The Surprising Way Jet Lag Impacts Major League Baseball Games

The most striking effect of jet lag was on poor defensive performance, exemplified best by home runs allowed by pitchers. An increased tendency to give up the long ball was seen among eastward travelers (but not westward travelers), and in both home and away groups. This single stat was enough to explain most of the jet lag effects observed in this study, and it was considered strong enough to negate home field advantage (call it “jet lag disadvantage”). In terms of actual numbers, jet lag-induced home runs resulted in increases between 0.1 and 0.2 runs per game. It may not sound like much, but in a 162 game schedule in which teams score anywhere between 700 to 800 total runs, that can made a big difference. The increases in home runs per game (0.107 for home teams and 0.073 for away teams) accounted for the majority (87 percent and 72 percent) of the extra runs allowed. That’s quite revealing.
