This study replicated Christiano’s inquiry on race and salaries in major league baseball in 1987. However, instead of merely dichotomizing the independent variable into black and white, the data were trichotomized into white, black, and Hispanic categories. Unstandardized regression coefficients (after disaggregating the observations by race / ethnicity, position, and free agency status) revealed several instances of salary inequities but no systematic patterning. The conclusion: The salaries of baseball players varying in race / ethnicity were not consistently different even while holding other theoretically relevant variables constant.

This study refined and extended Christiano’s recent inquiry on race and salaries in major league baseball. Instead of merely dichotomizing the independent variable into black and white, the data were trichotomized into white, black, and Hispanic categories; pitchers, because they were not studied, provided the focal point. A model of salary for pitchers was both specified and tested. Unstandardized regression coefficients (after disaggregating the units of analysis by race/ethnicity) revealed several instances of salary inequities but small ns precluded systematic testing. Hence, the verdict is still out as to whether or not the salaries of baseball pitchers varying in race/ethnicity are consistently different while holding other theoretically relevant variables constant.

A series of multiple regression analyses using the most recent publicly available data on the salaries of veteran hitters in major league baseball uncovers little evidence of economic discrimination by race. Comparisons of unstandardized regression coefficients for player variables, by race and position, reveal a number of instances of inequality. However, these inequalities do not occur consistently with respect to the same type of performance, nor do they always place blacks at a disadvantage. Furthermore, blacks who do not enjoy the market power granted to players by the advent of free agency are not uniformly victimized by discrimination in salaries. Instead, the newest evidence suggests that signs of salary discrimination that were found in data on hitters from the 1977 season are not manifest 10 years later.

PurposeSensorimotor variables have been shown to predict performance in professional baseball players. However, cardinal gaze speed in baseball players has received only limited attention. This study tested the hypothesis that the cardinal gaze speed in Major League Baseball (MLB) players would be faster than in amateur prospects and non-athletes. MethodSeventeen MLB athletes, 160 amateur prospects, and 128 non-athletes were tested using an eye-tracking test (i.e., the RightEye CGP test) designed to measure cardinal gaze speed. ResultsMLB players had significantly faster cardinal gaze speed than either amateur prospects or non-athletes. Moreover, there were significant differences in cardinal gaze speed across different directions. ConclusionsThis was the first study to examine the speed of gaze in the cardinal positions in an athletic context. The results highlight the significant difference in cardinal gaze speed between MLB players, amateur prospects, and non-athletes.

Background: Numerous studies have investigated injuries and treatments in the baseball athlete. The majority of these studies have focused on the throwing shoulder and elbow. However, more recent literature is reporting injuries to other regions in this cohort, including the knee, head, hip, and hamstring. Purpose/Hypothesis: The purpose of the current study was to determine the number and type of injuries in Major League Baseball (MLB) and Minor League Baseball (MiLB) players that do not occur during the actual game but are related to baseball participation. Our hypothesis was that there would be a substantial number of injuries that occurred in professional baseball players during non-game situations. Study Design: Descriptive epidemiological study. Methods: Deidentified, anonymous data were collected from the 2011 through 2016 seasons from the MLB Health and Injury Tracking System (HITS) medical record database. All injuries that were identified as a primary diagnosis and resulted in at least 1 day out of play from both MLB and MiLB were examined. Injuries were categorized as occurring during the game (“game” injuries) or not during the game. A “non-game” injury was defined as occurring at any time other than during the scheduled game from the first to last pitch. Results: There were 51,548 total injuries in MLB and MiLB players from 2011 to 2016, almost 40% of which were attributed to non–game-related injuries (n = 19,201; 37.2%). The remainder occurred during a game (n = 32,347; 62.8%). A significantly greater percentage of non-game injuries were season ending (10.8%) compared with the percentage of game-related season-ending injuries (8.4%) ( P < .0001). Pitchers had significantly more non–game-related injuries than game-related injuries ( P < .0001). Conclusion: A large number of injuries occur in professional baseball outside of actual games. MiLB players, specifically pitchers, are particularly at risk for these types of injuries. It is feasible that the overall injury rate in professional baseball players could be reduced by analyzing these injuries in more detail to develop prevention strategies.

