Dynasty: Ace Reese. The FanRanked staff dynasty board has Reese ahead, Reese #191 and Mayo #196, but the expert consensus has Mayo ahead (#333 to #633). The community rates them even, FRV 53.1 and 54.3.
JD on Ace Reese (Aug 25, 2026): Ace Reese has had probably the most impressive debut from anyone in this class with a .439/.519/.683 slash line across 54 plate appearances in A ball for the Mariners with more walks than strikeouts. At 6'4", 220, his left-handed bat looks like a middle-of-the-order presence for many years to come for the Mariners. I can see him being one of the faster movers from his class in the minors and locking down first base for the Mariners in 2028. They're currently giving him some run at 3B but I'm not sure if he actually sticks there long term. One of my biggest buys in the FYPD.
JD on Coby Mayo (Jun 3, 2026): What, are you going to quit on Coby Mayo now? I still think that the talent is there. He just needs to stop putting so many uncompetitive balls in play. I'm only ranking this high because I think in two to three years he could end up being somewhat valuable but right now he is effectively useless. Consider him a stash.
