Every MLB Team's Best Teenage Prospect in the Minor Leagues

San Diego Padres catcher Ethan Salas turned heads across baseball last season when he reached Double-A in his pro debut after signing for $5.6 million as the top prospect in the 2023 international class.

Who's next?

Ahead we've highlighted the best teenage prospect in every MLB organization, including Salas, who is still only 17 years old and sits firmly in the No. 1 spot in the Padres' organizational rankings.

Included is a look at where each player ranked on B/R's latest Top 100 prospect list, if applicable, and a quick scouting report on what they bring to the table.

The future of baseball is in good hands with this group of up-and-coming talent.

Baltimore Orioles: C/1B Samuel Basallo (Age: 19), No. 13 on B/R Top 100

One of the biggest breakout prospects of 2023, Basallo hit .313/.402/.551 with 26 doubles, 20 home runs and 86 RBI in 114 games while reaching Double-A shortly after his 19th birthday. He has a strong arm behind the plate, but his receiving skills are still raw, and he has started seeing more time at first base with Adley Rutschman blocking his path in the majors.

Boston Red Sox: SS Nazzan Zanetello (Age: 18)

The Red Sox signed Zanetello to an above-slot $3 million bonus as a second-round pick in the 2023 draft, and he has legitimate five-tool potential at shortstop. The biggest question mark is the development of his hit tool and whether he will fully tap into his plus raw power, but he has as much upside as any Red Sox prospect outside of Roman Anthony and Marcelo Mayer.

New York Yankees: SS Roderick Arias (Age: 19), No. 93 on B/R Top 100

The No. 1 prospect in the 2022 international class, Arias signed for $4 million and then hit just .194 in the Dominican Summer League in his pro debut. He made his way stateside last year and sent his stock soaring when he hit .267/.423/.505 with 10 extra-base hits and 17 steals over 27 games in rookie ball, and now he is diving into full-season ball at Single-A Tampa.

Tampa Bay Rays: RHP Santiago Suarez (Age: 19)

Suarez was acquired prior to the 2023 season in the deal that sent Xavier Edwards and JT Chargois to the Marlins, and he could follow in the footsteps of Junior Caminero and Curtis Mead as a low-level prospect pickup who emerges as a Top 100 guy. He already commands his three-pitch repertoire extremely well, giving him a high floor and MLB starter upside. He has a 4.72 ERA, 1.08 WHIP and a 34-to-2 strikeout-to-walk ratio over 34.1 innings at Single-A Charleston to start the year.

Toronto Blue Jays: SS Arjun Nimmala (Age: 18)

Nimmala had arguably the highest ceiling in a deep class of high school shortstops last spring, and the Blue Jays scooped him up with the No. 20 overall pick in the 2023 draft. He is still working to fully tap into his loud raw power, and maximizing that tool will be the key to delivering on his upside. He is off to a slow start at Single-A, hitting .167 with 43 strikeouts in 29 games, but his physical tools still give him Top 100 prospect potential in the near future.

Chicago White Sox: OF Samuel Zavala (Age: 19)

Zavala put himself on the top prospect radar when he made his Single-A debut in his age-17 season. He then hit .243/.391/.406 with 23 doubles, 14 home runs, 77 RBI and an impressive 93 walks in 115 games between Single-A and High-A last year before the White Sox acquired him during the offseason in the deal that sent Dylan Cease to San Diego. He could be the center fielder of the future on the South Side if Luis Robert Jr. becomes a trade chip.

Cleveland Guardians: OF Jaison Chourio (Age: 18), No. 97 on B/R Top 100

Chourio is the younger brother of Brewers rookie Jackson Chourio, and he is quickly making a name for himself in the prospect world. With a 60-grade hit tool, good speed and the defensive chops to stick in center field, he has developed into one of the Guardians most promising up-and-comers. He has an .812 OPS with more walks (29) than strikeouts (22) in 33 games at Single-A.

Last year's top draft pick Ralphy Velasquez is another teenager worth knowing with a 55-hit, 55-power offensive profile.

Detroit Tigers: OF Max Clark (Age: 19), No. 27 on B/R Top 100

Clark hit .646/.808/1.215 during his senior year of high school to win 2023 Gatorade National Player of the Year honors, and the Tigers took him No. 3 overall as part of a strong top tier of prospects in the 2023 draft class. He is hitting .250/.360/.320 with 10 steals and a 15 percent walk rate at Single-A, though he has just five extra-base hits in 153 plate appearances and is still working to get to his in-game power.

