Kyler Fedko's contract has been selected by the Twins. His first appearance in a game will mark his MLB debut!

[Uncharted Fields @UnchartedFields]

Kyler Fedko (26/MIN) has looked even better at AAA this year, putting up a .288/.382/.596 slash in 170 PAs. There are some chase issues still, but he's coming off a 28 HR / 38 SB season and is already showing more power than a year ago.

[Uncharted Fields @UnchartedFields]

Caden Hunter (22/A+/BAL) was a '25 6th rounder that looked sharp in his high-A debut (4.1 IP / 2 H / 0 ER / 9 K / 2 BB) on Saturday. Among 555 MiLB pitchers with 20+ IPs and 6+ starts, his 2.24 xFIP ranks 1st. He has yet to reach 5 IPs in a start yet.

[Uncharted Fields @UnchartedFields]

Will be interesting to see if Austin Dean (32/KBO/LG) ever attempts an MLB comeback. He's currently 3rd in wRC+ among qualified KBO hitters with a 168. His .336/.413/.607 slash comes with a sparkling 12.5% K-and 10.8% BB-rate. Dean has been an offensive force for over 3 years now in Korea.

[Uncharted Fields @UnchartedFields]

Jeremy Beasley (30/KBO/Lotte) jumped over from the NPB to the KBO this past offseason and has managed to up his K-rate while simultaneously pitching longer into games. In 11 GS (58 IPs), he has a 4.50 ERA / 3.14 FIP / 3.43 xFIP with a 26.5 K% and 6.5 BB%.

[Uncharted Fields @UnchartedFields]

Sean Hjelle (29/NPB/ORX) has converted to a SP in his first season overseas and the early results are hard to argue against. In 45.2 IPs (8 GS), he has a 1.58 ERA / 2.27 FIP / 2.99 xFIP. The K-rate is lower at 19.1%, but he could make the case for an MLB return next offseason.

[Uncharted Fields @UnchartedFields]

@JonPgh VS2 has been such a letdown. Feel like he needs a long reset in AAA to try and right the ship.

[Uncharted Fields @UnchartedFields]

Jared Young (30) returned from injury a few days ago and currently has a .348/.407/.435 slash in 23 ABs on the year. He's had quite the journey in his career and while I don't expect him to hit over .300, his numbers and batted ball data at AAA still scream late-career breakout potential to me. It's likely a strong-side platoon profile at best, but it would be great to see a team finally give him some run. I don't know if that will happen with the Mets, but they also likely didn't plan on being in last place in the NLE heading into June.

[Uncharted Fields @UnchartedFields]

Jared Young (1B, CHC) turns 28 in a few days and isn't the big-name 1B prospect that comes to mind for the Cubs, but he's put up a .326/.426/.605 line in AAA this year. In the last two weeks he's batting .390 with 6 HRs. 1B situation is odd in CHC, which could help at some point

[Uncharted Fields @UnchartedFields]

Nick Sogard (28) and Mickey Gasper (30) have both shown surprisingly good batted ball data in the minors recently and I think could prove to be useful additions to the Boston lineup. After today's game, they are hitting .300 and .326 (respectively) in the early going.

[Uncharted Fields @UnchartedFields]

Kyler Fedko (26/MIN) has looked even better at AAA this year, putting up a .288/.382/.596 slash in 170 PAs. There are some chase issues still, but he's coming off a 28 HR / 38 SB season and is already showing more power than a year ago.

[Uncharted Fields @UnchartedFields]

Kyler Fedko (26/AAA/MIN) could be one of the better hitters available in this year's Rule 5 Draft, having hit 25 HRs with 38 SB (8 CS) across 566 PAs. Power dipped a bit in AAA but his batted ball data is relatively well-rounded as far as likely Rule 5 targets go. Fedko got run at all 3 OF spots and 1B as well. A RHH, he has reverse splits and could slot in as a strong-side platoon or bench option. The question will be whether he can make enough contact to stay in the lineup (if picked up).

[Uncharted Fields @UnchartedFields]

Pedro Ramirez shot up prospect lists to start the year and earned his MLB debut this past weekend (2-7 with 1 BB thus far). His batted ball backed up a strong .312/.395/.547 slash line in 196 AAA PAs, which came with 9 HRs and 19 SBs (2 CS). While the '25 numbers weren't crazy, the fact he was so young for the level should have raised more attention.

[Uncharted Fields @UnchartedFields]

Pedro Ramirez (21/AA/CHC) is amongst the youngest hitters at AA, but he's done well for himself with a 127 wRC+ on a .297/.358/.406 slash in 288 PAs. He's also got a 1.073 OPS over the past two weeks of games and might find himself in AAA sooner than expected if it continues.

[Uncharted Fields @UnchartedFields]

Alan Roden is still recovering from injury, but looked good in 87 PAs at AAA to begin the year. He hit .275/.425/.464 prior to a labrum tear in late April. He joins the other hitters as someone that still shows strong statcast numbers but possibly suffers from being too patient at the plate (which more advanced arms can better take advantage of). Still a player I very much think has upside as at least a strong-side platoon hitter though. Depending on his recovery and how much PT they would like him to get, Roden could be a possible bench replacement for Outman when healthy.

[Uncharted Fields @UnchartedFields]

Alan Roden (25, OF) received some offseason buzz last year after a strong stretch at AAA to end '24. While his debut fell flat (as did his time with MIN), the metrics still looked promising in the minors this year (to go along with the .331/.423/.496 slash). With the Twins in flux and other depth OFers looking to vulture reps, it's unclear if Roden can force his way into the picture to begin next year. While he doesn't impact the ball that hard, he does just about everything else above average and is still someone I'm tracking closely.

