Final answer:
The Oakland A's implemented Moneyball, a strategy reliant on the use of sabermetrics, to manage their team and succeed in reaching the playoffs.
Step-by-step explanation:
The Oakland A's used a strategy known as Moneyball to manage the team and carry them to the playoffs. This approach was based on the analysis of sabermetrics, which is the empirical analysis of baseball statistics that measure in-game activity. Moneyball focused on undervalued aspects of players, such as on-base percentage, rather than more traditional statistics like batting averages, to build a competitive team despite a relatively low budget. This strategy was significant in modern baseball for featuring a data-driven approach to team assembly and player evaluation.
