There is a disturbing mistake being repeated in wake of the devastating injury that has occurred to Stephen Strasburg. It has been reported and commented that Jim Riggleman was responsible for Mark Prior's injuries.
Please note that Jim Riggleman managed the Chicago Cubs from the 1995 season to the end of the 1999 season. Mark Prior pitched for the Cubs from 2002-2006. Dusty Baker managed Prior from 2003 to 2006.
As Annie Savoy would say, "You can look it up."
