5-foot-9, 160-pounds, Guillen was perhaps the most intriguing player to come out of the Tucson Open. The 2025 put together a great round of BP with line drives around the field and deep fly balls to the gaps. Guillen has a shoulder width stance and toe tap load, short hands to the ball and creates extension through. Right now Guillen looks to be a middle of the order type hitter with quality barrel awareness. With added size Guillen could be a top of the order type bat that will produce power to the gaps. At shortstop Guillen showed soft hands and good actions with the feet and a second best 85 mph across with an over the top arm action. We see Guillen staying up the middle of the field at the next level on the right side of the diamond. We look forward to watching Guillen go into his sophomore year at Salpointe Catholic as he is a high follow for the Arizona staff.
