“The offense of jet-lagged home teams is much more affected than that of jet-lagged away teams. Surprisingly, in terms of offensive performance, jet lag from eastward travel had significant negative effects on home teams (after returning from a road trip) and much less of an effect on away teams.”

“Negative effects on offense are related to base running. The negative effects on the home team’s offense were related to base running, such as stolen bases, number of doubles and triples, and hitting into more double plays.”

“Both home and away teams suffer on defense, specifically by giving up more home runs. With defensive performance, strong effects of eastward jet lag were found for both home and away teams, primarily with jet-lagged pitchers allowing more home runs … Besides home runs allowed, few other effects were seen on pitching or defense.”

“There is a difference between traveling east and traveling west. Most significant jet-lag effects were generally stronger for eastward than westward travel.”
