| Summary: The glove is what gets Peck on a roster and the bat is what keeps him there — or doesn’t. A cerebral, instinctive defender with quick actions, fast hands and a blazing release that allows an above-average arm to play up, he handles shortstop, second base and third base with ease and reads difficult hops naturally. The range and defensive IQ give him genuine above-average value across the infield regardless of where the offensive profile lands. At the plate, the power is more real than the profile might suggest on the surface. Quick hands and a smooth inside-out swing generate hard contact to all fields, and the ability to elevate and drive mistakes has flashed more punch than the groundball tendencies typically associated with spray hitters. The launch angle improvements in 2025 drove a meaningful slugging uptick that reinforces the power being underrated. The carrying offensive concern is the vulnerability against quality velocity and spin — elevated whiff rates when behind in counts have been a consistent theme, and that hole will be tested relentlessly as competition improves. The utility bench profile is where the profile points, and it’s a legitimate one. The defensive versatility across the infield is a commodity, and if the power gains hold and the strikeout rate continues trending down, the offensive floor is functional enough to hold a roster spot for a long time. | |||||||||||
