Baseball Managers by Position Played

Mike Matheny, a former catcher, was just named manager of the St. Louis Cardinals. This got me thinking, knowing that Bruce Bochy and Joe Girardi were both former catchers, what’s the distribution of former positions of MLB managers.

It turns out catchers are by far the most popular former position for a manager, with ten of the twenty eight managers being former catchers. I was surprised there are only two pitchers.

Position Count %
C 10 35.7%
OF 6 21.4%
SS 4 14.3%
1B 3 10.7%
3B 2 7.1%
P 2 7.1%
2B 1 3.6%

Note: Positions based on play in Major or Minor league, several managers did not make it to the majors.

Current Managers in MLB as of Nov 17, 2011, 28, due to two empty positions at this time.

Data from Baseball Reference and Wikipedia

Baseball Wins vs. Attendance, which fans are loyal? fair weather?

I discovered the Baseball-Databank, a database of wonderful baseball stats that you can download. So now my math+data geek and baseball geek can merge until an uber dork. So don’t be surprised over the next several weeks as the baseball season is about to get underway and hope is in the air, to see plenty of stats about our national pastime.

First up, in today’s post I plotted a Wins vs. Attendance correlation for each team. This allows us to answer a few interesting questions: do wins contribute to attendance? who has the most fair weather fans? most loyal? Does a new ballpark have a bigger impact on attendance than wins?

How to read the graphs

The x-axis is wins and the y-axis is attendance. So the top-right corner is a high attendance and a high number of wins. The bottom left low attendance and low number of wins.

A loyal team plot would look like high horizontal line on the graph regardless of number of wins attendance stays high. A fair weather team would have a diagonal line, as wins increase, so does attendance. A disloyal fan base would have a low plot regardless of the number of wins.

What stories does the data tell

A couple of interesting things I gleamed out of the data:

  • The San Francisco Giants fan base was a pretty fair weather bunch until the new stadium in 2000 and then became one of the most loyal.

  • It appears the Minnesota Twins are the most fair weather fans, which seems appropriate for the Minnesota weather. The plot for the Twins is almost a perfect diagonal line, high correlation between wins and attendance.

  • The Baltimore Orioles graph looks to me as the most optimistic fans, there is a extremely step diagonal line, it is almost like they are saying, please just give us a few wins and we are there.

  • A few plots that are confusing to me; the Texas Rangers, Seattle Mariners and Colorado Rockies both have a surprisingly consistent number of wins, but attendance varies greatly.

  • As far as most loyal, tough to call but it might be the Atlanta Braves, it looks like they have a good base of attendance at 2.5m. The least loyal is fairly obvious, the Florida Marlins, regardless of some fairly high win seasons, the attendance does not go up.

Greatest Quarterbacks of Modern Era

My era begins with Joe Montana. I enjoyed the Pittsburgh Steelers and Oakland Raiders as a kid, but I didn’t really know what I was watching. So sorry, Bradshaw and Plunkett this list starts in 1980.

Ranking the top Quarterbacks based on Winning Percentage, Championship Game Record and Super Bowl Record. It’s all about the W’s. How do you see them shaking out? Would Brady top the list if he won the last one? Who am I missing?

Rank Quarterback Winning Pct Championship Superbowl
1 Joe Montana 117-47 (71.3%) 4-2 4-0
2 Tom Brady 87-24 (78.4%) 4-1 3-1
3 Peyton Manning 117-59 (66.5%) 2-1 1-0*
4 John Elway 148-82 (64.3%) 5-1 2-3

Fantasy Football 2007 Wrap-up: Receivers vs. Running Backs

For the first time in recorded history, I won our Fantasy Football league. woo hoo! Oddly enough, I had horribly running backs this year, sorry Maroney you may go undefeated but you were a fantasy bust. None of my running backs were in the top 20 based on yardage. However, my receiving core was solid with two receivers in the top 20, one in the top 5. Was that the difference or just luck? Having Brady as my starting QB didn’t hurt, and that was luck.

I thought maybe I also did better since you play three receivers instead of two running backs. However, in previous years I’ve had good receivers and never did well. So what is different about this NFL season, did this year prefer receivers over running backs, or did backs under perform across the board. Let’s look at some numbers.


