2013 Stats: 2-3 record, 22.1 IP, 5.64 ERA, 6.43 FIP, 9.27 K/9, 8.06 BB/9
Both Carlos Marmol and the guy on the next slide have no doubt received their fair share of hate mail from Chicago fans over the past few years, but 2013 might be the worst year yet for each of them.
First, a little bit of context on how bad Carlos Marmol has been.
From 2009-2012, Marmol's BB/9 rate was 6.73. Not only was that the worst rate among the 327 pitchers with at least 180 innings pitched over that four-year span, but it is 25 percent worse than the next-closest guy—Andrew Miller at 5.37.
If we change our view to split season numbers over the last four years, there are 1,307 instances of a pitcher throwing at least 50 innings in a season. Marmol has four of the 24 worst seasons, including a tie for worst with a 7.91 BB/9 rate in 2009.
Jonathan Sanchez and Kyle Drabek are the only other pitchers to have multiple seasons in the "top" 50. Neither Sanchez nor Drabek is currently in the major leagues.
Despite all that, Marmol's BB/9 is currently higher than in any of the previous four seasons. He's on pace to break his own record in futility.
At this point, you're probably wondering how in the world someone that erratic can still be a major league pitcher. Well, his 12.88 K/9 ratio over the past four seasons leads all pitchers with at least 180 innings pitched.
And despite all the walks, wild pitches and hit batsmen, he has had a very respectable ERA thanks in part to incredibly low home run ratios.
That's all gone out the window this season. His K/9 ratio is the lowest it has been since his rookie year, and a career-worst 16 percent HR/FB ratio is contributing heavily to a near-worst 5.64 ERA.
