A study by USAtoday.com showed which teams spent the most money in the MLB, all the way down to who spent the least. The article found that the top 3 teams that spent the most money were also the top 3 teams in the MLB and similarly, the bottom 3 teams happened to also spend the least amount of money. The money they spend has almost everything to do with the success of the team. 

If a salary cap was imposed, the MLB would become easier for the worse teams and harder for the better teams. The MLB would rely more on coaching and team chemistry than it would on getting heavy hitters such as Shohei Ohtani, Juan Soto, Zach Wheeler, Arron Judge and other  expensive players. 

Coach Remiker of the Cathedral Catholic Dons Baseball Team believes that if a salary cap was added to the MLB teams, it would level out the playing field for more teams in the MLB, granting a better chance to compete with big spender teams such as the Dodgers and Mets. Coach Remiker said that the Kansas City Royals and the San Diego Padres would be one of the teams to reach the top of the MLB if a salary cap was introduced where as the Rays who have a very small market would stay the same.

A graph from Fivethirtyeight.com proves that in recent history,  jumps in salary have been associated with larger gains in teams win percentage. Altogether, no teams out of the 20 teams with the highest  salaries since 1985 have finished below .500. This serves as crucial evidence that if a salary cap was applied to the MLB more teams would have a greater chance to compete with striving MLB teams with a chance to even overtake them.

In the MLB, teams rely on their owners to spend money getting star players, whereas in other sports like American football and basketball, teams have to rely on general managers to pick between players and coach them to their full potential.
