Off the top of my head, here&#x27;s a list of reasons that may tip the scale of an outcome in favor of the worse overall team in a baseball contest, whether luck or other factors. (the first two are by far the most important, and are in general order of how much variability each factors to a game):<p>- sequencing (3 walks, 3 strikeouts, and a home run in an inning can end with 1 or 4 runs depending on sequencing)<p>- ball-in-play luck (batters have little-to-no control over whether their line drive finds a glove for an out or a gap for a double)<p>- pitcher&#x2F;hitter matchups favoring one team or another<p>- other luck over a single game (2+ errors in a game, 3+ home runs in a game, etc) that are well above the average for any team, but any team will have many of these games over the course of a season<p>- umpire strike zone favoring one team&#x27;s pitchers<p>- umpire calls consistency<p>- park&#x2F;weather favoring one team&#x27;s players<p>If you need any explanation on any of these I&#x27;d be happy to provide it. I&#x27;ll add more if I think of them, but this should give you a pretty good idea of why the best teams in baseball usually end up with a less than 60% win record.
