MLB 2026: Examining Each Team’s Biggest Weakness
As spring training unfolds and the 2026 MLB season approaches, teams have largely completed their offseason moves. But, despite the flurry of activity, most clubs still harbor at least one significant weakness that could hinder their performance. Let’s analyze the potentially fatal flaw for each MLB team, either unaddressed during the offseason or exacerbated by player departures.
American League
AL East
Baltimore Orioles
The Orioles bolstered their starting pitching with acquisitions like Shane Baz and Chris Bassitt , but still lack a definitive ace to lead the rotation. This has been a consistent need for the team.
Boston Red Sox
The departure of Alex Bregman leaves a void at third base for the Red Sox. Although Marcelo Mayer and Caleb Durbin will compete for the position, the loss of Bregman’s offensive and defensive contributions is substantial.
New York Yankees
Defensive struggles plagued the Yankees in the previous season, particularly at shortstop where Anthony Volpe led the American League with 19 errors . Improving defensive consistency will be crucial.
Tampa Bay Rays
The Rays’ lineup appears less potent heading into 2026, especially after trading Brandon Lowe. Beyond Junior Caminero, the team lacks hitters who consistently demonstrated significant power in the previous season.
Toronto Blue Jays
Losing Bo Bichette in free agency creates an offensive hole for the Blue Jays. While Kazuma Okamoto and Ernie Clement offer potential replacements, they are unlikely to match Bichette’s offensive output.
AL Central
Chicago White Sox
The White Sox struggled offensively in 2025, ranking 28th in MLB in OPS. The additions of Munetaka Murakami and Austin Hays are unlikely to fully resolve these offensive inefficiencies.
Cleveland Guardians
The Guardians’ lineup also underperformed, with the second-lowest OPS in MLB. The signing of Rhys Hoskins, while helpful, may not be enough to significantly elevate their offensive production.
Detroit Tigers
Baserunning was a weakness for the Tigers in 2025, finishing last in MLB in stolen bases. The team’s offseason acquisitions focused primarily on pitching, suggesting limited emphasis on improving baserunning.
Kansas City Royals
The Royals’ lineup lacked power in the previous season, ranking 26th in home runs. The team did not build substantial additions to address this deficiency during the offseason.
Minnesota Twins
Injuries have been a recurring issue for the Twins, impacting key players like Byron Buxton and Royce Lewis. Starting pitcher Pablo Lopez is expected to miss the 2026 season due to a UCL injury, further compounding this concern.
AL West
Athletics
While the Athletics boast promising young talent offensively, their pitching staff is a significant weakness. The starting rotation, led by Luis Severino and Jeffrey Springs, is considered one of the league’s weakest.
Houston Astros
Depth could be an issue for the Astros, who no longer appear to be consistent World Series contenders. The bottom half of their lineup lacks proven production, and injuries could expose this weakness.
Los Angeles Angels
The Angels’ bullpen was among the worst in MLB in the previous season, leading the league in blown saves with 34. The acquisition of Jordan Romano, who had a high ERA in his previous season, does not necessarily address this issue.
Seattle Mariners
The Mariners’ offense could benefit from reducing their reliance on home runs and decreasing their strikeout rate. They had the sixth-most strikeouts in MLB last season.
Texas Rangers
The Rangers’ bullpen was inconsistent in the previous season, tied for second in MLB with 29 blown saves. They lack a clear-cut closer for the 2026 season.
National League
NL East
Atlanta Braves
Injuries are already impacting the Braves before the start of the 2026 season, with Spencer Schwellenbach undergoing elbow surgery and Jurickson Profar receiving a season-long suspension.
Miami Marlins
The Marlins lack offensive firepower beyond breakout star Kyle Stowers. They ranked 27th in home runs in the previous season and may struggle to improve in that area.
New York Mets
The Mets’ bullpen remains a concern despite adding former Yankees relievers Devin Williams and Luke Weaver, both of whom had underwhelming seasons in 2025.
Philadelphia Phillies
The departure of Nick Castellanos leaves a hole in the Phillies’ outfield, which has been a weakness in recent seasons. Adolis Garcia, their replacement, had a disappointing previous season.
Washington Nationals
After trading MacKenzie Gore, the Nationals have one of the weakest starting rotations in MLB. Their ERA was second-worst in the league in 2025, and improvement seems unlikely.
NL Central
Chicago Cubs
Several Cubs hitters experienced significant declines in production during the second half of the previous season. Maintaining consistent performance throughout the year will be a key challenge.
Cincinnati Reds
While Eugenio Suarez’s return adds power to the Reds’ lineup, he also strikes out frequently, an area where Cincinnati struggled in the previous season.
Milwaukee Brewers
The Brewers face the challenge of replacing Freddy Peralta, their best starting pitcher. A younger arm will need to step up as the ace of the rotation.
Pittsburgh Pirates
The Pirates hit fewer home runs than any other team in MLB in 2025. The acquisitions of Brandon Lowe and Ryan O’Hearn may not be enough to address this power shortage.
St. Louis Cardinals
The Cardinals gutted their roster and are entering a rebuild, lacking veteran experience. Development of young players will be crucial, but growing pains are expected.
NL West
Arizona Diamondbacks
The Diamondbacks’ bullpen blew the third-most saves in MLB in 2025 and will be hampered by injuries to key relievers at the start of the 2026 season.
Colorado Rockies
The Rockies’ overall lack of talent is their biggest weakness. After a poor 2025 season, significant improvement seems unlikely.
Los Angeles Dodgers
The Dodgers’ primary concern is staying healthy. Injuries to their starting pitching rotation have been a recurring issue in recent years.
San Diego Padres
The Padres lack a true ace in their starting rotation, and both Michael King and Joe Musgrove have dealt with injuries. Depth in the rotation is also a concern.
San Francisco Giants
The Giants’ offense needs more consistent production. Only Rafael Devers had an OPS above .800 in the previous season, and the team ranked low in home runs, OPS, and slugging.
