I'm not buying into Moreno just yet. His offensive numbers are looking a bit like a mirage, as he's rocking a .398 BABIP at the moment without peripherals to back it up. His ground ball rate is nearly 60%, so it appears as though his impressive at a glance batting average is largely empty and largely dependent on ground balls finding holes. He has displayed minimal power and rarely walks, so the xWOBA is all of .298 vs actual of .326 so he may eventually see a correction in his results.
According to Statcast he's below average both in framing and blocking, so the bulk of his defensive value is from throwing runners out on the bases. Eventually teams will stop running on him so this will limit the defensive impact he's able to make by eliminating baserunners, and that will leave most of his value coming from singles at the plate.
