MLB Week 1: 5 Series to Watch – Yankees-Mariners, Dodgers-Guardians & More

by Liam O'Connor Sports Editor

The first full week of the 2026 Major League Baseball season is already shaping up to be a compelling one, with several series promising high-stakes matchups and intriguing storylines. From a rematch between last year’s MVP contenders to potential playoff previews, fans have plenty to look forward to as teams begin to define their identities. This week’s schedule offers a blend of divisional rivalries and interleague clashes, providing a comprehensive look at the league’s evolving landscape. Following the exciting opening weekend, several series stand out as must-watch events for baseball enthusiasts.

One of the most anticipated series of the week features the New York Yankees traveling to Seattle to face the Mariners. The Yankees, consistently among the league’s elite, will be looking to continue their dominance over Seattle, having won five of six meetings in 2025 and outscoring the Mariners 40-23. This series isn’t just about team success; it’s a personal duel between two of the game’s brightest stars.

Yankees vs. Mariners: A Battle of MVP Caliber

The head-to-head matchup between Yankees slugger Aaron Judge and Mariners catcher Cal Raleigh is a central narrative. Judge narrowly edged out Raleigh for the 2025 American League MVP award, securing his third career MVP honor. Judge has started the 2026 season strong, already showcasing his power with multiple home runs. The two players share a recent history, having been teammates on the United States team that fell to Venezuela in the 2025 World Baseball Classic. Their competitive spirit and mutual respect promise a captivating series.

However, the star power doesn’t complete there. The Mariners boast a potent offense led by Dominican outfielder Julio Rodríguez, a perennial MVP candidate known for his exceptional defense and blend of power and speed. Alongside Rodríguez, players like Josh Naylor, Cuban outfielder Randy Arozarena and Brendan Donovan contribute to a Mariners lineup that could be one of the best in baseball. The Yankees, meanwhile, return with a largely unchanged roster that was the league’s most productive offense in 2025.

Dodgers Aim to Continue Dynasty, Guardians’ DeLauter Shines

Shifting to the National League, the series between the Cleveland Guardians and the Los Angeles Dodgers presents a compelling contrast in team trajectories. The Dodgers are aiming for an unprecedented third consecutive World Series title, a feat not accomplished since the New York Yankees’ run from 1998 to 2000. Their offseason acquisitions of Kyle Tucker and Puerto Rican closer Edwin Díaz have bolstered an already formidable roster. Tuesday’s game will be particularly noteworthy as Shohei Ohtani is scheduled to make his first start of the season.

The Guardians, however, are not to be underestimated. Rookie outfielder Chase DeLauter has burst onto the scene with a remarkable start to his career, hitting four home runs in his first three regular-season games – a feat only matched by Trevor Story in 2016. DeLauter’s emergence adds an exciting dimension to a Guardians team looking to contend in a competitive division.

Mets-Giants and Red Sox-Padres: Contrasting Fortunes

The series between the New York Mets and the San Francisco Giants presents a stark contrast in early-season fortunes. The Mets have started strong, winning two of their first three games, while the Giants were swept in a three-game series against the Yankees, managing to score only one run. The Giants face a challenging week, with a series against the Padres preceding their matchup against the Mets and Phillies.

At Oracle Park, fans will be watching to see if anyone can add their name to the list of hitters who have launched a home run into McCovey Cove. 108 balls have splashed down in the iconic inlet, with Dominican slugger Rafael Devers being the most recent to accomplish the feat on September 24, 2025. Mets stars Juan Soto and Francisco Lindor will be among those looking to join the exclusive club.

Finally, the Boston Red Sox will travel to San Diego to face the Padres. The Padres took two of three from the Red Sox last August, including a game decided by a walk-off hit from Dominican outfielder Ramon Laureano. The Red Sox will demand to contain the Padres’ offense, led by the red-hot Venezuelan outfielder Wilyer Abreu, who has homered in back-to-back games.

Brewers and Royals Showcase Speed and Defense

The Milwaukee Brewers’ series against the Kansas City Royals promises a showcase of athleticism and defensive prowess. Players like Bobby Witt Jr., Brice Turang, Maikel Garcia, and Sal Frelick are expected to deliver exciting plays and dazzling speed. Witt, in particular, is emerging as one of the most dynamic players in the game, and many anticipate he will reach another level of performance after finishing second in the 2024 AL MVP voting to Judge. For the Royals to return to playoff contention, another exceptional season from Witt will be crucial.

As the 2026 MLB season unfolds, these series represent just a glimpse of the compelling narratives that will emerge throughout the year. The coming weeks will undoubtedly provide further clarity on which teams are poised for success and which players are ready to take the next step. The next major checkpoint will be the end of April, when teams will have established a more substantial sample size and the competitive landscape will begin to take clearer shape.
