Pitch Framing - Is it Real?

Dan Turkenkopf — Sat, 05 Apr 2008 17:21:00 +0000

My latest post at Beyond the Box Score looks into whether certain catchers do better than others in convincing the umpire to call close pitches strikes and how many runs might be saved by turning balls into strikes. The results shocked me, and even cause me to question the outcome. Check it out and let me know what I did wrong.

Historical Catcher Block Percentage

Dan Turkenkopf — Thu, 20 Mar 2008 12:02:01 +0000

Ok, so not so much historical, but at least I can share 2005 and 2006. Joe Arthur clued me into the fact that the GameDay information was still available starting from 2005, so I dutifully went and grabbed the data, so now we have three years to look at.

UPDATE: MGL let me know about what turned out to be a rounding error that was pushing the numbers off a bit. I’ve updated the charts to fix the issue, but things might look a little different than you remember.

For those of you who haven’t been following this series, I’m using the GameDay data to measure how each catcher performed in blocking pitches by looking at their misses (wild pitches + passed balls) and their opportunities (balls in the dirt with runners on base).

Before we get to the results, a couple words of warning. There’s definitely something up with the scoring of balls in the dirt. Each year had widely varying counts for opportunities, as you can see below. If we assume that these scoring differences affected every catcher equally, then we’re ok if compare the runs saved columns since those are based on average numbers. I think this might be a reasonable assumption because the opportunities look to be somewhat depressed for all the catchers in 2006.

Year	Opportunities	Avg. Block %
2005	9271	.84
2006	7375	.77
2007	11523	.86

Opportunities and Block Percentage By Season

Also, I’m still wary of the effect of pitching staffs and of course random variation. One of the next steps is to try a With or Without You (WOWY) analysis to see if I can tease out the impact of the pitchers.

Enough of the warnings, let’s look at the results. I’ll go year by year, including 2007 for those who don’t want to look back at other posts, and then look at the leaders and trailers over the three seasons (by summing runs per season). Remember, I’m calculating an average block percentage for each season individually. I’m still limiting this to those catchers with more than 100 opportunities and assuming a run value of .27 runs per miss. I’ve changed the sort order to sort by actual runs saved rather than runs per 120, since I think the actual value is more interesting.

Catchers With More than 100 Opportunities in 2005
One big surprise in 2005: Jason Varitek, who the top catcher in 2007, is near the bottom here. He had 44 misses this season, while never having more than 24 in the other two seasons. I thought maybe he had been catching Tim Wakefield more in 2005 than in the other seasons. Turns out that Wake wasn’t the biggest cause of Varitek’s misfortune. Matt Clement actually led to 13 misses for Varitek that season, by far his highest number. This seems to be somewhat of a trend for Clement. Just looking at his WP numbers over the previous seasons he often has at least 10 wild pitches (and 23! in 2000), which puts him near the league leaders. Obviously Clement missed the large majority of 2006 and 2007, reducing Varitek’s misses. This quick look definitely highlights the need for a WOWY study.

Other than that, nothing too surprising. Mike Matheny, long considered a top defensive catcher, is number one. Pudge and Pierzynski are near the bottom. I’m happy to see the range of runs is roughly 12-15, right where it was for 2007.

Catchers With More than 100 Opportunities in 2006
Looking at this list makes me question even more the validity of the raw data from 2006. The range from top to bottom is still the same 12-15 runs, but the relative ranking is very different from 2005 and 2007. Of course that could just imply there’s a whole lot of random variation built into this measure, but I think there’s some systematic scoring issue that’s changing things.

Catchers With More than 100 Opportunities in 2007
I’ll present 2007 without much comment except to say that I feel more confident in the raw data than in either 2005 or 2006 because of the improvements to the GameDay system. Of course most of the improvements were technological and the scoring decision that leads to a measured opportunity is in the hands of the human stringer.

Leaders and Trailers

As a close, I’ll leave you with the top and bottom three in actual runs saved over the last three seasons.. I’ll admit I eyeballed this a little, so I may have missed someone. Also note that there were a bunch of catchers who might have made these lists but didn’t receive enough opportunities in all three seasons.