[Uncharted Fields @UnchartedFields]

Spencer Packard has missed most of the year with an injury sustained in early April, but is currently on a rehab assignment with their rookie ball affiliate. He's managed a 1.425 OPS in 5 games thus far and is hopefully back in AAA soon. Still difficult to see a path to any kind of playing time for now, but injuries and continued struggles from some Ms bench players could give him a chance to earn an MLB debut this year.

[Uncharted Fields @UnchartedFields]

Spencer Packard (28, OF) doesn't impact the ball as hard as others, but otherwise does everything else pretty well across the board. A 9th rounder out of Campbell (home of the Fighting Camels) back in '21, Packard hit .278/.391/.413 in 494 AAA PAs this year. That line jumps up to .293/.398/.463 vs RHPs and could be a useful platoon/bench piece if he gets a shot. That could come sooner than expected if he's picked up in the Rule 5 Draft next month.

[Uncharted Fields @UnchartedFields]

Jose Fermin has appeared at five positions in the field this year and is hitting .213/.290/.361 in 61 ABs. While the strong plate approach continues, statcast data suggests he's actually been lucky with the results. Still someone I like long-term as a capable UTIL option though.

[Uncharted Fields @UnchartedFields]

Jose Fermin (26, UTIL) is one of my favorite under-the-radar utility players. While he doesn't hit the ball that hard, his plate approach in a limited 60-AB sample looked excellent, leading to a .283/.377/.417 MLB slash. The AAA statcast numbers looked great too, where he had a 146 wRC+ in 293 PAs. With more walks than strikeouts in his MiLB career, Fermin is someone I see as an OBP forward utility option that might hit around .260/.365/.370 with 10 HRs and 20 SBs if given 500+ ABs.

[Uncharted Fields @UnchartedFields]

Braxton Fulford was hitting .282/.419/.518 in AAA prior to callup a few weeks ago. The batted ball data regressed a bit compared to last year and some contact issues remain, but still someone I'm tracking for now. Combined with a brief 2-game stint in March, he's hitting .188/.278/.375 across just 16 ABs.

[Uncharted Fields @UnchartedFields]

Braxton Fulford (26, C) didn't do much in his 120 PA debut this year, but looked unreal in the hitter-friendly PCL, hitting .354/.433/.714 in 171 AAA PAs. It was a noticeable uptick from a .753 OPS in 92 AA games, but the batted ball data supported the AAA numbers. Fulford appears to have the leg up on Romo for the backup C spot and will look to make more of an impact with the bat in 2026.

[Uncharted Fields @UnchartedFields]

Although hurt from a May 5th toe fracture, Luis Campusano's bat finally seems to have caught up with MLB pitching. In 52 ABs before his injury, he was hitting .288/.362/.596. We'll see how he holds up in his return, but for now it seems the '25 AAA statcast data wasn't a fluke.

[Uncharted Fields @UnchartedFields]

Luis Campusano (27, C) did get around a dozen 1B reps in AAA, but otherwise is a bat-first C that has mostly struggled over parts of 6 MLB seasons. Hit .336/.441/.595 in 475 AAA PAs though and had elite batted ball data. Out of options, he might need an offseason trade to get a real shot at meaningful ABs.

[Uncharted Fields @UnchartedFields]

Ryan Vilade is also having a great start this year, hitting .318/.390/.485 in 66 ABs. While mostly used against lefties (.914 OPS, 47 ABs), he's actually hit well against RHPs too (.812 OPS, 19 ABs). It's a small sample size but his batted ball data in AAA last year was strong across the board.

[Uncharted Fields @UnchartedFields]

Ryan Vilade (26, OF) was recently acquired by the Rays and could filter into the OF mix next year. A bit of a journeyman already, Vilade hit .290/.378/.511 in 113 AAA games between the STL and CIN orgs. Vilade's batted ball data took a step forward this year though and the Rays often do a good job on identifying overlooked talent + platooning their hitters appropriately.

[Uncharted Fields @UnchartedFields]

Checking in on a few offseason targets, TJ Rumfield has had an excellent MLB debut with the Rockies, hitting .284/.357/.453 with 7 HRs and 27 RBIs across 190 ABs. Statcast data backs up the performance as well.

[Uncharted Fields @UnchartedFields]

TJ Rumfield (25, 1B) is someone to watch closely this offseason, as he's Rule 5 eligible if the Yankees don't add him to the 40-man. He put up very similar numbers in '24 and '25 at AAA (.826 OPS vs .825), although he did cool off in the second half this year. With a great plate approach and strong numbers vs. RHPs, the lefty would likely get a shot as a strong side platoon 1B on a team like the Rockies. If left unprotected, that might just happen.

[Uncharted Fields @UnchartedFields]

Raudi Rodriguez (22/AA/LAA) is batting .308/.440/.481 this year, which includes a 1.078 OPS in May thus far. He now has 5 HRs and 16 SBs (3 CS) on the season. The BABIP is running a bit high at .371, but an 18% walk rate and 19.2% K-rate highlight his strong plate approach.

[Uncharted Fields @UnchartedFields]

Raudi Rodriguez (22/A/LAA) is having a great Arizona Fall League thus far, hitting .471/.571/.706 through his first 43 PAs. Rodriguez had a breakout low-A season, putting up an .842 OPS with 14 HRs, 38 SBs (6 CS), and a strong 11.3 BB% / 23.2 K%. Rodriguez jumped on radars after an excellent August in which he hit .434/.529/.646 in 99 ABs. There's a good chance he debuts in AA to start next season.
