The alums of the Delco League read like a Who's Who in area baseball.

Phillies lefthander Jamie Moyer pitched in the Delco League.

So did Geoff Petrie, the NBA's Rookie of the Year in 1970-71.

Hall of Famer Frank "Home Run" Baker, of the old Philadelphia A's, played in the league in 1915.

The list is 100 years long.

Those players and the teams they played for will be honored tonight at the Drexelbrook, in Drexel Hill, in celebration of the 100th year of the league. The event is already sold out, with 570 tickets gone. The party begins with a social from 5:30 to 7 p.m., and then dinner from 8 to 9:30.

Expected guests include Hall of Fame pitchers Robin Roberts and Bob Feller. Other VIPs will include Dick Allen and Mickey Vernon, who will receive a special award for his tremendous support of the league.

"I think we have bragging rights as being the oldest incorporated league in America, and this Saturday, we'll start our 100th year," said Jim Vankoski, president emeritus of the Delco League, who served as president from 2001 to '06. "We're having a birthday party for the league. It's the achievement of the league that we're celebrating. Mickey is tremendous. He's a member of baseball royalty. We hope the rest of the nation knows how special the league is. Robin Roberts and Feller are coming here to celebrate with Mickey."

The Delco League provides a competitive outlet for college players and former pros who still want to play a high level of baseball. This year there are 10 teams and 250 players in the league.

The league has had as few as four teams and as many as 16 teams. It's that kind of adaptability that keeps it viable.

"I know a lot of very good players played in the league," said local baseball historian and author Rich Westcott. "It's 100 years old and one of the oldest baseball leagues in the world, along with the National and American leagues. I know in the past that they had some great teams. It's a great league and it's been a competitive league.

"As semipro leagues go, you can't have a more competitive league than the Delco League."