Category: Ankle, Sports, Trauma Introduction/Purpose: The purpose of this study was to determine the injury characteristics of ankle and lower leg injuries in professional baseball players during the 2011-2016 seasons by utilizing the Major League Baseball (MLB) injury surveillance system. Methods: Our study is a descriptive epidemiological evaluation through a retrospective review from the MLB Health and Injury Tracking System (HITS) since its implementation in 2011. We included any professional baseball player (Major League and Minor League) who was identified as having an ankle or lower leg injury from January 1, 2011 through February 28th, 2017.Over the study period there were a total of 4,756 injuries of which 763 (16.0%) occurred in the Major League and 3,993 (84.0%) occurred in the Minor League. Results: The average number of days missed for all players was 27.8 days (+/-141.4 days) with a median of 3 days. From 2011 through 2016 it was estimated that there were 414,912 athlete exposures (AEs) in Major League Baseball and 1,796,607 AEs in the Minor Leagues. Of the 4,756 injuries recorded, 550 (11.6%) took place during the Major League regular season and 3,320 (69.8%) took place during the Minor League regular season. Major League injuries, however, were 1.7 times more likely to require surgery (p < .001). Additionally, rates of injury to the lower leg were stratified by position with infield players experiencing injuries at a 1.6 times greater rate than any other position (p < .001). Conclusion: In conclusion, the data from this study represents the only epidemiological study to focus primarily on lower leg injuries in professional baseball players utilizing an injury surveillance system developed by MLB.

Objectives: Superior labral anterior-posterior (SLAP) tears are a common source of inability to play among baseball players of all levels. SLAP repair is unpredictable and thus biceps tenodesis (BT) has been proposed as an alternative. Furthermore, tenodesis may be indicated for pain isolated to the biceps tendon. The incidence of BT among professional baseball players is unknown, as are the rates of return to play (RTP). The purpose of this study was to determine RTP rates after BT among professional baseball players. Methods: Major League Baseball (MLB) has maintained a prospective database containing all major and minor league baseball players who have undergone shoulder surgery since 2010. Using this database we determined the incidence, demographics, position, prior surgical history, concomitant procedures, RTP rates, time to RTP, and performance upon RTP for professional baseball players following BT. Minimum follow-up was 2 years. Results: Between 2010 and 2013, 17 professional baseball players underwent BT, of which 71% were pitchers, and 29% were in the major league. Forty-seven percent had a history of prior shoulder surgery and 47% underwent concomitant labral repair. Overall RTP after BT was 35%. RTP for isolated BT was 44% in 0.8±0.5 years while RTP for those who underwent both BT and labral repair was 25% (p=0.620). All players who RTP were able to return to at least ten games at their pre-operative level of play. Return to professional play was significantly more common among position players than pitchers (80% vs. 17%, p=0.028). RTP was less common among players with prior shoulder surgery, but this was not statistically significant (56% vs. 13%, p=0.131). For those players who did RTP, pre-operative and post-operative performance was unchanged. Conclusion: Professional baseball players who undergo biceps tenodesis have a 35% rate of return to their prior level of play. While pitchers have only a 16% rate of return to play, position players have an 80% rate of return to play. Furthermore, 100% of those who returned to baseball played at least 10 games at their pre-operative level with no significant change in performance statistics. Professional baseball players who choose to undergo biceps tenodesis should be counseled regarding the low rates or return to play. Pitchers in particular may have a poor prognosis following tenodesis. However, given the small sample size and concomitant procedures, further study is needed before definitive conclusions can be made.

