Big, strong, well developed; impressive physical size; some softness to the body, may not age well; some concerns about so much weight on such a young player but has actually improved physical conditioning over the past year.
Dunedin Blue Jays (High A, Blue Jays)
50, Major league regular
Some movement in pre-pitch setup, low hands but gets into consistent hitting position; upright stance, uses height well; good swing path, direct to the ball, good plate coverage; above-average bat speed; patient approach; above-average bat control, especially for a tall player with some length to his swing; used whole field; strong understanding of the strike zone, approached at-bats with a plan.
Plus raw power, presently plays to above-average in games because of some natural length in swing due to long arms; could get to plus in games if he continues refinement of hit tool and swing mechanics; can leave the park to all fields; best when getting arms extended; creates backspin to all fields; ball jumps off his bat.
Very slow, will eventually be a base clogger; 4.76 to first base; will have no base running value; will not earn any additional hits with legs.
Not an asset defensively, but won't be a major liability either; hands are not soft but makes routine plays; limited range; won't help infielders often on bad throws.
Average arm, neither asset or liability.
Tellez has taken significant steps forward both in terms of his physical development and his baseball skills, turning himself into a potential everyday first baseman at the big league level. He uses his size well, and while it limits him defensively and on the bases to a profile that is completely reliant on his bat, it also gives that potential to provide enough value to get away with that profile.
Because of his size, he doesn't have to sell out for power, allowing his hit tool to play up. He shows strong bat control for a player of his size, and while there will always be some swing and miss because of the natural length in his swing, he maneuvers the barrel well within the strike zone and shows a propensity for using the whole field. He has plus raw power, and the progress of his hit tool will give that power a chance to reach its ceiling in the big leagues. Even if it falls just short, it should be enough to warrant regular playing time.
Tellez is a bat only prospect, which is a difficult profile, but with an above-average hit tool and the potential for plus power, he should have enough in his bat to still provide value in a major league lineup.
