The Relationship

Background: Injury rates among Major League Baseball pitchers have been increasing over the past several years. It is currently unknown whether pitching a complete game (CG) is a risk factor for spending time on the disabled list (DL). Purpose/Hypothesis: The purpose of this study was to determine the relationship between pitching a CG and time on the DL. We hypothesized that pitchers who threw a CG (1) would be at increased risk for spending time on the DL, which would be earlier in the season and for a longer period, than those who did not and (2) would be at further increased risk for spending time on the DL during subsequent seasons than matched controls. Study Design: Descriptive epidemiology study. Methods: Pitchers who threw a CG between 2010 and 2016 at the major league level and were placed on the DL during the same season were included. Timing and length of period on the DL were determined, as well as placement on the DL during subsequent seasons. Matched controls who did not throw a CG were assessed for time spent on the DL during that season and subsequent seasons. Results: Overall, 246 individual pitchers (501 pitcher-seasons) threw at least 1 CG between 2010 and 2016. Of the pitcher-seasons, 370 (73.9%) included a period on the DL, as compared with only 20% of controls. There were no differences in length of time on the DL ( P = .928) or days from season start to time on the DL ( P = .861) between pitchers who threw a CG and controls. Pitchers who threw a CG were significantly more likely than controls to spend subsequent seasons on the DL (1.9 ± 1.1 vs 0.5 ± 0.9, P < .001). Conclusion: Overall, 74% of pitchers who threw a CG spent time on the DL, as compared with 20% of controls. Pitchers who threw a CG during the study period spent more time in subsequent seasons on the DL than did matched controls who did not throw a CG.

The Relationship

The purpose of this study was to analyze the relationship between coaches’ professional playing experience and their professional coaching success. The sample (n = 134) included coaches who had the equivalent of three full seasons of head coaching experience in either Major League Baseball (MLB) (n = 46), the National Basketball Association (NBA) (n = 38) or the National Football League (NFL) (n = 50) as determined by the total number of games coached between the years 1997-2007. ANOVAs revealed no significant differences between coaches with more or less professional playing experience and professional coaching success as determined by professional winning percentage. Further, no significant relationship was found between professional playing experience and professional coaching success in MLB (r = -0.16), NBA (r = -0.05) or NFL (r = 0.00). It was concluded that professional playing experience was not a predictor of professional level coaching success. These findings support the notion that sources of knowledge other than playing experience may be necessary and useful in developing coaching expertise.

Background: Repetitive pitching produces significant stress on the elbow that may result in structural abnormalities discernable on magnetic resonance imaging (MRI) without causing symptoms. Purpose: To determine whether there exists an association between subclinical MRI findings in asymptomatic elbows of Major League Baseball (MLB) players and future placement on the disabled list (DL) or future operative procedure. Study Design: Cohort study; Level of evidence, 3. Methods: MRI scans of the elbows of professional-level baseball pitchers, taken during routine presigning imaging at a single organization from 2005 to 2017, were retrospectively reviewed. Publicly available databases were queried to exclude pitchers with an injury before the earliest session of elbow MRI. Three blinded reviewers reviewed all MRI scans independently to evaluate for the presence of chondral damage to the joint, loose bodies, ulnar collateral ligament (UCL) heterogeneity or tears, flexor pronator mass defects, and signs of posteromedial (PM) impingement. Binary imaging findings were related to future placement on the DL for elbow complaints and future elbow surgery. Results: A total of 41 pitchers had asymptomatic MRI findings with no prior DL placement. For players who eventually went on the DL, there were a statistically greater number of players with UCL heterogeneity ( P = .021), humeral-sided partial UCL tears ( P = .031), and PM impingement ( P = .004) on preinjury MRI compared with players who remained healthy. PM impingement was related to future elbow-related surgery ( P = .003). Pitchers with UCL heterogeneity were associated with reduced career strike zone percentage, innings pitched, and fastball percentage ( P < .05 for all). Conclusion: UCL heterogeneity, PM impingement, and humeral-sided partial tears were correlated with future DL placement for elbow-related reasons in MLB pitchers. Asymptomatic PM impingement may be a precursor to future surgery.

The Relationship

The relationship between age and the level of performance of major league baseball players was assessed through quasi-experimental designs. Whereas cross-sectional comparisons revealed no differences in batting and fielding statistics between younger and older players, longitudinal analysis showed significant decrements in batting performance as players aged from 30 to 35 years. A decline in performance with age was found even among elite players. Age decrements in achievement need to be studied not only in the context of molar measures such as batting statistics but also at a microanalytic level through reference to component skills. This paper outlines a methodology that can be used in assessing the nature and basis of age decrements in skilled athletic performance.
