Thompson may have gone earlier in last June’s draft if it weren’t for his tendency to lose velocity after about pitch No. 80. Sitting 90-93 mph early and often dropping to 86-89 mph later suggests durability concerns, which leads to the idea that perhaps Thompson is an arm that more likely than not ends up in a relief role.

If the Mariners can reconcile this, the stuff will work in a starting role; sink on the fastball and a 73-77 mph curveball with two-plane break and depth. The changeup, like with pretty much every prep arm that comes to pro ball, needs work, but the arm action works well and Thompson is athletic and mentally tough.

The M’s love Thompson’s makeup, too, lending additional confidence in his chances to progress through the minors.
