Shi Davidi tells us that the Blue Jays have promoted their minor league hitting coordinator Guillermo Martinez to be their hitting coach, replacing Brook Jacoby.
Martinez was a hitting coach and infield coach back in 2012 and then was in the Cubs system as a minor league hitting coach for four seasons before coming back to the Jays this year.
Martinez has a website.
And the Jays have hired Carson Cistulli from FanGraphs to work in their scouting department. Carson wrote a farewell to FanGraphs here.
