Overview and Background of the Designated Runner System
The designated runner system was a special rule in NPB that allowed specific players to be registered as pinch-running specialists and deployed during games solely for base-running purposes. This system was conceived as a mechanism to leverage player specialization, similar to the DH (designated hitter) system. In the 1980s Pacific League, various experimental rules were introduced with the aim of energizing games and increasing attendance. The designated runner system was part of this initiative, with fleet-footed players serving as pinch runners, driving games through stolen bases and advancement to scoring position. This system officially recognized the existence of players specializing in base running, one element of baseball, representing a pinnacle of baseball's professional specialization. However, the system's operation was complex and sparked debate about game fairness.

The Achievements of Base-Running Specialists
Under the designated runner system, players specializing in base running demonstrated their unique presence. While they did not reach first-team level in batting or fielding, they contributed to games with their blazing speed of sub-6-second 50-meter dashes and excellent base-running judgment. Entering as pinch runners, executing stolen bases, and converting into runs, their role was limited yet crucial in deciding outcomes during close late-game situations. The existence of designated runners reaffirmed the value of speed in baseball. Amid a growing emphasis on batting, they proved that base running as a skill held independent value. However, designated runners' careers were unstable. Since batting and fielding abilities were not required, they constantly faced the risk of being released once their speed declined. Their playing careers were short, and second-career issues were serious.
Problems with the System and the Path to Abolition
Operational problems with the designated runner system gradually became apparent. The biggest issue was that the system could undermine game fairness. Since designated runners did not need to bat, they were evaluated solely on running ability. This drew criticism for contradicting baseball's fundamental principle of competing on the combined strength of batting, fielding, and running. There were also concerns that designated runner deployment overly complicated tactics and slowed game tempo. Furthermore, tactical imbalances arose between teams that utilized the system and those that did not, questioning league-wide fairness. In response to these issues, NPB proceeded with system review and ultimately abolished it. The abolition decision signaled a return to baseball's essence and an emphasis on players' comprehensive abilities.

Post-Abolition Base-Running Culture and Modern Impact
Even after the designated runner system's abolition, the importance of base running has not been lost in NPB. Rather, the system's existence heightened attention to base running as a skill, contributing to the subsequent development of base-running culture. In modern NPB, base running is positioned as an important element of comprehensive player evaluation. Beyond stolen base counts, metrics such as advancement rate and base-running runs (BsR) have gained attention, enabling multi-faceted evaluation of base-running value. The designated runner system is remembered as one of NPB's experimental rules. The experience of this system serves as a lesson demonstrating the need to carefully examine the impact of rule changes on competition. Baseball rules are built on the balance of three elements: competitive fairness, player ability expression, and fan enjoyment, and the rise and fall of the designated runner system illustrates the difficulty of maintaining that balance.
