Yes, it appears the Seattle Mariners are not confining their youth movement to just the 40-man roster. Amongst the many changes to the coaching staff are new pitching, bullpen, bench, asst. hitting, and 3rd base coaches as well as a new Major League Field Coordinator.
And as you may have figured out by now, the Mariners didn’t go out and hire retreads from around the league. No, they truly have embraced a youth movement on their coaching staff. The new assistant hitting coach, Jarret DeHart, is just 25-years-old.
DeHart, who graduated from Tulane in 2017, went undrafted out of college and never appeared in a professional baseball game.
