Got back two returns today....
Bobby was the regular second baseman for the California Angels in the 1960s. He and Jim Fregosi were a good combination.
Mike was listed on the spring training roster of the 1969 Seattle Pilots, though I can't find anything on BaseballReference.com regarding his pitching record. he also played basketball and baseball at the University of Florida in the mid 1960s
UPDATE 10/27/2012 Thanks to Keith Olbermann who informed me that "Rollyson never pitched an inning of pro ball. He was invited in by the
Pilots while still a student, and when he didn't make it, apparently he
went back to college! "
