2020 - finished 26-34
Dates of note on this list: in 2021, July 30 marked the trade deadline. The line up was reduced to a shell at that point, but it marked Kyle Finnegan's second career save, and second consecutive after the Hand for Adams deal. Only Luis Garcia remains as a player from the line up, and he's been forced to 1B from the middle infield.
How good were starts of the Dusty-era regular season teams? Look at the two fastest to 48 wins by date teams at the top of the list. By game (match), 2005 still beats them, and 2012 matches 2016.
