Hamstring strain injuries (HSIs) are extremely prevalent injuries in the collegiate baseball setting. HSIs require plentiful rest and rehabilitation to regain the normal functions of the injured leg meaning athletes will not be able to participate in competition. Time loss from sport has negative effects on the injured athlete and their team. For these reasons, it is important that athletes receive the best possible treatment to get them back on the field as quickly and safely as possible. Eccentric strength training has been shown to be the most effective rehabilitation and injury prevention measure for HSIs. Eccentric training is often accompanied by many other treatment interventions such as soft tissue work, electric muscle stimulation, and many others. One treatment intervention that is relatively new in the clinical setting is trigger point dry needling (DN). DN has been shown to be effective at reducing pain and enhancing flexibility, but research as to whether or not it can speed the recovery of athletes with HSIs is lacking. There is also no research involving DN and baseball players. The purpose of this study is to explore the potential relationship between DN techniques and the return to play time in baseball players with acute grade I HSIs. This will be accomplished through the comparison of return to play time (DV) in a group of baseball players who receive dry needle interventions supplemented with their eccentric training protocol versus baseball players going through eccentric training alone (IV). It is hypothesized that the group of participants who receive DN will have significantly shorter return to play times
