Background: There has been minimal research investigating injury and pitching performance differences between Major League Baseball (MLB) and other professional leagues. Purpose/Hypothesis: This 2-team comparison between MLB and Japan’s Nippon Professional Baseball (NPB) involved affiliated players over 5 years. We hypothesized that teams would differ in the injury incidence, mechanism of injury, pitch velocity, and pitch type usage. Study Design: Descriptive epidemiology study. Methods: Between 2015 and 2019, pitching data as well as injury statistics for the highest level and minor league affiliates of the Los Angeles Angels (MLB) and the Hiroshima Toyo Carp (NPB) were reviewed for significant differences in the injury prevalence, injury type, mechanism of injury, and days missed. In total, 3781 MLB and 371 NPB injuries were studied. Results: MLB-affiliated players were significantly younger, taller, and heavier ( P < .001) than were NPB-affiliated players. MLB-affiliated pitchers threw faster than did their NPB counterparts ( P = .026). MLB minor league pitchers threw more curveballs than did NPB minor league pitchers ( P = .004), and MLB minor league relief pitchers threw more sliders than did NPB minor league relief pitchers ( P = .02). The MLB team had a 3.7-fold higher incidence of injuries versus the NPB team (0.030 vs 0.008 injuries per player-game, respectively) as well as more repeat injuries, with fewer days missed per injury (15.8 ± 54.7 vs 36.2 ± 55.1 days, respectively; P < .001). The MLB team also had a higher percentage of injuries that were throwing related ( P < .001), were contact related ( P < .001), and occurred outside of competition ( P < .001) compared with the NPB team. Conclusion: This is the first empirical study examining injury trends and pitching characteristics between MLB and NPB athletes. MLB-affiliated pitchers threw faster and relied more on breaking pitches in comparison with NPB-affiliated pitchers. From injury data, MLB players were younger, taller, and heavier with a higher percentage of throwing-related injuries, contact injuries, and injuries sustained outside of competition. Overall, the MLB team indicated a 3.7-fold higher rate of reported injuries with fewer days missed per injury than did the NPB team. Competitive conditions are distinctly different between MLB and NPB, and thus, more extensive research collaborations in the future can identify best practices to advance health and performance for both leagues.

Objectives: In the setting of ulnar collateral ligament (UCL) injury, surgical reconstruction of the UCL is not always selected, as it leads to a prolonged recovery time and return to play rates between 67-95%. To date, there is limited data on outcomes following nonoperative treatment in this population. Orthobiologics, such as platelet-rich plasma (PRP), have recently been used as an adjunct therapy for standard nonoperative treatment including rest and physical therapy for UCL injuries. The objective of this study was to determine if the addition of PRP injections in professional baseball players with UCL injuries reduces recovery time, lowers the likelihood of surgery, and increases the return to play rate compared to traditional nonoperative treatment. Methods: The Health and Injury Tracking System (HITS) database was searched from 2011-2015 for Major and Minor league baseball players with Grade I, II or III UCL injuries. Standard demographic, injury, and return to play data was obtained for all players. MRI’s for 353 athletes were reviewed by a musculoskeletal radiologist and graded accordingly. Outcomes were compared between players who received PRP injections in addition to traditional nonoperative treatment (PRP group) and players who received traditional nonoperative treatment alone (No PRP group). Statistical analysis was performed using Student’s T-test and Chi-square for parametric data. Kaplan Meier’s analysis was used for estimating longevity of the treatment. Results: A total of 544 Major and Minor League Baseball players with UCL tears underwent an initial course of nonoperative treatment (active rest & rehabilitation) for their injury between 2011-2015. Of these, 133 underwent PRP injections plus rehab and 411 underwent rehab alone. There was a significantly higher proportion of Major League Baseball players in the PRP group compared to the No PRP group (25.6% vs 9.0%, P<0.001). There was no difference between the two cohorts in regard to the grade of UCL tear (Figure 1). The players in the PRP group had a significantly longer time before returning to a throwing program compared to the No PRP group (64 days vs 51 days, P<0.001). The mean time from injury date to PRP injection was 14.5 days, which may explain the difference in time to return to throwing. The return to play rate in a live game without surgery was significantly lower in the PRP group compared to the No PRP group (46% vs 57%, P=0.03). There was no difference in the proportion of athletes requiring UCL reconstruction (58% vs 51%) or the time to surgery (154 days vs 178 days) between the two groups. Kaplan Meier survivor analysis showed no difference between the PRP and No PRP groups with regard to longevity of the native UCL (Figure 2). Conclusion: Among Major and Minor League Baseball players who were treated nonoperatively for a UCL injury between 2011-2015, 24% underwent PRP injections prior to rehab. Compared to traditional nonoperative rehab alone program, players who received PRP injections experienced a significantly longer time before returning to throwing, which may be in part due to the delay between the injury date and PRP injection. PRP injections did not appear to have a significant effect on the likelihood of surgical intervention.

Purpose – The purpose of this paper is to understand why some sports show a positive economic impact and other sports do not, and to identify a common set of explanatory factors explaining the differences. Design/methodology/approach – This explanatory research reviews the economic impact literature to identify the underlying conditions that would theoretically allow any sport, large or small, to generate positive economic effects. Findings – Nine conditions are identified that, when present, could allow a community to experience a positive economic impact from a team or stadium. These are then used to explain the discrepancy in known empirical outcomes in major and minor league baseball (MiLB). It appears as if major league teams are more likely to violate the conditions than minor league teams. This research finds theoretical support for previous suggestions that smaller teams and events may be beneficial to local economies. In doing so, it also explains previous empirical results that found some MiLB classifications are associated with positive gains in per capita income. Practical implications – Stakeholders can use the nine conditions to understand expected economic impact of their relevant sports. This research provides a comprehensive guide to understanding when economic impact can be positive. Social implications – This research helps explain some of the existing controversy regarding economic impact analysis. Originality/value – It is the first research to help provide a pre-set of conditions that can help predict whether positive economic impact will occur for specific sports teams or stadium projects.

You are auditing the books of the Tallahassee BeanCounters (TBC), a minor league baseball team in Tallahassee, Florida. During your audit the team's owner, Franklin Kennedy, approaches you and offers an additional fee if you will quietly investigate the possibility of fraud within the firm. Mr. Kennedy reports that he received an anonymous tip and, based on that information, believes that someone within the firm could be perpetrating fraud. Your task is to use the information given here (the financial books and back-up documents) as a starting point for your investigation. From that starting point, use creativity and investigative skills to determine what other information you need. After obtaining requested information, use all the material you have gathered to determine whether fraud was committed. To completely solve a fraud, you must show the following: who committed the fraud, how it was committed, that it was intentional (not error), the economic impact of the fraud, and that it was your suspect who gained financially from the fraud.
