional debut until 2026, he rocketed up the Diamondbacks’ system.
Ariola was originally assigned to Low-A Visalia, pitching two scoreless innings in his first game with three strikeouts, but an elbow injury took him out until early July.
“I had a couple loose bodies – some bone spurs broke off in the back of my elbow,” he said. “It wasn’t really all that fun. But kind of unfortunate.
Really, no speedy recovery for that. You’ve kind of just got to sit and wait till they reattach or you take them out. So we chose to sit and wait. Ultimately, it took a little bit out of the season, but I was able to make up for it in the back half. [I] got a lot of innings plus the Fall League now, so coming up on a full year. So I didn’t get to miss out on much, just missed the first half.”
Ariola returned to action on July 4 in a rehab assignment with the ACL Diamondbacks. In three appearances (two starts), Ariola pitched 3.1 total innings and allowed two hits and one earned run with seven strikeouts and one walk. He then made his way back to Visalia, where he stayed for just five games before being promoted to High-A Hillsboro. In 10 appearances for the Hops, Ariola allowed eight runs (five earned) across 16.1 innings. He allowed seven walks, but struck out 30.
That was enough to earn him a late-season cameo with the Double-A Amarillo Sod Poodles, where he made his final two appearances. That proved to be the highlight of his year (and enough for him to win AZ SnakePit’s Minor League Reliever of the Year).
“It’s got to be winning the Texas League Championship,” he said. “I mean, joining those boys at the end of the year and doing that run with them – just seeing their camaraderie and being able to join them, it was awesome. We had a great run. I mean, I don’t think any of our expectations on the team were what it was like for their season, and then rolling into the playoffs. I think we were just happy playing still and continuing ball, but it was an awesome ride (for) those two weeks for the playoffs.”
In his two appearances, Ariola allowed just two hits across three innings with four strikeouts. In total, Ariola pitched 34.2 innings across 21 appearances and posted a 1.56 ERA and 1.04 WHIP.
2026 offered him a lot of lessons, too. The biggest one was, “Keep it simple.”
“I feel like oftentimes we’ll make things more complicated and think a little bit too much out there on the mound or hitting or whatever it may be,” he continued. “I feel like we’ve played this game for 20-plus years —or since we were born, basically, most of us now at this point. I mean, we know how to play. Keep it simple. Let your talent do it. Understand what you do well, and just do what you do well. (You’ve) been doing it your whole life.”
Heading into the Arizona Fall League, Ariola had one main goal in mind: Limit the running game.
“I talked with our coach, [Javier] Colina, in Double-A, and that was basically an area of improvement for myself,” he said, “being able to manage guys when they do get on, don’t give up free 90’s (feet) and stuff, don’t let them get into scoring position super easily. I’ve been trying to work on it (and) mix it in when I can.”
But Ariola, like the other prospects, is also taking advantage of the different perspectives afforded to him in the Salt River Rafters bullpen.
“It’s awesome, honestly,” he said. “We talk it up all the time in the bullpen with the guys, and you get to pick some brains on what different orgs are like – how some of the big orgs do it, how some of the small orgs do it. Some guys have been traded into stuff, how that looks, and it’s a lot of perspectives and a lot of different journeys all mixed together in the bullpen.
Even on the team in general, like coming down here with the hitters,” he continued, “so I feel like that’s some of the biggest stuff you can get from one another. And then, along with the coaches, everybody’s got a different philosophy from the different orgs. So (you) pick a little bit from each guy, and you see what works for you.”
One of the best things, though, has been reuniting with his former college teammate — Rockies LHP Sean Sullivan.
“It was awesome, honestly. I was looking forward to it when I saw that our teams were kind of mashed up,” Ariola said. “I didn’t know he was going to be on it, but I was like, ‘Alright, cool. I’m going to be in the Fall League playing.’ And then I saw his name on the list, and I was like, ‘Damn, I haven’t seen him in three years. This is going to be awesome.’ We had a good run in college together. I was good friends with him in college, and I love him. So it was awesome to come back here and be able to be on the same team again.”
Ariola is known for his curveball, which breaks in a traditional 12-6 fashion and hovers around 78-81 mph. But what makes it so good?
“Maybe because I throw a really high slot, and maybe it looks like another pitch,” he said. “I can’t really tell you. When I learned how to throw it, it was when I was a kid. I haven’t changed it since. I mean, it’s always been my pitch that I was really good at. I don’t try to tinker with it all that much. I just try to believe in it every time I throw it.”
But it plays really well against his fastball, which hovers around 93-95 mph. And that fastball is the pitch that Ariola identified as his favorite in his arsenal.
“[I’m] really consistent with that one,” he said with a slight smirk. “I feel like I could throw that at any point right now.
“But the curveball is definitely the go-to out pitch,” he continued. “If I’ve got to get a guy to swing and miss, it’s going there. But I like the heater.”
Heading into the offseason, Ariola is looking forward to “understanding exactly what I need to work on, and then taking it into the offseason, figuring those things out and then coming back in the spring and seeing how much I’ve adjusted, gotten better, and improved. I think that’s some of the stuff I’m really looking forward to this offseason. Just tinkering a little bit on small things. What can I get better at?”
And what does he want fans know about him? Like teammate Demetrio Crisantes, Ariola is “pretty easygoing and laid back.
“If you want to come up and talk, I’m down to talk,” he said. “I’m a friendly person. I don’t mind if you come and introduce yourself to me. Go for it — I’m down to meet new people.”
