Just what the Doctor ordered.

Andy at Baseball-Reference.com has an interesting blog entry about Doc’s perfect game. Roy Halladay was 0-3 in the game with two strikeouts, threw 115 pitches to 27 batters, and had a 98 Game Score.

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 $7/100000$ .
