The Pacific Coast League (PCL) is a Minor League Baseball league based in the Western United States. Like the International League, the PCL plays at the Triple-A (AAA) level, the most difficult level before Major League Baseball (MLB).
The league started in 1903 and was a popular baseball league in the region until 1958 when MLB teams moved there and MLB games began to be shown on television. It was named the Pacific Coast League because it started with only teams from the states of California, Oregon, and Washington, which are next to the Pacific Ocean. After MLB took control of Minor League Baseball in 2021, it was called the Triple-A West for one season before going back to the PCL name in 2022.