The Best:

Brad Ausmus	13.61
Yadier Molina	13.3
Jason Kendall	10.98

The Worst:

Ivan Rodriguez	-11.72
A.J. Pierzynski	-10.99
Jorge Posada	-7.93

How Valuable is Blocking Pitches?

Dan Turkenkopf — Sun, 16 Mar 2008 16:05:02 +0000

Now that we’ve looked at a raw ranking of how catchers performed blocking pitches in 2007 (subject to concerns about pitching staff, scoring and sample size), let’s try and turn that into runs.

Using Tango’s run expectancy chart (from 99-02, so it’s likely a little off based on the lower run environment now), a catcher miss (wild pitch or passed ball) was worth about .27 runs in 2007. Using that run value, and calculating blocks above/below average for each catcher, we can determine how many runs were saved by each catcher. The average block percentage across the entire league was 86%.

Now to put players on the same scale - which might be a little unrealistic based on the possible outside influences mentioned above. There were .27 opportunities per inning in 2007. Many people use runs per 150 games as a baseline for comparison, but since we’re talking catchers here, I think runs per 120 games probably better represents a full season. So that means a full season of opportunities should be 292 opportunities. This might be a little high since there were only 12 teams that had catchers with more than 120 games last season, so I’m willing to tweak if people think it’s necessary.

We’ll sort this table according to runs saved per 120 games, limiting still to those with over 100 opportunities.

Dave Ross	837.33	35	148	0.76	-14.28	-3.86	-7.88
Ivan Rodriguez	1052.67	58	214	0.73	-28.04	-7.57	-10.25

Mike Redmond retakes the top spot from Jason Varitek once we scale to the same number of opportunities, while Pudge looks worse again because of his low number of opportunities. However, he played almost as many innings as Varitek, but had almost 70 fewer opportunities. I don’t know if that’s an effect of scoring, pitching staff or simple variation, but it makes me wonder if, as rlc from BBTF suggested (comment 6), Pudge isn’t calling as many low breaking pitches as other catches would.

Anyway it looks like the range in value from blocking pitches is somewhere in the order of 12 to 17 runs (at least in 2007), which actually is higher than I would have imagined going in.

A tale of two catchers

Dan Turkenkopf — Sat, 15 Mar 2008 16:24:00 +0000

At least a couple of people have asked for some more detail about Doug Mirabelli, Tim Wakefield and blocking pitches. To no one’s surprise I’m sure, Mirabelli looks a lot better when you isolate out Wakefield. Basically he’s a completely different catcher.

Take all this with a grain of salt because the sample sizes are so small, but here’s how Mirabelli breaks down by pitcher:

Wakefield: 27 opportunities, 16 misses, 41% block percentage
Romero: 10 opportunities, 0 misses, 100% block percentage
Snyder: 6 opportunities, 2 misses, 66% block percentage
Matsuzaka: 4 opportunities, 0 misses, 100% block percentage
Pineiro: 4 opportunities, 2 misses, 50% block percentage
Lopez: 3 opportunities, 1 miss, 66% block percentage
Hansack: 2 opportunities, 0 misses, 100% block percentage
Papelbon: 2 opportunities, 0 misses, 100% block percentage
Okajima: 2 opportunities, 0 misses, 100% block percentage
Timlin: 1 opportunity, 0 misses, 100% block percentage
Delcarmen:1 opportunity, 0 misses, 100% block percentage
Tavarez: 1 opportunity, 0 misses, 100% block percentage
Donnelly: 1 opportunity, 1 miss, 0% block percentage

Total non-Wakefield pitchers: 37 opportunities, 6 misses, 84% block percentage

Catcher Block Percentage - Followup

Over on The Book Blog, Mike Fast raised the fact that I had left out the category of “Swinging Strike (Blocked)” when calculating the block opportunities.

