Found this and thought it might make for an interesting addition to this thread. It's from Hard Ball Times LINK . I only put a little chunk of the article in here that has the similar chart. There's much more at the link. However, we need to look deeper. If Felix is throwing his fastball on 3-0 counts, and his breaking stuff on 0-2 counts, it?s only natural that hitters will be teeing off on the fastball. So let?s take a look at the data by ball/strike count: Pitches FB CB CH FB% CB% CH% Opp. OPS 0-0 60 24 17 59.41% 23.76% 16.83% 1.063 0-1 21 21 6 43.75% 43.75% 12.50% 0.889 0-2 17 13 3 51.52% 39.39% 9.09% 0.200 1-0 28 6 9 65.12% 13.95% 20.93% 0.880 1-1 10 9 6 40.00% 36.00% 24.00% 1.080 1-2 29 16 3 60.42% 33.33% 6.25% 0.353 2-0 13 0 3 81.25% 0.00% 18.75% 1.222 2-1 11 0 3 78.57% 0.00% 21.43% 1.000 2-2 10 17 3 33.33% 56.67% 10.00% 0.645 3-0 3 0 0 100.00% 0.00% 0.00% 2.000 3-1 7 0 0 100.00% 0.00% 0.00% 1.758 3-2 9 2 2 69.23% 15.38% 15.38% 1.155 Lots of information there?and yes, small sample size caveats heavily apply?but it all has the same general theme. On counts where you?d expect a hitter to be sitting fastball (1-0, 2-0, 2-1, 3-0, 3-1), Felix is complying, throwing significantly more fastballs when behind in the count than when he is ahead in the count. When he gets two strikes, you see an awful lot of curveballs as he goes for the punchout. However, if the hitter is able to work it into a fastball count, they almost always get one, and they?ve been punishing him for it. (cleaned it up a little -TC)
