The Major League Baseball season is hitting its stride, and May has historically been a critical month for teams looking to establish momentum. The New York Yankees stand out with a .628 winning percentage in May over the past decade, leading the league. Following closely are the Houston Astros (.624) and Los Angeles Dodgers (.622), both of whom have recently secured World Series titles. The Tampa Bay Rays, with a respectable .561, round out the top four.

Interestingly, despite their current May success, several teams, such as the Yankees and Rays, have not captured a championship in years. The Astros and Dodgers, however, have made their marks with multiple titles since 2015, indicating that excellence in May can be a precursor to postseason success. Among the teams that have struggled, the Oakland Athletics have the worst record in May over the last decade at .409, underscoring the wide variance in team performance during this pivotal month.
