Beckett in May

Josh Beckett of the Red Sox finished May with an impressive 1.00 ERA.  One reason for his excellent numbers came from Josh's performance against left-handed batters. They posted a .197/.282/.211 slash line against the right-hander, good for a .239 wOBA.  Notice that he used the whole strike zone against lefties:

David Ortiz Versus Lefties

Today Sean McAdam posted an interesting article on CSNNE.com regarding David Ortiz and his success versus LHPs. Here is an excerpt:

The three homers off lefties represent one more than Ortiz hit all of last season against lefthanded pitchers. He's done more damage against lefties in 55 at-bats this season than he did in 185 at-bats through the entire 2010 season.

"I guess everybody was questioning me hitting against lefties,'' said Ortiz. "I've said before, most of the time when you struggle against lefties, you're getting yourself out. You're chasing (pitches) out of the strike zone. That's pretty much what they try to make you do -- chase out of the strike zone. When you force them to stay in the strike zone, you've got to take advantage of it.''

It's a great read so we thought we would follow up with some graphics that help visualize David's success.

As advertised, Madson Avenue

Madison Avenue in New York is renowned as the advertising capital of the world. Occasionally, when we hear about a pitcher advertised as "having a great pitch," we take it with the same degree of hyperbole that we hear in an ad for a "great" product.

But today, I put the well-advertised change-up of the Phillies hurler, Ryan Madson, to the taste test, which in our case is our heat map.

The Taste Test

Let's start by looking at his fastball because the efficacy of a change-up is measured off the fastball.

Ryan Madson Fastball - In play averageYou can see as you look at the map, that of the 224 fastballs he has thrown, 39 have been put in play, resulting in 15 hits, producing an in play average of .385.

Let's see the change-up, Ryan.

Congratulations, Ryan you have passed the BaseballAnalytics.org taste test. Your change-up is as good as advertised.
