Cubs vs Harang - Three things to Watch

2

Harang is "just" a good pitcher. Which is pretty darn valuable considering he's fairly reliable starter. He's nothing superb, though. Here are three things about Harang's stuff that could factor into today's match-up.

Jon Hale puts HITf/x and PITCHf/x together to study pop-ups. For you kids watching at home and wanting to be a better pitcher, remember this: up and in with more back-spin

New Arm of the Week: Mat Latos - Beyond the Box Score

+

Here's another. I also split his slider up a few ways since he seemed to throw it a few different ways.

Mat Latos made an impressive debut, or two, this month.

Batted ball insanity -- The Hardball Times

2

Photogrammetry + HITf/x = Fun. Using Matt Thomas' data from Busch III, combined with HITf/x, I examine the outcomes and labels applied to a couple batted balls.

Cubs f/x: Cubs v Phillies: Rodrigo Lopez Preview

10

It actually took a moment to remember Lopez, and that he used to be considered a quality starter. And a lousy one, pretty much went back and forth. He's making his third start as a Phillie against the Cubs.

Zack Greinke and Rich Harden both throw hard, but they don't locate the heater the same.

Cubs f/x: Kevin Hart Refresher

Hard thrower with a good curveball. Hart's first start in the majors could be, well, interesting.

Using HITf/x to measure skill -- The Hardball Times

6

Peter Jensen bins batted balls by speed and direction (spray and launch angles, horizontal and vertical angles) to derive expected outcomes. I'm working on the same thing, but using a slightly different approach. I look forward to comparing my results to Peter's.

New Arms of the Week - Tim Wood and Ryan Sadowski
