Grip Strgth (LH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
‘25 C Isaac Pfeifer (Tualatin/Arizona State commit) lands in the #1 spot in our latest update. The physical backstop is a blue collar player who commands the game from behind the plate but also has the athleticism and baseball acumen to handle additional spots on the diamond. The arm strength plays well on the mound and it wouldn’t be a shock to see him impact the game as a 2-way prospect as he continues to develop. In the end, the hit tool stands out the most and it’s something we highly value in our evaluations. His natural ability to not only hit, but to hit for consistent power in game has ascended him to the #1 spot at the end of the summer.
Pfeifer’s maturity level extends far beyond his status as a young freshman, and already presents himself as capable of leading a pitching staff at the varsity level. The 5-foot-11, 180-pound backstop is built with some compact, natural strength and gets to it while hitting from the right side. Working slightly uphill through the zone, Pfeifer exhibits fast hands with some present gap-to-gap strength including upwards of 93 mph exit velocities. Defensively, accurate 76 mph throws with pop times of 2.04-2.09 stand out now, and should continue to get better. Overall, a quality first look at the young catcher who also showcases some arm talent on the mound where he already runs a fastball up to 85 mph.
