Introduction

As Major League Baseball gears up for the 2026 season, organizations are not only looking outward for talent but also focusing on in-house improvements. The offseason offers plenty of headlines with trades and signings, but the true game changers can often be found within each team’s current roster. Breakout performances can come from various player backgrounds, whether a rising prospect solidifies their role or an established player evolves into an All-Star. This article will spotlight one breakout candidate for each MLB team, looking exclusively at position players, while leaving pitchers for another discussion. Each player highlighted has already made their MLB debut and has yet to be selected for an All-Star team.

Baltimore Orioles: Samuel Basallo

At just 21 years old, Samuel Basallo is positioned to make a significant impact as the Orioles' starting designated hitter or backup catcher. Despite a rocky start in 2025 with a low .165 batting average, Basallo’s minor league stats paint a different picture. He boasted an impressive .966 OPS and hit 23 home runs at Triple-A. With elite bat speed, he has the potential to emerge as a middle-of-the-order run producer.

Boston Red Sox: Roman Anthony

Roman Anthony, another 21-year-old, could be a crucial piece for the Red Sox. In 2025, he displayed his talent through a robust .292 batting average and contributed to the team’s success with a .620 win percentage during his appearances. If he remains healthy, 2026 might see him earn his first All-Star selection as he continues to shine as a potential superstar.

New York Yankees: José Caballero

José Caballero will look to make a name for himself as the Yankees' starting shortstop, especially with Anthony Volpe sidelined. He showcased his speed by leading the American League in stolen bases and proved he deserves more playing time with a solid performance post-trade deadline.

Tampa Bay Rays: Justyn-Henry Malloy

Justyn-Henry Malloy, 25, will compete for a spot in the outfield after a modest MLB appearance last season. His strong minor league numbers show promise, and with potential opportunities arising from competition, he may finally break through in 2026.

Toronto Blue Jays: Ernie Clement

At 29 years old, Ernie Clement is primed to step into a full-time role at second base after excelling as a utility player. With impressive WAR numbers over the last two seasons and a strong postseason showing, he is positioned for a breakout season following the departure of Bo Bichette.

Chicago White Sox: Kyle Teel

With a promising start in his debut season, Kyle Teel is set to claim the starting catcher role for the White Sox. His strong performance down the stretch signals a bright future as he solidifies his place in the lineup.

Cleveland Guardians: George Valera

George Valera, recovering from injuries, stepped into the postseason and made a mark, suggesting he could take on a bigger role in the coming season. His minor league accolades elevate expectations for 2026.

Detroit Tigers: Colt Keith

Colt Keith emerges as a regular third baseman after a solid contribution in various positions throughout the past season. His growing walk rate and performance hint at significant improvements going forward.

Kansas City Royals: Jac Caglianone

Drafted in 2024, Jac Caglianone now has the chance to show his skills as the Royals’ starting right fielder. After stellar minor league success, fans are eager to see if he can translate that success to the MLB level.

Minnesota Twins: Matt Wallner

Despite a high strikeout rate, Matt Wallner has one of the most powerful bats in baseball. If he continues to get opportunities against lefties, he could post a 30-home run season.

Oakland Athletics: Denzel Clarke

Denzel Clarke, coming off an injury-shortened season, is expected to be the starting center fielder for the Athletics. His defensive skills coupled with minor league success could make for an impactful season ahead.

Houston Astros: Joey Loperfido

After impressing in a brief stint with the Astros, Joey Loperfido could earn a starting spot in left field this season, showcasing his ability in front of a new home crowd.

Los Angeles Angels: Nolan Schanuel

With adjustments to his offensive game, Nolan Schanuel is looking at a possible breakout season as the Angels’ starting first baseman. His strong on-base skills show promise as he steps into a more prominent role.

Seattle Mariners: Cole Young

Entering a positional battle at second base, Cole Young’s strong minor league track record could lead to significant improvements from his rookie numbers.

Texas Rangers: Evan Carter

Evan Carter gained playoff fame but faced injury setbacks in 2025. A full season could see him fulfill his promise as a top center fielder in the league.

Conclusion

The upcoming 2026 season holds promise for many MLB players ready to make their mark. With key breakout candidates across various teams, fans and analysts alike will be monitoring these individuals closely, as their performances may well shape their teams’ fortunes and potentially change the landscape of the league.
