The Uncommitted Spotlight Series continues as we have started the '24 CIF High School baseball season Prep Baseball California is now highlighting some of the top uncommitted class of '25 athletes. The players featured are pulled directly from our '25 Class Rankings. These JR year players are ones that college coaches and fans should be keeping their eyes on over the coming months.

We invite you to get to know them through the eyes of our Prep Baseball California staff of scouts and the data-backed numbers collected at our events with our partnered companies. TrackMan, Blast Motion, Swift Performance, and Visual Edge provide comparable data to project and evaluate players. All of these systems come together to give a clear picture at what colleges will get when a players steps onto their campus.

Today, we put the spotlight on a NorCal '25 OF Mason Dennis from Rio Americano High School. Dennis presents an athletic wiry build at 6' 170 lbs frame with the actions and speed that show a versatile defensive profile with an intriguing offensive potential. His 7.02 speed in the 60 with good run speed (19.9 MPH max run speed) give him an upside to potentially play CF, but will need to see an increase in his 80 MPH OF arm velocity to make the move to RF, but can be an above average defender in LF. Dennis shows quality swing metrics across the board with quickness in his bat path (72.1 MPH max bat speed) that comes from quick hands (23.1 MPH max) while showing present ability to generate torque in the turn of his swing (17.4 G's of Rotational Acceleration). His raw power shows more gap to gap doubles at its present upper ends by reaching 91.1 MPH on his max exit velocity and Dennis does a good job of consistently finding his barrel with authority at contact showing 87.1 MPH average exit velocity and a 88% sweet spot rate.  With good athletic ability, versatility to his defensive position profile, solid offensive ability and an intriguing frame that profiles to add strength as he matures Dennis is a name to know in the '25 class for college programs looking for outfielders with upside.
