Gray is averaging exactly five innings per start this season (50 innings, 10 starts), and at five innings a start, six strikeouts requires better than a strikeout per inning. He has produced that twice in his last six outings; the other four landed at 4 or below. The model projects 5.35 against the 5.5 line and grades the under at 62 percent against a 58.3 percent break-even.

The Matchup Context
The Yankees whiff 8.73 times per game, which is why this line is 5.5 rather than 4.5, and that is priced in. The model's case is workload arithmetic: Gray's last six strikeout counts read 2, 2, 6, 9, 4, 7, and the big numbers came in his longest outings. In a hostile road park where traffic shortens starts, the five-inning version of Gray is the likelier one, and five innings rarely produces six punchouts.
The Probability Distribution
The model spreads Sonny Gray's outcomes across a Poisson-style curve calibrated to its 62 percent under probability (distribution parameter 4.98). Green bars cash the ticket; orange bars lose.
