Stirling is a 6-foot-2, 170-pound RHP out of the Ontario Nationals program who is eligible as a 2025 and 2026. The projectable right-hander showed good feel for his entire arsenal and lived in and around the zone throughout his bullpen. The fastball sat in the 79-82mph range and plays well down in the zone. Stirling also featured a downer breaking ball at 69-71mph and a changeup at 72-75mph. Looks to be more in the tank for Stirling as he continues to develop over the next year and joins the 2026 class.
