If the astros somehow win 115 games this year the franchise will be over .500

their current record right now is 4,630 wins and 4697 losses. With the current 162, they could reach the milestone if they play out of their minds and win 115 games. If they win that many games their new franchise record would be 4,745 wins to 4,744 losses. This, however, is kind of a long shot but as long as they keep winning seasons they could reach it in the next few years.
