Compared to Dallas Braden, Doc was much, much more likely to achieve this. Halladay’s opposing OBP is a miniscule $.297$ career, $.258$ this year, with his complementary probabilities of getting a batter out at $.703$ and $.742$. Using his career numbers, his probability of getting 27 consecutive batters out would be $.703^{27}$, or $.0000738$, which is approximately $7/100000$.
