Prep Baseball Report

Uncommitted Spotlight: '21 Jacob Kieffer


Brett Harrison
Nevada Scouting Director

Jacob Kieffer has progressed into one of the top arms in the Diamondback's program with a fastball that has continued to make velocity jumps over the past few months. Earlier this year at the Desert Oasis Scout Day, he topped out at 85 mph with seemingly more in the tank which proved true in the high school preseason tournament his fastball jumped up to 88 mph while sitting 84-86 mph. Then, during a recent bullpen he made another velocity jump, this time he climbed the ladder four more miles per hour up to 92 mph, according to the Pocket Radar on hand used by trusted PBR associates. The Future Games attendee compliments his recent velocity jumps with a pair of secondary pitches that he as continued to gain feel and command for in recent months. Kieffer is trending in the right direction with potential to be the next power arm to come out of Nevada and he will have his opportunity to showcase his progression at the Upperclass Top Prospect Games this summer.

2024-2025 Rising Stars Showcase

The PBR Nevada Rising Stars Showcase is coming Wednesday, June 24th to Desert Oasis High School. The event is open to Class of 2024 & 2025 Prospects. 

This event will have four main functions. For most participants, this will be their first showcase event - an initial step toward achieving a player’s baseball goals. Part of this event is educational. There will be a lecture about what scouts look for, how to comport themselves, what to expect in the recruiting process, and the overall landscape of playing at the next level. The second function of this event will be for players to create baseline numbers for themselves to improve. The third reason for this event is for PBR to have an in-depth look at the best young players and the future of the state.  The fourth function of the event is to identify players to represent Nevada at the PBR Junior Future Games held at LakePoint in Cartersville, GA.

PBR Junior Future Games Selection Process
