From the Wings press release:

Mason spent the 2012 season as the pitching coach of the Cubs’ Single-A Daytona affiliate of the Florida State League. In 2011, the Kentucky native was the pitching coach for the Cubs’ Double-A Tennessee club of the Southern League.

Doherty primarily assisted Red Sox hitting coach Dave Magadan in 2012. He spent the previous nine seasons with the Kansas City T-Bones of the independent American Association, serving as their hitting coach from 2003-09 and manager from 2010-11.

Mason was the bullpen coach for the St. Louis Cardinals from 2000-2010. He's been a pitching coach in the minor leagues the last two seasons.

Doherty was an assistant for Red Sox hitting coach Dave Magadan in 2012. Before that, he spent a dozen years as a coach and manager for the Kansas City T-Bones (independent).

Yup, and Mason's been pitching coach at a couple of other organizations the last two years.

Yeah, not much to know about Doherty other than his independent league time in Kansas City after college. His role as an assistant to Dave Magadan is very vague too.
