Atlantic League of Professional Baseball

The Atlantic League of Professional Baseball (ALPB) is a professional independent baseball league in the United States. It is an official MLB Partner League based in the Mid-Atlantic and Southeastern United States, and the headquarters are located at Penn Medicine Park in Lancaster, Pennsylvania.

The Atlantic League mostly operates in cities that do not have Major League Baseball (MLB) or Minor League Baseball teams. Most of its teams are in suburbs and exurbs that are too close to other teams to have their own minor league teams. The Atlantic League requires cities to have ballparks that can hold between 4,000 and 7,500 people and meet Triple-A standards. When Atlantic League players join MLB teams, they usually start in Double-A or Triple-A teams.

The Atlantic League is considered the most successful and highest level of baseball among independent leagues. It is similar to the Double-A level. The Atlantic League has had many famous players, including Jose Canseco, Mat Latos, Steve Lombardozzi Jr., Francisco Rodríguez, Chien-Ming Wang, Roger Clemens, Rich Hill, Scott Kazmir, Juan González, Pablo Sandoval and Dontrelle Willis. Two former Atlantic League players are in the National Baseball Hall of Fame and Museum, Tim Raines and Rickey Henderson.

History

The Atlantic League of Professional Baseball started in 1998 with teams in places like Bridgewater, Newark, and Atlantic City in New Jersey. It was created because the New York Mets did not want to move a team from Albany-Colonie, so Frank Boulton started a new league with better pay and a longer season. The league wanted experienced players and better facilities.

In 2010, the league grew to Sugar Land, Texas, adding its first team not on the Atlantic coast. Over time, some teams left or changed names. In 2015, the league began using special baseballs with red and blue seams. In 2020, the league could not play its normal season because of the COVID-19 pandemic, but a few teams played in Texas. New teams joined later, like the Gastonia Ghost Peppers in 2024.

2020s

Because of the COVID-19 pandemic in 2020, the Atlantic League could not play its normal season. Some teams could not open their stadiums, so they held community events instead. Only two teams played that year. In 2021, a new team joined from Gastonia, North Carolina.

In 2021, the Somerset Patriots left to become a minor league team, and the Sugar Land Space Cowboys also joined a minor league. New teams like the Lexington Legends and Charleston Dirty Birds joined the league. In 2022, Kelsie Whitmore became the first woman to start and pitch in an Atlantic League game.

In 2023, the Hagerstown Flying Boxcars were named, and the Spire City Ghost Hounds took a break. The Gastonia Honey Hunters were removed due to debts, and a new team, the Gastonia Ghost Peppers, started playing in 2024.

Experimental rules

2019

In 2019, the Atlantic League tried new rules with Major League Baseball’s approval:

• Using a radar system to help umpires decide balls and strikes
• Shortening the time between halves of innings
• Requiring pitchers to face at least three batters
• Banning visits to the pitcher’s mound except for changes or medical reasons
• Limiting how players can position themselves in the infield
• Making bases bigger
• Moving the pitcher’s spot farther back

Some of these rules were delayed or changed later.

2021

In 2021, more new rules were tried:

• Changing how the ball-strike system worked
• A rule that if a team removes its starting pitcher, they can’t use a designated hitter for the rest of the game
• Moving the pitcher’s spot back farther for part of the season
• Raising player salaries to at least $13,800 per year

2022

In 2022, the Atlantic League stopped using some rules:

• The ball-strike system was no longer used
• The pitcher’s spot went back to its original distance

New rules were also announced for 2023:

• Changing the “double-hook” rule so teams keep their designated hitter if the pitcher throws at least five innings
• Allowing batters to run to first base on pitches not caught, getting a hit if they make it

2023

In 2023, three new rules were tested:

• A “designated pinch-runner” rule letting teams pick a runner to substitute in and later return
• Pitchers could only disengage once per at-bat, or it would be a balk
• Keeping the “double-hook” rule as changed in 2022

2024

In 2024, player salaries were raised to a minimum of $30,250 per year.
