With Biggio's son being called up and Vlad's son in the Majors, I wonder if more than two sons of Hall of Famers have ever played MLB at the same time.
Mariano Rivera's son Mariano III never made it past high-A ball and recently retired.
Are there any other Hall of Famers' sons who are top prospects?
Tony Gwynn's son Tony Jr. and Tony Perez's son Eduardo both played in 2006.
Tim Raines' son Tim Jr. also played at the same time as Eduardo Perez, but not with Gwynn Jr.
Other Hall of Famers who had Major League sons were Yogi Berra, George Sisler, Earl Averill, Eddie Collins and a few other old-timers.
