Jack Mahoney (No. 15 PuRP) finished the 2025 season in the Arizona Fall League and was assigned to repeat Double-A Hartford to start the 2026 season. But that seemed to work well for the right-hander, as he posted a 1.99 ERA in 13 starts before being promoted in early August.
And the promotion came on the heels of winning Rockies Organizational Pitcher of the Month for July.
“I think it’s just kind of a tribute to putting one foot in front of the other and trying to continue to just become the best pitcher I can be and pouring into that,” Mahoney said of the win. “It’s obviously a great nod, but (I’m) just kind of focused on trying to continue to develop and become the starter that I want to be.”
And part of that first half included the Yard Goats winning the first half in the Eastern League, which was a highlight for Mahoney.
“Everyone talks about how great of a league that is, so having that group together down there in Hartford and getting to play with them and contribute to winning the first half down there, that was definitely the highlight,” he said.
Mahoney made five starts and posted a 1.65 ERA leading up to his win and promotion, and he has continued to take a step forward in Albuquerque. In his Triple-A debut, Mahoney pitched five innings and allowed two runs on six hits with one home run, two walks, and six strikeouts. And he’s been making adjustments throughout the season.
“I think seeing the hitters be more disciplined in approach and swing decisions and trying to put together reports pregame and throughout the week, and watching some guys on where they want to hit the baseball,” he said.
One of the big things Mahoney has had to adjust to is the use of the ABS system, which doesn’t exist in the lower minors. So the coaches make sure to provide more advanced scouting reports to the pitchers and catchers.
“These guys don’t really want to come out of the zone – nor should they,” he said. “I think that’s just kind of been one of the bigger (things) is throwing into that strike zone now, where guys are probably more disciplined in their approach. So just trying to marry that with what works for me and how I’m going to get those guys out.”
And that has forced Mahoney to see the strike zone in a different way, and refine the way he pitches.
“I think for me, just a big thing since I’ve been up here, too, is just talking about trying to eliminate as many ‘uncompetitive pitches’ as possible, just because that’s a wasted bullet in our eyes,” he explained. “I just think with the strike zone now, it just kind of shrinks down – the competitive looks that you’re going to give guys.
“So I think just through bullpens and just through innings up here so far, I’m learning, ‘Hey, this pitch is going to play here and let’s try and stay out of the zone with this one,’” he continued. “But yeah, just trying to put that approach together and furthering my knowledge of lineups throughout the week doing advanced reports and talking to a lot of people about what it should look like.”

One of the more unique things about Triple-A is that there are always players coming and going, including veteran players on rehab assignments. But that hasn’t phased Mahoney who say’s he’s still “trying to learn as much as I possibly can and apply that to what I think I do well, or maybe not do so well, right now.
“I think it’s really important for me – whether it’s a hitter or a pitcher who have been on that stage,” he continued. “I want to pitch up in the big leagues, so I think it’s just really important that you stay in your lane about it, but also just try to build that relationship and develop that with these guys that have been there, done that, almost and gotten time up there and seen what it’s about. I think every level you go up, the level of play increases, and so just trying to learn as much as possible and trying to be as prepared as possible from that day, when that day comes.”
And another thing about the minors, and baseball in general, is the potential for movement. For Mahoney, this was the second time he was promoted mid-season, and he was grateful he’d done it before so he knew better what to expect.
“Obviously, you want to get promoted, but I think the first time, maybe you get sped up a little bit and you’re just in a new spot with a new team, new guys, new dugouts, new everything,” he said.
“So I think this time, it was just about being as consistent as I could be in my routine that I’ve stayed in every day since the beginning of the year, and just having that routine when I show up to the field. It really kind of is that familiar feeling for me.
“Going from Double-A all the way out on the east coast and flying across the country – I think I showed up to the Hartford Airport and then I met the team out in El Paso — it was a long trek,” he continued, “but just trying to slow everything down and realize that it’s still a locker room. It’s baseball. This is what I love to do, and just slow the heart rate down and slow the days down, and just try to get settled and pack up your good clothes and throw the rest of your clothes in your car and get out to the other affiliate.”
