34 Year-Old Rookie Article From 2010 Desert Valley Mountain Lions
Found an article on Checkswing.com about Barry Fowler who, at the time, was 34 years old as a rookie. He made the roster for the Desert Valley Mountain Lions in 2010 and, later that year, went on to play in the American Association for El Paso Diablos (later in 2010), the Winnipeg Goldeyes (2011 and again in 2014), Sioux Falls Pheasants (2012), and the Gary RailCats (2014).
