Loose athleticism. 6'2", 185 frame has room to fill out another 10-15 pounds without compromising physicality. Fluid in motions, easy actions.

Modesto Nuts (High A, Rockies)
Competitive instinct, quiet confidence. Engaged throughout infield practice, gets annoyed when he doesn't execute perfectly. Takes grounders seriously during infield and between innings. Appears to get along with teammates.
55/borderline first-division player
Moderately wide base, loose hands, good starting rhythm. Progression into load can get methodical and stiff with rigid hand movement. Long coil action, back elbow drifts high at load. Has toned down progression but still retains excess length getting to his launch. Strong wrists and forearms, front shoulder clears efficiently. Can lose engagement with hips and become reliant on arms/hands for barrel delivery and bat speed. Generates excellent leverage and loft. Bat path is steep into the zone, can get uphill. Hunts fastballs early in counts, will expand against off-speed. Tracking ability improving but still raw. Smart hitter with a plan in the box, will take a walk. Strong plate coverage, can get compact to cover inner-third. Pull-heavy approach at present.
Raw is easy plus, should eventually get to most of it in games. Potential for half-grade jump to both raw and game with additional muscle. Stays reasonably balanced and within his mechanics when he turns to drive. Well-leveraged swing, bat path allows for easy back-spin and loft. Game power to RCF, has not demonstrated desire/ability to drive the ball oppo.
Fringe-average at present may ultimately play down to 40 with added bulk. 4.28 clock on a long finish. Not an overly-aggressive baserunner, takes conservative leads.
Engages early pre-pitch, balanced set-up. Moderate rock forward at delivery to maximize first-step. Above-average lateral quickness, good length. Decisive in his reads, plays spin and anticipates hops well. Athleticism plays. Controls his body, consistent with his footwork. Smooth action from field to transfer. Adept at charging the ball. Won't be the rangiest defender, but above-average quickness and good hands give him the tools for 55 defensive profile.
Raw velocity is above-average, plays up with footwork, quick release, and accuracy. Gets on top well, below-average tail on his ball. Demonstrated accuracy from multiple arm angles to first and second base. Outstanding body control transferring and releasing on the run.
McMahon is a solid across-the-board prospect without any glaring holes in his projection. He's among the younger regular position players in the California League, and while his swing and approach are both still works in progress he's held his own thanks to impressive athleticism and a broad foundation of skills. It'll require some seasoning, but there's an above-average hit/game power bat here, and with a frame capable of adding additional mass an outside chance for an actualized 55/60 hit/game power hitter at the hot corner. Coupled with above-average defensive projection he has the tools and talent to develop into a first-division Major Leaguer.
