The city constructed a waterfront stadium for its new team, appropriately called Lane Field, replacing a race track that was on the site.
The team finished second in its inaugural year in the border city, then won the postseason series and the PCL pennant in 1937, led by the hitting of sophomore outfielder Ted Williams, who was first signed to a contract in 1936.
In 1954, managed by former major league player Lefty O'Doul, the Padres finished first in the PCL for the first time in their history, but were eliminated in the postseason playoffs.
Leishman, who had helped to run the Yankee farm system throughout the previous 10 years, was brought in with the goal of bringing the team to the Major Leagues.
Leishman was named general manager of the MLB Padres, with club president and minority investor Buzzie Bavasi, formerly GM of the Los Angeles Dodgers, playing a dominant role in its baseball operations.
