The Rise of the Six-Man rotation: A Strategic response to Modern Baseball
The Los Angeles Dodgers are poised to implement a six-man starting rotation in 2025, a strategy influenced by the return of several pitchers from injury and the success of dual-threat stars like Shohei Ohtani and Yoshinobu Yamamoto in Japan. This move reflects a growing trend across Major League Baseball, with teams like the Boston Red Sox and New York Mets also considering adopting this approach. While Lucas Giolito of the Red Sox has expressed reservations, the Orioles, Nationals, Mariners, Phillies, Astros, and Angels, among others, have already experimented with six-man rotations in recent years.
This shift towards a larger starting pitching staff might seem counterintuitive at a time when pitcher health is a paramount concern. However, the trend is gaining momentum for several reasons, some of which are already evident in the league’s data.
The Changing Landscape of Pitching Rest
In recent years, there’s been a noticeable shift in the frequency of pitching starts with five days of rest compared to four. In 2021, starts with five days of rest surpassed those with four for the first time, a trend that continued in 2023 and 2024. This suggests a growing preference for extended rest periods between starts.
Several theories attempt to explain this shift. Some argue that increased rest helps prevent injuries, while others believe it leads to improved performance. A larger starting rotation could also alleviate the workload on relievers and allow teams to avoid moving starters to the bullpen.
The Impact of a Longer Season
Another factor contributing to the rise of the six-man rotation is the sheer length of the modern baseball season.
Historically, teams played 154 regular season games followed by a World Series that often began before September ended. For instance, the 1954 World Series champion New York Giants played a total of 158 games, concluding on October 2nd. They then enjoyed 193 days of rest before the start of the following season.
In contrast, the 2024 World Series champion Dodgers played 178 games, including a month-long expanded playoff format. They will have only 139 days of rest before their 2025 season opener in Tokyo, or 148 days before Opening Day in the United States.
Furthermore, the 2024 Dodgers threw 1,582.2 innings, substantially more than the 1,427 innings pitched by the 1954 Giants, despite having 54 fewer days to recover.
Preparing for a Grueling Postseason
Modern teams must also consider the possibility of navigating four rounds of playoffs, a scenario unknown to legendary pitchers like Sandy Koufax. This grueling postseason schedule adds another layer of complexity to pitching management, making a larger and more rested starting rotation a strategic advantage.The six-man rotation is not merely a passing fad; it’s a strategic response to the evolving demands of modern baseball. As teams prioritize pitcher health, performance, and postseason preparedness, this trend is likely to become increasingly prevalent in the years to come.
The evolution of Starting Pitcher Rest: A Look at Baseball’s Changing Landscape
The modern baseball landscape is a far cry from its early days. With expanded playoffs,a worldwide designated hitter,and an emphasis on power hitting,the demands on pitchers have never been greater. One meaningful change is the shift in starting pitcher rest patterns, a trend that reflects the sport’s evolution.
Imagine the potential impact of extending playoff rounds to their maximum length. That could mean an additional 22 games, translating to nearly 200 more high-pressure innings for pitchers, with significantly less time for recovery. This, coupled with other changes like the rise of the home run hitter and the relentless pursuit of velocity and spin, puts immense strain on pitching arms.
To understand the current situation, we need to look back at how we got here. A graph illustrating the percentage of starts based on rest time reveals a captivating story of baseball’s transformation.
Before 1960, the data is scattered, reflecting a time when baseball was a diffrent game. Doubleheaders were commonplace, and teams often employed unconventional pitching rotations. The concept of a “starting rotation” was much more fluid.
For much of the 20th century, starting on five days’ rest, the standard for a six-man rotation, was relatively uncommon. Two days’ rest was the norm, with starts distributed fairly evenly across various rest periods except for five days.
while it’s challenging to make direct comparisons due to the evolving nature of the game,it’s worth noting that even legendary teams didn’t always rely on a handful of workhorses. The 1955 World Series champion Brooklyn Dodgers, for example, utilized seven starters with at least 10 starts each, with only one exceeding 200 innings.
Fast forward to the mid-1970s, a period marked by expansion, a longer regular season (162 games), and the addition of a playoff round. This era saw the shift from a four-pitcher to a five-pitcher rotation, leading to a decline in starts on two or three days’ rest.The dominance of the five-pitcher rotation continued until the late 1990s and early 2000s, when further expansion and the introduction of the Wild Card playoff spot began to change the landscape. By 2012,with the addition of a second Wild Card,starts on five days’ rest dipped below 50% for the first time in decades.
