Treven Crowley RHP / SS / Hilmar, CA / 2020

Crowley, a 6-foot-1 165-pound right-hander, was one of the most impressive all-around athletes and talents at the trials. Strictly looking at him as a pitcher, he got up to 89 mph and sat in the 87-88 mph range for is pen session. He pitches from a high-3/4 slot and has a fast, loose arm with a longer arm action. His lift is short and unique in that regard. Crowley's curveball is a good one, a potential out-pitch at the collegiate level (possibly beyond), with 11/5 action and late power type break. Also showed a change-up that has a chance.

David Rodriguez 3B / RHP / Vacaville, CA / 2020

Rodriguez is a prospect on his merits as a 3rd baseman, but he also stood out as a pitcher. At 6-foot-0 170-pounds he seems to have more size than that. It's a good strong build and chance to be a physical body type. Pitches from a high-3/4 slot with a good arm that works pretty easily. He has a deep backside arm action and as he develops the ability to stay behind the ball better, his stuff could really spike. Rodriguez got up to 84 mph and sat around 82-83 mph, showing a heavy fastball and occasional good sink. Of his two secondary pitches, the change-up was better than the curveball. He finished the change-up well.

Matthew McMahon RHP / 1B / Cardinal Newman, CA / 2020

Long and lanky at 6-foot-2 150-pounds, McMahon is a fun one to watch from the perspective of projectability. His body will fill out more and still retain lankiness and the ability to be fluid with his delivery. He showed feel for all of his pitches and patience to let the ball move without forcing it. He finishes all three of his pitches (CB/CHG) well and that brings about some late life and action. His fastball was topping at 80 mph but given all of his other attributes and pitchability, if and when he does start touching the mid-80s, coaches will want to pay attention, because he's going to have a full repertoire and idea of how to get quality hitters out.

Tyler McCuistion SS / RHP / Rocklin , CA / 2021

Athletic player who has the delivery and aggressiveness of a shortstop on the mound. High-3/4 slot with a short and quick arm stroke. Gets to a good balance point and throws aggressively. There is some effort in the delivery but he's also working to be aggressive with his pitches. He does have some deception in his delivery. His fastball was up to 81 mph with some late life. The curveball was of the 12/6 variety and he showed feel of that pitch, which had late power break. Good feel of that pitch. Good extension and feel of the change-up which had good sink.

Victor Martinez RHP / 1B / Rodriguez, CA / 2020

Martinez is a 6-foot-2 185-pound two-way player with a strong athletic body type and good body control. On the mound he displayed the type of mound presence that exudes confidence and aggressiveness. Strong athletic delivery that he can repeat, with an on-line stride and good lower body stability. Could work to finish his follow through better. Fastball got up to 83 mph and steadily ranged in the 82-83 mph range. Secondary pitches also showed well, with the curveball and change-up both playing well off his fastball.