Background: Hamstring strains are the most common injury for professional baseball players and can result in significant time on the disabled list. To date, no study has reported the current trends in hamstring strains in professional baseball. Hypothesis: Professional baseball players would have an increased incidence of hamstring strains from 2011 through 2016. Study Design: Descriptive epidemiology study. Methods: Injury data were prospectively collected from 2011 through 2016 for every Major League Baseball (MLB) and Minor League Baseball (MiLB) team and was recorded in the MLB Health and Injury Tracking System. Data collected for this study included date of injury, activity during injury, time lost, primary injury or reinjury status, and imaging findings as well as player demographic information related to level of play, age, and position for all hamstring injury events. Injury rates were reported as hamstring injuries per number of games. Results: From 2011 to 2016, there were 2633 hamstring strains in professional baseball players. The rate of hamstring strains increased in MLB from a low of 1 injury every 39 games in 2011 to a high of 1 injury every 30 games in 2016. In MiLB, there were 2192 hamstring strains, with 1 injury every 35 games in 2011 compared with 1 injury every 30 games in 2016. The majority of injuries occurred in the infielder positions (37.5%) and resulted from base running (>50%), most commonly from home to first base. The most common hamstring injury was a grade 2 injury to the distal biceps femoris. The mean time missed after a hamstring injury was 14.5 days. Grade 3 and grade 2 hamstring strains resulted in significantly more days missed compared with grade 1 injuries ( P = .005 and P = .002, respectively). The rate of recurrent hamstring injuries was 16.3% for MLB and 14.2% for MiLB. Recurrent hamstring injuries resulted in more time lost than primary injuries (mean, 16.4 vs 14.5 days, respectively; P = .02). A total of 42 injuries were treated with platelet-rich plasma, and 19 were treated with surgery. The number of injuries treated with platelet-rich plasma increased in successive years. Conclusion: The rate of hamstring strains in professional baseball players has increased over the past 6 years and has resulted in a significant loss of playing time. Study results indicated that these injuries are affected by injury characteristics, position played, running to first base, seasonal timing, and history of hamstring injuries.

Background: Isolated ulnar nerve decompression/transposition is an uncommon surgical procedure among professional baseball players. Purpose/Hypothesis: To determine performance and rate of return to sport (RTS) among professional baseball players after isolated ulnar nerve decompression/transposition, including those who required decompression/transposition after ulnar collateral ligament reconstruction (UCLR), and to compare outcomes between cases and matched controls. The authors hypothesized a high rate of RTS among professional baseball players undergoing isolated ulnar nerve decompression/transposition with no difference in RTS rate or performance between cases and controls as related to earned run average, WHIP ([walks + hits]/innings pitched), wins above replacement, and on base + slugging percentage. Study Design: Cohort study; Level of evidence, 3. Methods: Utilizing the injury database of Major League Baseball, we identified all professional baseball players who underwent isolated ulnar nerve decompression/transposition between 2010 and 2016. De-identified demographic and performance data (before and after surgery) for each player were recorded from Major League Baseball records. Performance metrics were then compared between cases and matched controls. Results: The study included 52 players; 83% were pitchers; and 14 underwent prior UCLR. Most surgical procedures (92%) were anterior subcutaneous transpositions. Overall, 62% of players were able to successfully RTS, and 56% returned to the same or higher level. There was no significant difference between cases and controls in the majority of pre- and postoperative performance metrics—specifically, earned run average, WHIP, wins above replacement, and on base + slugging percentage. When players who had UCLR before ulnar nerve decompression/transposition were compared with controls with a history of UCLR but no subsequent ulnar nerve decompression/transposition, the only performance difference of all the recorded metrics was that cases allowed more walks per 9 innings (4.4 vs 2.8, P = .011). Conclusion: Anterior subcutaneous transposition is the most common surgical procedure among professional baseball players to address ulnar neuropathy at the elbow. Players have a 62% rate of RTS, which is lower than expected for this nonreconstruction or repair procedure. For players who successfully RTS, performance metrics versus matched controls remained the same except for allowing significantly more walks per 9 innings. Postoperatively, pitchers with UCLR before ulnar nerve decompression/transposition who had a successful RTS performed the same as matched controls with prior UCLR without subsequent ulnar nerve decompression/transposition.

Revenue Product

Major League Baseball was granted an exemption to antitrust laws in 1922 by the Supreme Court. This exemption led to the creation of a monopsonistic labor market that prevented baseball players from fielding offers from other organizations once that player signed with any Major League Baseball team. Economic theory predicts that such a market would reduce a worker’s wage below a worker’s marginal revenue product. The question this study seeks to address is how much wage depression existed before the introduction of free agency in baseball in 1976. Specifically, we will examine the Hall-of-Fame career of Bob Gibson, a career that ended in 1975. Our examination will not only explore the standard approach economists have used to answer this question for more than forty years but also a simpler approach that gives a more realistic answer to the question.
