Overview of the 2004 Red Sox First Base Situation
In 2004, the Boston Red Sox won their first World Series since 1903, and the role of first baseman was central to that success. The position was occupied primarily by Kevin Millar, with contributions from Sean Casey, Mike Lowell, and occasionally Dave Roberts over the course of the season. This article explains who played first base for the Red Sox in 2004, how each performer fit into the lineup and defensive scheme, and how that group helped carry Boston through the regular season and into postseason history.
Key First Basemen on the 2004 Red Sox
Kevin Millar
Kevin Millar was the everyday first baseman for much of the 2004 season, known for his steady defense, reliable bat, and clubhouse leadership. He provided consistent contact hitting and was a key part of the team’s culture as it chased a championship. Millar batted leadoff or in the top of the order and played a high volume of games at first base during the regular season.
Sean Casey
Sean Casey saw significant time at first base, especially in the middle of the season and during key stretches. Known for his approach at the plate and ability to hit for average, Casey offered a slightly different style than Millar while remaining a dependable option in the lineup.
Mike Lowell and Dave Roberts
Mike Lowell and Dave Roberts also saw action at first base, largely in late-game defensive substitutions and occasional starts. Lowell brought defensive versatility and occasional power, while Roberts contributed as a pinch-hitter and defensive replacement, particularly later in the season and into the playoffs.

In-Game Role and Batting Order Context
Millar typically batted leadoff or second, emphasizing getting on base and applying early pressure. Casey often batted third or fourth, leveraging his ability to move runners and drive in runs. Lowell and Roberts entered in defensive substitutions or as pinch-hitters, allowing manager Terry Francona to maintain defensive flexibility and match up favorably in late innings.
Postseason Performance and Clutch Contributions
During the 2004 postseason, the Red Sox leaned heavily on Millar and Casey at first base, with Roberts adding value as a pinch-hitter and defensive replacement. Notably, Roberts’ memorable pinch-hit single in Game 4 of the ALCS helped preserve a crucial lead. The depth provided by multiple first basemen allowed Boston to navigate a gruining playoff run without a pronounced drop in defensive stability or offensive production.
Why the 2004 First Base Depth Mattered
The flexibility to rotate and substitute at first base helped manage player fatigue, provided strategic matchups, and ensured defensive alignment could adjust from game to game. This approach exemplified the team-first philosophy that defined much of the 2004 season and contributed to one of the most memorable playoff runs in franchise history.
Summary of First Base Contribution in 2004
Throughout the 2004 season, the Red Sox relied on a blend of an everyday starter in Kevin Millar, steady contact hitters in Sean Casey, and versatile defenders like Mike Lowell and Dave Roberts. Their combined contributions supported both day-to-day performance and an unparalleled postseason journey. The first-base unit exemplified preparation, adaptability, and resilience, all of which were essential elements of the team’s historic championship campaign.