Obviously including those pitches will change things somewhat, so without further adieu, here are the new numbers:

Catcher	Innings	Misses	Opportunities	Block %
Mike Redmond	482.67	7	135	0.95
Brad Ausmus	906.67	17	256	0.93

Jason LaRue	474.33	24	134	0.82
Miguel Montero	510.67	22	122	0.82
Miguel Olivo	990.33	65	321	0.8
Javier Valentin	471.67	22	108	0.8

Jorge Posada	1111.33	61	293	0.79
A.J. Pierzynski	1058	44	192	0.77
Dave Ross	837.33	35	148	0.76
Ivan Rodriguez	1052.67	58	214	0.73

It doesn’t appear to alter things too badly. Just shifts some positions around slightly and makes Pudge look a little better (but still worst in the league).

Other concerns that have been raised are the effects of the pitching staffs and the PITCHf/x scorekeepers. Unfortunately, I don’t really have a way to control for that at this point, so just keep those considerations in mind when using this information.

Catcher Block Percentage

Dan Turkenkopf — Sat, 15 Mar 2008 01:24:45 +0000

One of the things I’m interested in with the PITCHf/x data is seeing if we can better quantify a catcher’s impact on the game. The easiest thing to look at is how the individual catchers deal with balls in the dirt.

I looked at all the pitches classified by the Gameday scorers as “Ball In Dirt” with a least one runner on base - a total of 9907 for the 2007 season, spread across 96 different catchers. I considered these pitches to be the catcher’s opportunities to block a ball in the dirt. Brian Schneider led the way with 332 opportunities, with Jason Kendall and Gerald Laird the other catchers over 300 opportunities.

I then counted up all wild pitches and passed balls that occurred with the catcher behind the plate - let’s call them misses. Miguel Olivo had the most with 65, and Mike Redmond had the fewest with at least 100 opportunities at 7. Then I simply divided the blocks (opportunities - misses) by the opportunities to get a block percentage.

UPDATE: Mike Fast pointed out that I had missed the category of “Swinging Strike (Blocked)” when determining opportunities. I’ve rerun the numbers here.

UPDATE #2: I’ve added blocks above average and runs saved here.

Here’s the list for all catchers with over 100 opportunities in 2007:

Catcher	Misses	Opportunities	Block %
Mike Redmond	7	111	0.94
Jason Varitek	19	236	0.92
Brad Ausmus	17	210	0.92
Gary Bennett	10	121	0.92
Yadier Molina	27	259	0.9
Gregg Zaun	22	220	0.9
Brian Schneider	40	332	0.88
Gerald Laird	38	304	0.88
Chris Iannetta	12	100	0.88
Ramon Hernandez	32	255	0.87
Yorvit Torrealba	22	171	0.87
Russell Martin	40	280	0.86
Carlos Ruiz	25	184	0.86
Mike Napoli	23	166	0.86
Damian Miller	19	140	0.86
Jason Kendall	48	317	0.85
Ronny Paulino	35	233	0.85
Dioner Navarro	34	228	0.85
John Buck	32	217	0.85
Jeff Mathis	27	180	0.85
Kurt Suzuki	25	167	0.85
Josh Bard	24	161	0.85
Jarod Saltalamacchia	16	107	0.85
Brian McCann	34	219	0.84
Paul LoDuca	24	146	0.84
Johnny Estrada	37	221	0.83
Victor Martinez	29	173	0.83
Michael Barrett	25	148	0.83
Paul Bako	23	135	0.83
Matt Treanor	17	101	0.83
Chris Snyder	34	193	0.82
Mike Rabelo	20	113	0.82
Benji Molina	50	257	0.81
Kenji Johjima	40	215	0.81
Jason LaRue	24	129	0.81
Miguel Montero	22	113	0.81
Miguel Olivo	65	277	0.77
Jorge Posada	61	268	0.77
Joe Mauer	30	121	0.75
A.J. Pierzynski	44	160	0.73
Dave Ross	35	126	0.72
Ivan Rodriguez	58	184	0.68

Perhaps the most surprising placement on this ranking is Ivan Rodriguez in last. However, anecdotally he wasn’t very good defensively last year, and he’s always been better known for his arm than for his blocking ability. Joe Mauer is way down on the list, but it’s probably pretty tough for a tall catcher to get down to block the balls. Varitek ranks highly by this measure, which means he’s pretty good at blocking pitches that aren’t knuckleballs. Mirabelli, on the other hand, only blocked 64% of his opportunities - for which he can blame Mr. Wakefield.
