There were some interesting articles by Cubs bloggers posted on Carlos Marmol yesterday. I thought I would share them with you guys. The first is from obstructed view about Marmol's rate of BABIP:
BABIP Regression | Articles
So that article addresses what is going on with Marmol. Increase in BABIP combined with poor control has resulted in more opponents getting on base, and when more opponents get on base you give up more runs, and when you give up more runs you blow more saves. This next article is the one that was really interesting because it might address why the BABIP has increased by nearly 30 points this year and 70 from 2009 (also a healthy increase of LD% from 13% to 19% to 20%).
The next article comes from Harry Pavlidis. Full article is here, but this chart here shows the velocity of every Marmol fastball and slider from 2007 to the present. The top range is the fastball velocity and the bottom is the slider velocity. Two important things should stand out, and that the fastball is getting slower and the slider is getting faster meaning less separation between pitches which is a bad (really bad for a two pitch pitcher).
Read the whole article because it has interesting data on the movement of his pitches which is also becoming similar. Which again goes back to the point I was making earlier about Marmol's recent struggles is more due to his pitches becoming less effective than people "figuring him out."
BABIP Regression | Articles
Prior to the Cubs signing Carlos Marmol to a 3-year extension this past offseason, there was a lot of talk about how Marmol was one of those guys who could have a very low BABIP. His BABIP as a reliever since 2007 had been .241, which is well below the average and even below the average for an extreme fly ball pitcher. It's well over .300 this season and since the beginning of 2010 his BABIP is .312. That's higher than we'd expect even for an average pitcher, but quite a bit higher for someone like Marmol.
The increased BABIP results in an increased batting average allowed and thanks to Marmol's poor control, he's allowed batters to have an OBP of .357, which is quite a bit worse than league average
