The Chicago Cubs' pair of 10-game winning streaks in April and early May have set the early-season benchmark at 10 games, yet the bunched probabilities across the 10-21 game ranges reflect broad uncertainty over which clubs can sustain longer runs. With the schedule still relatively light and multiple teams posting strong recent form, no single roster has pulled away, keeping the implied probabilities for 13-15, 10-12, 16-18, and 19-21 games nearly identical. Factors such as bullpen depth, starter consistency, and upcoming interleague matchups continue to shape trader views, while historical patterns show that mid-season surges often extend the eventual mark well beyond the current high-water mark.
