What a weird team.
Combined record, April 1 -> 15, September 1 -> 28: 9 wins, 30 losses, .231 winning percentage (Winning percentage, if extrapolated over a full season, would be the worst in MLB since 1899, and the third worst ever)
Combined record, April 16 - August 30: 81-42 (.658 winning percentage, on pace for 107 wins if extrapolated over a full season)