Kansas City Royals: C Blake Mitchell (Age: 19), Next 50 on B/R Top 100

The top prep catcher in the 2023 draft class, Mitchell went No. 8 overall and signed a below-slot deal, allowing the Royals to go above slot to sign pitcher Blake Wolters in the second round. He has an .816 OPS with seven doubles, four home runs, 13 RBI and 10 steals in 33 games at Single-A, and he also has a rocket arm behind the plate that delivered 97 mph fastballs off the mound as a two-way player in high school.

Minnesota Twins: OF Walker Jenkins (Age: 19), No. 20 on B/R Top 100

Jenkins hit .362/.417/.571 with 12 extra-base hits in 26 games between rookie ball and Single-A after going No. 5 overall in the 2023 draft, immediately putting himself alongside Brooks Lee and Emmanuel Rodriguez as the headliners in the Minnesota farm system. With a 60-hit, 60-power offensive profile and a strong 6'3", 210-pound frame he looks the part of a future middle-of-the-order run producer.

Houston Astros: 3B Waner Luciano (Age: 19)

Signed for just $45,000 in 2022, Luciano made his stateside debut in 2023 and posted an .821 OPS with 10 home runs and 29 RBI in 45 games. He doesn't provide much secondary value beyond his bat and he's off to a slow start at Single-A this year, but his elite exit velocity numbers are enough to make him the most intriguing teenager in a thin Houston system.

Los Angeles Angels: OF Nelson Rada (Age: 18), Next 50 on B/R Top 100

Rada emerged as the best position-player prospect in the Angels system last year when he hit .276/.396/.346 with 21 extra-base hits, 55 steals and a 13.5 percent walk rate in 115 games at Single-A. The Angels jumped him straight to Double-A to begin the 2024 season, and he is holding his own as one of the youngest players in the Southern League.

Oakland Athletics: RHP Steven Echavarria (Age: 19)

The A's gave Echavarria a $3 million signing bonus—roughly the slot value of the No. 26 overall pick—at No. 72 overall in the third round of the 2023 draft, luring him away from a commitment to the University of Florida. He has an advanced feel for his four-pitch repertoire, especially for a prep pitcher from a cold-weather state, and room to grow into his 6'1", 180-pound frame.

Seattle Mariners: SS Colt Emerson (Age: 18), No. 44 on B/R Top 100

Part of a loaded 2023 prep shortstop class, Emerson was also an all-state wide receiver in football, and his athleticism plays well at the middle infield spots. He hit .374/.496/.549 in 24 games between rookie ball and Single-A in his pro debut, and he is off to a strong start back at Single-A to begin the 2024 season.

Shoutout to slugger Lazaro Montes (19), touted shortstop Felnin Celesten (18) and 2023 draft picks Jonny Farmelo (19) and Tai Peete (18), as the Mariners have baseball's best collection of teenage prospects.

Texas Rangers: SS Sebastian Walcott (Age: 18), No. 79 on B/R Top 100

With an extremely projectable 6'4", 190-pound frame, elite bat speed and top-tier exit velocity numbers, Walcott has the potential to develop into a perennial 30-homer slugger at the next level. He is more raw tools than production at this point and hitting just .186/.309/.297 with a 28.8 percent strikeout rate at High-A Hickory, but if everything clicks he has superstar upside.

Atlanta Braves: SS Jose Perdomo (Age: 17)

In an Atlanta system thin on position-player prospects, Perdomo has a chance to quickly rise to the top of the heap. His $5 million signing bonus in January was the largest given to any player in the 2024 international class, and with a 55-grade hit tool and good overall polish to his game, he could be one of the stars of the Dominican Summer League this year.

Miami Marlins: RHP Noble Meyer (Age: 19), No. 61 on B/R Top 100

The Marlins walked away with arguably the top two high school pitching prospects in the 2023 draft class when they chose Meyer (No. 10 overall) and Thomas White (No. 35 overall) with their first two selections. Meyer is the more polished of the two and he is off to a strong start at Single-A with a 2.79 ERA and 32 strikeouts in 29 innings while holding opposing hitters to a .163 average.

New York Mets: SS Colin Houck (Age: 19)

A 3-star quarterback recruit in football, Houck also won Georgia Gatorade Player of the Year honors in baseball last spring before going No. 32 overall in the 2023 draft. His 6'2", 190-pound frame and strong arm could ultimately fit better at third base once he fills out, but his 55-hit, 55-power offensive profile should make him a clean fit at the hot corner.

Philadelphia Phillies: SS/3B Aidan Miller (Age: 19), No. 40 on B/R Top 100

One of the older high school prospects in the 2023 draft class, Miller will already be 20 years old on June 9 which puts some pressure on him to advance quickly through the Philadelphia farm system. The No. 27 overall pick last June is hitting .326/.425/.558 with 10 doubles, four home runs and 17 RBI in 24 games at Single-A, so he could be in line for an early promotion this spring.

Shortstop Starlyn Caba (18) also moved onto the Top 100 list in B/R's latest update.