The trend of increased rest for starting pitchers is undeniable. As the game continues to evolve, it will be engaging to see how this trend impacts pitching strategies and the overall balance of the sport.
The Six-Man Rotation Debate: More Rest, More Questions
The MLB’s expansion to a 12-team postseason format in recent years has reignited the debate surrounding pitching rotations. while the trend towards larger rotations had been brewing for some time, this change marked a significant shift.
But does a six-man rotation actually benefit pitchers? The answer remains elusive, despite numerous studies attempting to decipher its impact. Research from outlets like FiveThirtyEight, Baseball Prospectus, and FanGraphs has yielded inconclusive results, leaving the question open for discussion.
One compelling argument in favor of the six-man rotation lies in its alignment with practices in other high-level baseball leagues. In Japan, as an example, starting pitchers typically take the mound once a week. This pattern isn’t unique to Japan; Minor League Baseball starters also enjoy more rest days compared to their Major league counterparts.
In 2022, a mere 10% of Minor League starts occurred with five days’ rest or less. As one anonymous former Major League pitcher pointed out, the transition from a six-day rotation in the Minors to a five-day rotation in the Majors can be jarring for young pitchers.
The “Friday night starter” tradition in college baseball further supports the argument for increased rest. This coveted role,typically reserved for a team’s ace,often involves pitching once a week,allowing for ample recovery time. paul Skenes, the 2024 National League Rookie of the Year, exemplifies this pattern.During his final season at LSU in 2023, Skenes made 19 starts, with the first 18 coming after six, seven, or eight days of rest. His lone start with less rest occurred during the College World Series finals, highlighting the prioritization of rest even in high-stakes situations.
Upon joining the Pirates,Skenes continued to pitch on five days’ rest or more,demonstrating a consistency in approach across different levels. Though, comparing pitchers across different levels and talent pools complicates the analysis. Skenes’ exceptional performance skews the data,making it challenging to draw definitive conclusions about the overall impact of increased rest on starting pitchers.
While anecdotal evidence suggests that adjusting to a different pitching schedule at the highest level of competition might not be ideal, concrete data remains scarce.The perspectives of team managers further illustrate the complexity of the issue. James Click, former Astros general manager, expressed the hope of extending pitchers’ workloads and reducing bullpen strain through a six-man rotation. Conversely, Phillies manager Rob Thomson highlighted the increased pressure on the bullpen resulting from a six-man rotation due to the reduced number of available relievers.
Adding another layer of complexity is the 2021 expansion of MLB rosters to 26 players. This change introduces additional factors to consider in the dynamic interplay between starting rotations and bullpen usage.
Furthermore, implementing a six-man rotation isn’t a one-size-fits-all approach. Teams can tailor their rotations to suit their specific needs. Such as, a team might opt to maintain a four-day rest schedule for their top starters while allowing the rest of the rotation to pitch on five days’ rest. This flexibility allows teams to experiment and find the optimal balance for their pitching staff.
The Evolution of Starting Pitcher Rest: A Shift Towards Longevity
The traditional model of a five-man starting rotation, with pitchers taking the mound every fifth day, is facing a gradual transformation. While not universally adopted, a growing number of teams are experimenting with extending rest periods for their starters, pushing them to pitch every sixth day instead. This shift is driven by a combination of factors, including the increasing demands of a longer baseball season and a greater emphasis on pitcher health and longevity.
While some traditionalists, like Cole Hamels who voiced his preference for the five-day rotation in 2018, may resist this change, the trend is gaining momentum. Historically, even the shift from four-day rotations to five-day rotations likely faced opposition from pitchers accustomed to the older model.
This new approach to pitcher usage isn’t necessarily a permanent fixture for every team. It could be strategically implemented during specific stretches of the season, particularly when the schedule is packed with games and pitchers need extra recovery time.
The data supports this evolving landscape. For the past three out of four seasons, the traditional model of five starters consistently pitching every fifth day hasn’t been the dominant strategy. This suggests that the six-day rotation, or variations of it, might become even more prevalent in the coming years.
One of the most compelling reasons behind this shift is the sheer volume of baseball being played. With an expanded regular season and the potential for deep playoff runs, pitchers are facing an unprecedented workload. Providing them with additional rest days helps mitigate the risk of injury and allows them to perform at their peak throughout the season.
