Good, because Ray is outpitching Matz by leaps and bounds, Matz is just having one super lucky month with stranding runners and HR suppression - both really far out of line with his career norms. His fielding independent numbers are pretty unimpressive. Ray is an unlucky May from being the clear Cy Young frontrunner in the AL.
that's not to say I would be averse to re-signing Matz either, he's a solid #4/5, but he's not close to Ray's talent.
