Tellez reminds me a lot of David Ortiz athletically. Sew a super athletic upper body with good rotational mechanics onto a stiff, unathletic pair of legs, and you get Ortiz and Tellez. They may even have comparable raw power, the difference being Ortiz’ ability to utilize that power effectively with a better swing path for putting the ball in the air.
The ball jumps off Tellez’ bat, but he’s very choppy getting to contact, limiting his power mostly to pitches up in the zone, where his plane is forced to level out more. What may save him from being a slugger who doesn’t slug enough is his raw hitting ability: Tellez has shown better contact rates than you’d expect and, partially as a result, the potential for a plus hit tool. Also, though his speed is extremely limited, he’s a smart base-runner who won’t kill you with poor decisions when he gets on.
Though he’s not a sure thing with the bat yet, I could very easily see him in the 50+ group without having to squint. I felt more comfortable with him here until he can make some swing adjustments. His bat will get him some kind of opportunity either way.