Mahoney has also been adjusting to the elevation of the Pacific Coast League. RGCU Field at Isotopes Park sits at 5,100 feet, which is just a tick under Coors Field.
“I think it’s one of those things where you don’t really understand it until you’re in it,” he said, and definitely in my first couple of starts, I’ve seen what that’s all about. So I think it’s just kind of taking that information and not just looking at it as like, ‘Oh man, this doesn’t move as much’ or looking at it as a bad thing – just learning how to adjust to it.
“So I think the biggest thing that we talk about right now is just kind of adjusting our sights because, obviously, the pitch is going to have less movement,” he continued. “So you’ve got to figure out where to start things and how it’s still going to play as well as you want it to when you’re pitching at sea level. So just understanding that and understanding that’s where you’re at that day, and just really adjusting the sights and trying to get reps under your belt – especially as a starting pitcher, just because you’re going to be out there for 100 pitches or whatever. Just understanding when you’re going to let those shots go, and just where you want to start.”
But overall, it was a “solid year” for Mahoney, who has posted a 5.47 ERA in six starts for the Isotopes. He has allowed two runs in four of his starts, and four in the other two.
“As far as development goes, [I’m] just trying to figure out what makes me the best pitcher I can be,” he said. “I have three starts left here, so I’m just really looking forward to continuing to get innings under my belt at this level. I’ve got two more starts in Albuquerque, so I think getting two more starts under my belt with the elevation and understanding what that looks like for me.
“It’s been a pretty fun journey this year,” he said. “I think [it’s] just continuing to pour my energy into developing and becoming the best starter I can be.”
Weekly Pebble Report: September 1st-6th
Triple-A: Albuquerque Isotopes (2-4, 67-71 overall)
The Isotopes lost the series 2-4 against the Tacoma Rainiers (Mariners), but it was a high-scoring affair. The Topes were outscored 38-35 across the six games. It marked Albuquerques 11th series loss of the year, including their sixth at home and third in the last four sets. Even though they won on Sunday, they still have lost 14 of their last 20 games and six of their last eight.
⬆️ Stock Up: The Condor is soaring!
Charlie Condon (No. 2 PuRP) had an outstanding week that capped off with hitting two grand slams on Sunday against the Rainiers. He became the second Isotope to achieve such a feat, and the first to do it at RGCU Field at Isotopes Park — Jerry Sands hit two on July 29, 2012 at the Nashville Sounds (Brewers) when the Isotopes were still an affiliate of the Dodgers.
Overall, Condon went 8-for-24 with two doubles, three home runs (including the two grand slams), 11 RBI, five runs scored, two walks, nine strikeouts and a stolen base.
Upcoming: The Topes head out on the road for the final time, traveling to Reno to take on the Aces (Diamondbacks), before returning to Albuquerque for their final homestand next week.
Double-A: Hartford Yard Goats (3-3, 64-67 overall)
The Yard Goats split their final series of the year 3-3 against the Reading Fightin Phils (Phillies). They outscored the Phils 28-27, and two high-scoring games: a 10-5 loss on Thursday and a 9-o shutout victory on Saturday. After winning the first half on June 19th — the earliest in club history — the Goats will host Game 2 and Game 3 (if necessary) in a Best of 3 ELDS starting next Tuesday.
⬆️ Stock Up: Stu on it
Stu Flesland III continues to impress in Hartford, making one start this week against Reading. Flesland tossed 5.2 scoreless innings with two walks and seven strikeouts. Flesland originally joined the Yard Goats as a reliever, making six appearances out of the bullpen before joining the starting rotation in July. He has made 11 starts and has only given up three or more earned runs three times.
Flesland has gotten better as the year has progressed, and was named Eastern League Player of the Month and Rockies Minor League Pitcher of the Month for August after posting a 1.29 ERA across six starts (35.0 innings).