Washington Nationals: OF Cristhian Vaquero (Age: 19)

The Nationals shelled out $4.925 million to sign Vaquero as one of the top prospects in the 2022 international class, and his 55-power, 70-speed profile speaks to his intriguing overall athleticism. He posted a .742 OPS with 15 extra-base hits and 22 steals in 58 games between rookie ball and Single-A last year, but he still has a long way to go in his development, specifically with making more consistent contact.

Chicago Cubs: SS Jefferson Rojas (Age: 19), No. 87 on B/R Top 100

Rojas hit .268/.345/.404 with 22 extra-base hits and 13 steals in 70 games as an 18-year-old at Single-A Myrtle Beach last year, showcasing his advanced hit tool and solid approach at the plate. It speaks volumes that he pushed Cristian Hernandez to second base when he arrived at Single-A in 2023.

Cincinnati Reds: 3B Cam Collier (Age: 19), No. 91 on B/R Top 100

Collier finished high school early and enrolled at JUCO powerhouse Chipola College before going No. 18 overall in the 2022 draft as one of the youngest players in his class. He hit .246/.349/.356 with 29 extra-base hits in 111 games at Single-A last year, and he didn't turn 19 years old until November. He has just scratched the surface of his offensive potential.

Milwaukee Brewers: OF Luis Lara (Age: 19)

Lara signed for $1.1 million in 2022 and jumped over rookie ball straight to Single-A in his stateside debut last year. With a 5'8", 155-pound frame he does not possess much present or future power potential, but his 55-hit, 60-speed profile could make him a top-of-the-order table-setter and he has a great chance of sticking in center field.

Pittsburgh Pirates: 2B Termarr Johnson (Age: 19), No. 85 on B/R Top 100

Johnson was hyped as "one of the best high school hitters in recent memory" when he was taken No. 4 overall in the 2022 draft, but it's his on-base ability that has driven his offensive value so far. He hit .244/.422/.438 with 101 walks in 105 games between Single-A and High-A last year, and he still has significant untapped power potential.

St. Louis Cardinals: RHP Branneli Franco (Age: 17)

The consensus top pitching prospect in the 2024 international class, Franco signed for $800,000 in January. He just turned 17 years old in February and still has significant room to add strength to his 6'3", 187-pound frame. His fastball currently sits in the low 90s with good late life, and he has also shown a plus curveball and changeup. He is a developmental prospect, but one with considerable upside.

Arizona Diamondbacks: IF Jansel Luis (Age: 19)

After a solid stateside debut in 2023, Luis is off to a strong start at Single-A Visalia with a .276/.327/.386 line and 12 extra-base hits in 34 games. The 2022 international signing has significant raw power potential and it should start to show up more in games as his 6'0", 170-pound frame fills out. He has seen time at both middle infield spots, but might be a better fit at second base with an average arm.

Colorado Rockies: OF Robert Calaz (Age: 18)

Calaz signed for $1.7 million in 2023 and posted a .984 OPS with seven home runs and 29 RBI in 43 games as one of the top hitters in the Dominican Summer League last year. The 6'2", 202-pound outfielder has continued to impress in stateside rookie ball, hitting .366/.447/.732 with three doubles, three triples, two home runs and three steals through 11 games. He has legitimate Top 100-prospect upside.

Los Angeles Dodgers: OF Josue De Paula (Age: 18), No. 71 on B/R Top 100

De Paula might have the highest offensive ceiling of any prospect on this list with a 60-hit, 55-power profile and a solid track record of production in 2022 and 2023.

"With his hitting ability, bat speed and projectable strength, he could develop into a .300 hitter with 30 homers on an annual basis once he learns to drive balls in the air more consistently," wrote MLB.com.

San Diego Padres: C Ethan Salas (Age: 17), No. 9 on B/R Top 100

A potential generational talent behind the plate, Salas made his pro debut as a 16-year-old at Single-A Lake Elsinore. He earned promotions to High-A and Double-A before the year ended, and he finished with a .248/.331/.421 line that included 13 doubles, nine home runs and 41 RBI in 66 games.

Leodalis De Vries signed for $4.2 million as the top prospect in the 2024 international class, and he could fly up Top 100 lists in the coming years.

San Francisco Giants: 1B Bryce Eldridge (Age: 19), No. 70 on B/R Top 100

The best two-way prospect in the 2023 draft class, Eldridge is now focusing exclusively on hitting as a first baseman with a 50-hit, 60-power offensive profile. The towering 6'7", 223-pound slugger is hitting .265/.327/.480 with six doubles, five home runs and 25 RBI in 25 games at Single-A San Jose, and pitching remains an intriguing fallback option as he featured a 96 mph fastball and a plus slider.
