If the Diamondbacks are looking ahead to 2027, the blueprints are starting to show up in the minors and on the mound. Two names in particular stand out from the latest round of chatter around the organization: Gerardo Carrillo and Manuel Pena.
Carrillo’s path has been a long one. Signed as a Minor League free agent in the offseason, the right-hander finally reached the majors in late July at age 27 after eight seasons in the Minors.
His debut was a modest one - he gave up a run over two innings - but what followed was more intriguing. Over his next nine outings, Carrillo threw 14 1/3 innings without allowing an earned run and piled up 18 strikeouts.
The catch, as always with Carrillo, is the control. He walked 16 batters, including one intentional free pass, in 17 1/3 innings overall.
Still, the stuff is loud enough to keep him on the radar, especially with several relievers due to leave in free agency. As Slivka put it: “He has electric stuff,” Slivka said.
“Upper 90s fastball, low-to-mid 90s cutter, a nasty split. We saw some inconsistencies with control.
When he got sent down, we worked through some things in his delivery to help him find the zone more frequently, and he really started to dial things in.”
Pena brings a different kind of intrigue. The power-hitting infield prospect turned heads in 2026 by blasting 31 home runs across Double-A and Triple-A.
He also put together a .305/.345/.555 line for a .900 OPS between the two stops, though his production wasn’t identical at both levels. In Amarillo, the numbers were huge.
In Reno, things settled down a bit, and he finished with a .746 OPS.
The swing-and-miss is part of the package too - Pena struck out 119 times in 2026 - and he’d benefit from a more all-field approach. But the raw pop is obvious, and Arizona is still searching for more thump at first base. He probably won’t break camp with the big club, but if he starts fast and shows progress, he’s a name that could surface in the majors during the season.
Elsewhere in baseball, the postseason is already delivering some noise. Cleveland opened the ALCS by stunning Tampa Bay with a 7-3 comeback win on Monday night. The Rays controlled the first six innings, looking like the same precise, suffocating team that got them here, before the Guardians flipped the script with the power and timely hitting that carried them through the year.
In the NLCS, Milwaukee and Los Angeles have wasted no time living up to the hype of a matchup between two 100-plus win teams. After two games, the Brewers have turned the series into an uphill climb for the defending champions.
The challenge system is also getting plenty of run in the playoffs. Across the Wild Card Series and Division Series, 71 of 121 ABS challenges were successful.
That 59% success rate is up from 54% during the regular season. Batters have had even better results, winning 29 of 51 challenges for a 57% success rate, compared with 49% in the regular season.
Teams are challenging more often overall in October too, averaging 4.8 per game, up from 4.3, with batter challenges rising to 2.04 per game from 1.96.
And one more bit of postseason roster intrigue: the Dodgers are reportedly considering benching Ohtani in Game 3. If that happens, 21-year-old Josue De Paula would likely get his first career playoff start.
Los Angeles has used the top prospect as a bench bat since calling him up in September, and he’s already made a mark with two walks in three postseason plate appearances. He drew a key walk against Didier Fuentes to help the Dodgers seize a decisive lead in Game 4 of their Division Series, then kept Game 1 of the NLCS alive with a two-out walk against Trevor Megill in the ninth.
The rally fell short when Mookie Betts flew out to end a 2-1 loss.

Diamondbacks Offseason Focus Is Getting Hard To Ignore
The Diamondbacks are only starting to sort through their offseason business, but the direction is already becoming clear. Mike Hazen said trade talks are still in the early stages, and the front office has one problem it knows it needs to address: getting better against right-handed pitching. First base and designated hitter stand out as the most obvious places to look, which gives Arizona a fairly clean roadmap even before the winter market really gets moving.
There is also some movement on the staff side, where Brian Kaplan was not retained after his contract expired even as Hazen expects the rest of the coaching group to be back. On the mound, Corbin Burnes offered a bit of reassurance after a shoulder inflammation issue came up following a teres major strain that had already pushed back his return from Tommy John surgery. He said there are no structural concerns and that he plans to get back to normal offseason throwing once he heals, which is about as important a note as Arizona could ask for right now. [Read more 🡒]
