01/13/2017 - Baseball Factory All-America Pre-Season Rookie Tournament
Tristen had a strong weekend behind the plate. As a catcher, Tristen works around the ball and controls balls in the dirt with his chest. He shows a quick exchange and gains momentum well on his throws to second base which allow them to remain accurate and on-line to the bag. At the plate, Tristen sets up in a square stance and takes a short stride to the ball. He is smooth getting into his load and comes through the zone with decent bat speed, leading to consistent contact and line drives. Tristen has tremendous upside and will continue to improve with experience.

Tristen is a R/R backstop who is a defensive specialist. Defensively, he sits in athletically and presents a low target. He is quick laterally and bodies up pitches in the dirt. Transfer/exchange is quick/clean with accurate throws down to 2B (pop times of 2.56). With the bat, Rosell has a balanced setup with rhythm in his hands. He whips the barrel on a level path and engages his lower 1/2 well, hitting line-drives. Overall abilities in his game will improve with work on the following.
1. Arm strength (long toss)
2. Gain ground toward 2B
1. Shorter/more direct swing path
3. Contact points
