Introduction

With the 2025 MLB season approaching, the impact of the 2023 rule changes continues to shape the game. The pitch clock, larger bases, and restrictions on defensive shifts have created a new normal in baseball. This article delves into the statistical shifts, key trends, and their implications for fantasy baseball managers.

Key Rule Changes and Their Impact

• Pitch Clock Adjustments: The pitch clock was reduced from 20 to 18 seconds with runners on base, leading to shorter game times. In 2024, the average game time was 2 hours and 36 minutes, the shortest since 1984.
• Stolen Bases Surge: The new rules have incentivized base stealing. In 2024, 24 players stole at least 30 bases, the highest number since 1999. Elly De La Cruz led with 67 stolen bases, tying for the seventh-most in the 21st century.
• Pitching Specialization: Complete games are becoming rarer. The 2024 season saw the fewest complete games in MLB history (28), and only 5.1% of starts saw a pitcher face an opponent's lineup more than three times.

Statistical Trends and Fantasy Relevance

• Batting Averages & RBI: The league-wide BABIP remained steady at .291, and batting averages on pulled ground balls and line drives were consistent for both left- and right-handed hitters.
• Strikeouts and Velocity: MLB saw its highest average fastball velocity (94.2 mph) in 2024, contributing to the league’s 22.0% strikeout rate, the fourth-highest in history.

Player Highlights and Projections

Several players stood out in 2024, with Shohei Ohtani achieving a 50/50 season and Ronald Acuna Jr. setting a high bar with 73 stolen bases in 2023.

Advanced Strategies for Fantasy Managers

• Rotisserie Leagues: The value of stolen bases has shifted, with 30-SB performers bringing 51% greater value in 2024 compared to 2019.
• Points Leagues: Players like Jazz Chisholm Jr. and Brice Turang provided significant value through stolen bases, accounting for 12-15% of their total fantasy points.

Looking Ahead to 2025

While rule changes in 2025 are minimal, fantasy managers should prepare for trends like increased pitching velocity and the continued rise of stolen bases. Keeping an eye on advanced metrics like Statcast and defense-independent statistics will be crucial for success.
