Work With Us


For athletes looking to take their game to the next level, Delta Performance Softball's one-on-one pitching instruction is for you. Tailored specifically for the individualized needs of each pitcher, we give players a comprehensive understanding of their skill set and we’ll work our schedules around your busy lives.


$50/half hour


Group hitting lessons have proven to be valuable in many different aspects. The athlete will hit for an hour long with other athletes in similar age groups/skill sets to help push them to achieve their offensive goals. Group lessons will cover all aspects of hitting including mechanics, timing, and the mental side of the game. Groups are between 2-4 athletes




Delta Performance Softball clinics give athletes the choice of working with both Sammy and Shelby on pitching, defense, slapping and/or hitting for a reduced cost. Each weekly clinic date will meet for an hour on the same day of the four-week program, and the topics covered will progress throughout the length of the clinic. Stay tuned for future clinic dates.




After a successful 2019 and 2021 summer camp, Delta Performance Softball’s camps will return in 2023 to cover a wide variety of skills in great detail. Camps run a minimum of 4 hours and include instruction with water breaks, a Q&A, pictures, and autographs. Depending on numbers, additional professional instructors will be brought in to assist with camp.
