Open stance, very slight hand drift; longer bat path, plus bat speed; front foot lands open, generates torque; varies load transfer in anticipation of pitch, plants early when expecting offspeed; generates solid to hard contact with high frequency, high-BABIP hitter, works the middle and opposite fields; aggressive hitter, walks infrequently though not impatient; lots of swing-and-miss
Power the opposite way, tendency to pull in BP; strength of contact, directional approach will generate extra bases; flatter plane, lower-trajectory elevation, line drives carry with strength to clear fences; swing-and-miss frequency limits utility; more raw in the tank but home-run power plays down due to swing plane
4.21 home-to-first; full-speed effort on bases; position will limit future ceiling; not a stolen base threat, but will put pressure on defense
Sets quiet target, solid receiver, maintains firm hold; athletic behind the plate, will stab at pitches in dirt, to extremities; handles balls in play, plays at plate
1.89 pop; arm strength to impact running game; keeps throws around the bag, ball will sail, misses tend to be high
A Colombian international signee acquired from Texas in the Cole Hamels trade, Alfaro is a five-tool catching prospect with plus-plus arm strength. The hit tool shows average potential despite an aggressive, swing-heavy approach with a high propensity for swing-and-miss. He offsets those vulnerabilities with the ability to make hard contact, use the middle and opposite side of the field, and scratch out infield hits with his speed. Above-average raw strength and the ability to create hard contact should result in average power output, while his tendency to produce lower-trajectory hits could result in more doubles than home runs. The strength is there to leave the yard, however. He's a max-effort runner up the line and will show present plus speed, though the demands of the position are likely to diminish that.
Alfaro is a solid receiver behind the plate, though he'll get too comfortable at times and stab at balls rather than use his athleticism. Plus-plus arm strength helps to combat the running game. Has the offensive tool set to be more than just a catch and throw receiver, with the overall ability to develop into an above-average catcher.
