Depth is something every organization tries to create, and it goes well beyond what we see at Target Field or in St. Paul. I’m researching the Twins’ depth beyond the 40-man roster, and have already taken a look at catcher, first base, and second base.
Third basemen often are shortstops who have moved over to the hot corner for one of many reasons. One might be that they outgrew the position, like Miguel Sano did, or that shortstop is no longer the best defensive fit, like Trevor Plouffe or Royce Lewis. That move comes with different expectations offensively: corner bats are often expected to have a better offensive profile than middle infielders.
Here is a list of third base prospects not on the Twins’ 40-man roster. I’ve included how and when they were acquired, along with the highest level they played this past season.
Tanner Schobel
Acquired: 2nd round, 2022 draft
Highest Level in 2025: Triple-A
If you follow the Twins’ drafting over the past few years, you’ll notice a pattern of selecting college-level bats higher in the draft. Schobel fits that profile. Drafted in the second round out of Virginia Tech in 2022, he hit for a 1.134 OPS over his final year with the Hokies. Since being drafted, Schobel has played at every level of the minors, reaching Triple-A St. Paul in 2025. While he struggled to a .651 OPS in his first taste of Triple-A, he is only 24 years old, and it is a small sample size of just 30 games. Prior to the call-up, he hit for a slash line of .292/.372/.465 at Double-A over 49 games, which earned him the call-up.
While on the list of third basemen, he has also shown the ability to play both second base and shortstop as well. The Twins love positional flexibility among players, so they are able to play matchups and put the best possible lineup out there on any given day. He’s a more contact-oriented hitter with the ability to hit some (nine in 2025) home runs. He’s a prospect with a high floor, and his defensive versatility will help him potentially carve out a role on the big league team, as long as he is able to continue making adjustments at the plate.
Billy Amick
Acquired: 2nd round, 2024 Draft
Highest Level in 2025: High-A
Another college bat drafted in the second round, Amick started his collegiate career at Clemson and then transferred to Tennessee for the 2024 season. Over his collegiate career, he had an OPS of 1.072 and hit 36 home runs over 120 games played, with 23 of those home runs coming in 2024 with the Volunteers.
Since being drafted, the 23-year-old hasn’t hit for that kind of power as he is making the adjustment to professional baseball, but he has gotten on base. In 2025, Amick played mostly at High-A Cedar Rapids, where he hit .310/.418/.455. He is a high strikeout player, striking out 63 times over 244 plate appearances, which will not be a problem if his power develops like many expect it will.
Amick played about half his time at first base and half his time at third base this past season, which means his offensive development will be even more important since first basemen are expected to hit. He was also selected to play in the Arizona Fall League in 2025, where he played in 11 games, and seven of them were at first base. He didn’t hit much in the Arizona Fall League, but it’s an extremely small sample size, so not too much to be worried about, especially for a player who hasn’t played above High-A professionally. He’s an intriguing prospect, but his bat will be what carries him. Keep an eye out to see if his power develops this coming season.
Danny De Andrade
Acquired: International Free Agency, 2021
Highest Level in 2025: High-A
Signed as an international free agent in 2021, De Andrade has been on the Twins ‘ prospect lists since then. He was signed as a shortstop, but played the majority of his games at second base and third base in 2025. De Andrade is still just 21 years old and played the past two seasons at High-A Cedar Rapids. In 2025, he hit for a .704 OPS, which was his first full season at High-A after only playing in 29 games in 2024 due to an injury. He has shown the ability to hit some (nine in 2025) home runs and steal some (15 in 2025) bases, so keep an eye on whether those things continue to happen as he moves up in competition. He is athletic enough to be a shortstop, but keep an eye on how often he is playing there versus elsewhere in the infield.
Jay Thomason
Acquired: 17th round, 2024 Draft
Highest Level in 2025: High-A
A later round pick in 2024, Thomason hit the cover off the ball in his collegiate career at the Air Force Academy. He hit for 1.122 OPS over his four seasons, with 58 home runs over 194 games played. A left-handed hitter, Thomason has shown solid plate discipline, taking a walk in 18.2% of his at-bats in 2025. This is likely due to lower minor-league pitchers having less effective control, and Thomason was playing his age-23 season in A ball.
While his walk rate will likely come down some in the minors, he has also shown some power, hitting for .477 slugging percentage this past season. Thomason has played not just third base, but also at first base, second base, and in left field as well in his short time in the minors. No matter where he ends up defensively, he is an intriguing prospect who has shown some flashes. We will see if he is able to continue developing as he faces higher competition and sneak his way into the Top 30 prospect discussion in the next year or so.
Rayne Doncon
Acquired: Trade, Los Angeles Dodgers, February 2024
Highest Level in 2025: High-A
You may recognize Doncon’s name as the prospect who came to the Twins along with Manuel Margot prior to the 2024 season. While Margot was not at the top of the list of acquisitions prior to the disappointing 2024 season for the Twins, Doncon was a lower-level prospect who was essentially a lottery ticket at the time. He has shown some power, but hasn’t developed offensively, hitting for a slash line of .183/.286/.299 in A ball in 2025. Still just 22 years old, he will be looking to bounce back this season and take a step forward in his development.
Quentin Young
Acquired: 2nd round, 2025 Draft
Highest Level in 2025: Single-A
Another name you might recognize, as he is the nephew of former Twin Delmon Young. A very different player, Quentin is 6’6” and 225 lbs. He was drafted as a shortstop, but he will likely end up moving to third base down the road, as you don’t see many shortstops that are that tall. He’s got huge raw power, but like many young (he’s 18 years old) hitters with power potential, has shown some swing-and-miss concerns as well. He only had 22 plate appearances last year in Fort Myers after signing. While a move to third is possible, there is a chance he is tried at other positions as well to see where he best fits defensively.
Ryan Sprock
Acquired: 8th round, 2025 Draft
Highest Level in 2025: Single-A
An 8th-round pick in 2025, Sprock ended up playing in 23 games with Fort Myers after being drafted. He played his college years at Elon, where he posted a .958 OPS over three seasons. In his final season with Elon, he hit 14 home runs over 57 games played, and hit two more with the Mighty Mussels after being drafted as well. While still very early in his development, he’s an intriguing mid-round prospect and someone to keep an eye on.
Yilber Herrera
Acquired: International Free Agency, 2022
Highest Level in 2025: Single-A
Signed as an international free agent in 2022, Herrera will be playing his age-21 season in 2026. In 2025, he moved up from the Complex League and played ten games at Single-A. He projects as a contact hitter, and the hope is that power will develop as he continues to mature. Signed as a shortstop, Herrera has been tried out mostly at second base and third base, but was also tried in the corner outfield for a few games this past season. His offensive development will be the key thing to watch this coming season.
Darwin Almanzar
Acquired: International Free Agency, 2025
Highest Level in 2025: Dominican Summer League
An international free agent signing just last year, he played in the Dominican Summer League, where he showed some promise, hitting for an .843 OPS with six home runs over 44 games played. Still very early in his development and playing his age-18 season in 2026, he is a long way from making an impact at Target Field. Almanzar remains a prospect to monitor periodically to see whether he continues to perform at a higher level as the competition increases.
