While a member of the Giants, Melvin served as the backup for fellow catcher Bob Brenly, who also went on to serve as manager of the Diamondbacks. Later, Melvin became one of Brenly's bench coaches. Got a ring from the '01 squad.
Larry Rothschild is someone I've been aware of for quite some time. Got his start with the (then) Tampa Bay Devil Rays in their inaugural season in '98. Was the skipper there until '01 when none other than Sweet Lou replaced him. Hails from Chicago and has been the Cubs' pitching coach since 2002.
Currently works under Piniella. However, this isn't the first time he's worked under him. Was the Reds' bullpen coach from 1986-1993. Got a ring from the '90 squad with Lou. Also got a ring from the '97 Marlins squad. Will Rothschild and Piniella find the magic again? The Cubs faithful certainly hope so. But I wouldn't hold my breath.
