COOPERSTOWN, N.Y. - Derek Jeter still has three games left before retiring, but Cooperstown officials already are thinking about his likely induction into the Baseball Hall of Fame.

The New York Yankees' shortstop will be eligible for enshrinement in 2020. For Cooperstown Mayor Jeff Katz, it's not too early to start planning for what would be a huge crowd.

Katz told WSTM-TV in Syracuse (http://bit.ly/1uM5M5N ) that the attendance that July weekend could top 100,000. When Tony Gwynn and Cal Ripken Jr. were inducted in 2007, about 80,000 jammed Cooperstown.

The mayor says Otsego County emergency services and state police will work with Hall of Fame officials to prepare for the 2020 induction weekend.

A big crowd is also anticipated in 2019 for former Yankees reliever Mariano Rivera's expected induction.
