Crooked Innings

Here's a list of each starting pitcher and the number of times they've allowed multiple earned runs in one inning, and the percentage indicates the percent of earned runs allowed that have come via multi-run innings:
All Stats through May 13

David Price: 5 10 runs 66% of his earned runs h
Mitch Talbot: 5(two 4-run innings) 14 runs
Carlos Hernandez: 4(three 3-run innings and one 4-run inning)
James Houser: 2(one 4-run inning)
Wade Davis: 4(two 3-run innings)

MRI = Number of multiple run innings
ER = Total number of earned runs in those innings
%IP = Percent of innings pitched that have been multi-run innings
%ER = Percent of earned runs allowed that have come in multi-run innings

Player             MRI   ER   %IP    %ER 
Carlos Hernandez 4 13 13.8% 86.7%
Mitch Talbot 5 14 13.4% 82.4%
Wade Davis 4 10 11.8% 71.4%
David Price 5 10 17.1% 66.0%
James Houser 2 6 10.9% 60.0%

Aneury Rodriguez 7 18 21.9% 85.7%
Ryan Morse 4 10 15.0% 76.9%
Heath Rollins 4 11 10.1% 68.8%
Jeremy Hellickson 2 4 6.7% 57.1%
Jason Cromer 3 6 15.5% 54.5% *AA numbers only*

Jesse Darcy 7 17 23.9% 81.0%
Darin Downs 3 9 8.1% 75.0%
David Newmann 3 12 9.9% 66.7%
Jeremy Hall 4 9 14.1% 64.3%
Alex Cobb 2 5 5.9% 50.0%

Matt Moore 3 7 11.9% 77.8%
Shane Dyer 4 10 13.1% 66.7%
Frank De Los Santos 2 4 6.8% 44.4%
Michael Jarman 2 4 6.3% 44.4%
Neil Schenk 1 2 13.7% 100% *Stats as a starter only*
Chris Andujar 1 2 7.0% 50.0% *Stats as a starter only*
So, Alex Cobb and Jeremy Hellickson have done a great job at limiting the big inning, while the news isn't as good for Aneury Rodriguez and Jesse Darcy. David Price is something of an interesting case: He's allowed a high number of multiple-run innings, but he hasn't allowed more than two earned runs in a single inning. I don't have data for past years, but the big inning has always seemed like a problem for Mitch Talbot. I'll try to do some more work to see if this stat tends to regress to some sort of mean at all, or if numbers for each player tend to stay steady from year to year.

For what it's worth, the average %IP was 12.2 and the average %ER was 68.1, but I have a feeling Bowling Green and some small samples are throwing those off.
