60 games means the same team could win 20 or 40 games easily without it being too weird. We saw the Nationals go on a horrific start to the season and then win it all last year, and we've seen the Phillies get off to hot strats and then have late season collapses the last two years.
Add to that the funky schedules and the cloud of Covid-19 looming over every team and it means that luck will be a much larger factor than in normal years. We could lose two or three of our best players for a week due to a positive test and have them miss 10% of the season without having any real injury, or symptoms. Equally a player who goes on the 10 day list for a minor injury will miss at least 1/6th of the season. This is true for everyone and impossible to know who will be most negatively impacted so you have to ignore it when making predictions.
31 games is equivalent to 83.7, or 84 Wins in a regular 162, and even with the tough schedule you have to be hoping that this is a better team than that, I'm not sure we're quite a 90 win team but I think 90 wins is reasonable so I'd put this 60 win team at about 33-34 wins, which should be good enough for second in the division.
