Will the 2020 Houston Astros team win 100 games for the fourth year in a row ?

They're losing 34 wins in Cole and Miley but having Greinke will help fill the void created when Cole left. So they'll need at least one starting pitcher and bullpen depth, and that's going to cost money. 

Right now they have $155M tied up in 8 players and another 8 players ossibly headed toward arbitration so they will have to choose and spend wisely if they decide to go the free agent route this winter.

If they can add a quality starting pitcher 100 wins is a real possibility. If not, they'll still win 90-95 games, and the division.

Not likely.  I will say 90-95 wins.

Whether they cheated or not, they still have enough legit talent to pull it off. It'll be tougher since they won't be able to get away with the banging next season now that they got caught.

Now that their cheating ways have been exposed, they’ll be cellar dwellers again!!!!

Without knowing who will stay and who will leave, it's impossible to say, but if I had to say yes or no right now, I will say yes.

No they will not because they will lose to the Washington Nationals who are the greatest team in world history.

They probably will but it remains to be seen who will be on the team next year.
