Paul O'Neill - 1990 with the Cincinnati Reds and 1996, 1998, 1999, and 2000 with the New York Yankees.
Another player may be Luis Sojo who was with the Toronto Blue Jays in 1993 and the Yankees in 1996, 1998, 1999, and 2000. He is not listed as having played in the 1993 and 1998 World Series and I cannot find whether he was a member of the World Series roster during those two years.

Billy Hatcher of the Cincinnati RedsThe winner of the Babe Ruth award in 1990 was Billy Hatcher of the Cincinnati Reds.

The award is to honor baseball legend Babe Ruth, and has been awarded every year since 1949. (with the exception of 1994 when the World Series was canceled due to the players strike.)