⬆️ Stock Up: Jacob Humphreykeeps hitting
Jacob Humphrey had an outstanding week, going 7-for-21 with three runs scored, two walks and five strikeouts this week against Reading. He also stole two bases. Humphrey was promoted on August 18 after a stint on the 7-day injured list, but didn’t let the injury slow him down. Since his promotion, Humphrey has gone 21-for-43 (.328) with three doubles, three RBI, four walks, 12 strikeouts and seven runs scored. He has also stolen six total bases in six attempts in Hartford.
Upcoming: The Yard Goats will head to Somerset to take on the Double-A affiliate of their Major League opponent — the Somerset Patriots (Yankees) — for their final series before playoffs begin next Tuesday.
High-A: Spokane Indians (2-4, 58-73 overall)
The Indians limped to the finish line, going 2-4 in their final six games and being outscored 42-26. However, they ended on a high note with a 10-4 victory over the Everett AquaSox (Mariners).
Fun Fact: Entering Sunday’s season finale, the Indians have recorded 11 walk-off wins in 64 home games this year (that’s roughly one walk-off win per homestand). Spokane’s 11 walk-offs are five more than the next closest Northwest League team (Vancouver, 6) and more than any MLB team (Chicago White Sox, 10).
⬆️ Stock Up: Robert the Magnificent
Robert Calaz (No. 26 PuRP) had a strong showing in the final week. The outfielder went 7-for-18 with four doubles, two home runs, four RBI, three runs scored, two walks and six strikeouts across five games in September. He also finished the year with a 20-game on-base streak, including hits in 16 of his final 17 games. Overall, Calaz slashed .237/.312/.396 in 105 games with Spokane this season.
⬆️ Stock Up: He’s a Wild(er) man!
Wilder Dalis (No. 10 PuRP) finished 2026 strong, going 9-for-25 with a double, two home runs, four RBI, five runs scored and five strikeouts. He didn’t walk nor steal a base in the last week. In total, Dalis slashed .322/.344/.492 with one double, three home runs, seven RBI, nine runs scored, two walks and 12 strikeouts across 16 games in High-A.
Upcoming: The Indians finished fifth in the second half (out of six) and sixth overall on the season, so their season is over for 2026.
Low-A: Fresno Grizzlies (1-5, 69-63 overall)
Fresno had the hardest go in the final week of the season, mustering just one win against the San Jose Giants — a 6-2 victory on Wednesday. Overall, they were outscored 35-28. Entering the final game, they needed a win and a Stockton loss to Visalia to force a tie in the second-half standings and get the Grizzlies into the postseason. Unfortunately, that did not happen and the Grizzlies’ season ended on Sunday.
Fun Fact: In 2026, Fresno has gone 26-15 in one-run decisions (.634 winning percentage). That helped them in their final playoff push, but it ultimately wasn’t enough.
⬆️ Stock Up: Andujar bounces back
Ashly Andujar (No. 30 PuRP) finished the year strong, going 8-for-26 in his final six games against the San Jose Giants. He also recorded two doubles, two RBI, five runs scored, two walks and eight strikeouts with one stolen base. He recored two hits in four of his final six games, while in the others he went 0-for-5 and 0-for-4, respectively. Andujar started the year by repeating the ACL, but then had a decent season after he was promoted on May 24, slashing .242/.301/.324 with 10 doubles, four triples, three home runs, 33 RBI, 47 runs scored, 26 walks and 72 strikeouts. He also stole six bases in 10 attempts.
⬆️ Stock Up: Shine like a (Van) Sickle
Bryson Van Sickle had an outstanding final showing of the season, tossing seven innings against San Jose and allowing just two runs (one earned) on two hits with nine strikeouts. It’s been an up-and-down year for the left-hander, but he ended on a high note.
Upcoming: Like the Indians, the Grizzlies finished third in their division in the second half after their loss to San Jose, so despite finishing second overall in the California League North, they missed the playoffs and their season is over.
