The Toronto Spread

For those who read the title and thought this post had something to do with food, I apologize, it does not. Instead, the spread I speak of refers to the pitch distribution in the Toronto Blue Jays starting rotation. Last month, when writing about Shaun Marcum’s hot start, some loyal readers commented that he was one of very few pitchers that threw five different pitches at least 10% of the time. Trying to verify this assertion I discovered that were only two other pitchers that fit this bill: Adam Eaton and Andy Sonnanstine.

It was recently revealed to me that Jesse Litsch joined the 5/~10% club. Catchy title, eh? I named it myself.

Now, not many starting pitchers throw even four different pitches at least 9-10% of the time and the Blue Jays have three of them: Dustin McGowan (4), Jesse Litsch (5), and Shaun Marcum (5). Group the three of them with the steady three-pitch mix of Roy Halladay and the fastball-curveball combo of A.J. Burnett and you have one extremely solid rotation.

Here are their pitch distributions, with velocity/frequency:

Roy Halladay: FA 92.7/45.9, CT 90.5/25.0, CB 78.2/23.6
A.J. Burnett: FA 94.1/66.2, CB 80.5/26.4
Dustin McGowan: FA 95.1/59.2, SL 87.6/19.3, CB 81.4/11.3, CH 86.7/10.1
Jesse Litsch: FA 88.8/17.7, SL 82.2/22.9, CT 85.0/37.5, CB 76.8/12.9, CH 80.0/9.0
Shaun Marcum: FA 86.8/39.0, SL 81.4/15.5, CT 84.5/14.0, CB 74.8/10.0, CH 80.9/21.5

Not only does this rotation mix their pitches effectively but their speeds as well; McGowan’s changeup is the same speed as Marcum’s fastball. Lastly, take a look at their stats:

Roy Halladay: 3.01 ERA, 1.01 WHIP, 5 CG, 12 BB, 72 K, 1.51 WPA
A.J. Burnett: 4.14 ERA, 1.37 WHIP, 33 BB, 71 K, 0.17 WPA
Dustin McGowan: 3.95 ERA, 1.42 WHIP, 28 BB, 55 K, 0.72 WPA
Jesse Litsch: 3.05 ERA, 1.13 WHIP, 9 BB, 33 K, 0.80 WPA
Shaun Marcum: 2.63 ERA, 0.94 WHIP, 22 BB, 67 K, 1.89 WPA

Their “worst” ERA is 4.14 and just one WHIP is over 1.40. Overall, the rotation has contributed 5.09 wins while being a steady and major factor in the success of the team. Perhaps their pitching coach has preached different spreads in order to, as a rotation, keep teams off kilter; whatever it is, though, it definitely seems to be working.
