9. Cleveland Indians (2017)
The Indians were superb in 2017 and probably should have won the World Series. However, the Yankees had other ideas and stopped Cleveland in their tracks. Despite this, their regular season record was superb. At one point they rode one of the longest winning streaks in MLB annals. It was highly impressive because of the competitiveness of the modern era. It was arguably the greatest run ever (via ABC News).

According to ABC News, the odds of them completing this run were as low as 1 in 65,000. This is ludicrous but shows their level of commitment to winning. In the end, they ran out of gas and couldn’t sustain it in the World Series. But this doesn’t hide the fact that they were a superb team. It was also their best regular season in 43 years.