Running Back Yards
L.Tomlinson 1,474 yds
A.Peterson 1,341 yds
B.Westbrook 1,333 yds
W.Parker 1,316 yds
J.Lewis 1,304 yds
Total 6,768 yds
Receivers Yards
R.Wayne 1,510 yds
R.Moss 1,493 yds
C.Johnson 1,440 yds
L.Fitzgerald 1,409 yds
T.Owens 1,355 yds
Total 7,207 yds

This is very different than seasons past, which the top yard carrier has been running backs. Last year even the 5th best running back had more yards than the top receiver


Running Back Yards
L.Tomlinson 1,815 yds
L.Johnson 1,789 yds
F.Gore 1,695 yds
T.Barber 1,662 yds
S.Jackson 1,528 yds
Total 8,492 yds
Receivers Yards
C.Johnson 1,369 yds
M.Harrison 1,366 yds
R.Williams 1,310 yds
R.Wayne 1,310 yds
D.Driver 1,295 yds
Total 6,650 yds

The top 5 rushers had +1,842 yds more than the top 5 receivers, that is a significant change to this year. Now yards aren’t everything, running backs tend to score more touchdowns and they also get yards receiving. So looking at the fantasy points the last two years:

Fantasy Points for 2007

Running Back Points
L.Tomlinson 293 pts
B.Westbrook 269 pts
J.Addai 222 pts
A.Peterson 222 pts
C.Portis 210 pts
Receivers Yards
R.Moss 280 pts
T.Owens 218 pts
B.Edwards 212 pts
R.Wayne 198 pts
L.Fitzgerald 188 pts

The top tunning backs still outscored the top receivers in fantasy points, but compare those fantasy points to 2006:

Fantasy Points for 2006

Running Back Points
L.Tomlinson 410 pts
L.Johnson 317 pts
S.Jackson 314 pts
F.Gore 249 pts
W.Parker 246 pts
Receivers Yards
M.Harrison 199 pts
T.Owens 189 pts
R.Wayne 181 pts
D.Driver 173 pts
C.Johnson 172 pts

The receivers scored about the same points, but the running back points took a significant drop from the previous year. Randy Moss and Tomlinson record years being the anomalies.

Did NFL teams rely on the pass more this year than the run? Yes. As you can see in this chart of total NFL yardage, by passing and rushing for the past 7 years. Note: 2001 there was 1 less team in the league, so total yardage is down. It was only Houston so not down too much.

NFL Yardage Passing vs. Rushing 2001-2007

The real question is, what will the NFL do next year and how should I pick my draft. I was hoping the chart would give an overall trend, but it doesn’t seem consistent enough. Oh well, I guess Brady and Moss as my first two picks next year wouldn’t be too bad.

Sept 23rd, 2012 – A-Rod becomes Home Run King!

Following up on my previous article with the prediction, Alex Rodriquez will become the all time home run leader with his 760th home run on Sept 23rd, 2012. He’ll pass Barry Bonds’ mark of 759 home runs also set on Sept 23rd, 5 years previous.

Prediction for A-Rod’s next five seasons leading up to the record:

Year Home
2007 58 522
2008 52 574
2009 53 627
2010 50 677
2011 45 722
2012 38 760

Home Run Kings – Barry Bonds, A-Rod and Pujols

Barry Bonds is probably going to break the home run record in the next few months. Though I’m not sure why people are making such a big deal about it, the record is going to be about as short lived as McGwire’s single season record. A-Rod is clearly going to be breaking Barry’s record in a few years and a good chance Pujols can break A-Rod’s record a few years after that.

Here are some numbers:

Alex Rodriquez started this season with 464 home runs at age 31. He has averaged 41 home runs a year for each full year he’s played. If he does the same for the next 7 years, he will hit another 287 home runs, giving him 751 career home runs at age 38. Bonds at age 38 was just past 600 home runs, and still at his physical peak. If A-Rod can perform in his later years as well as Bonds then he could expect an additional 150 home runs which would put him around 900 career home runs. If he falls off in his later years, maybe Alex will only hit 800.

Albert Pujols is on the same pace as A-Rod. In Pujols first 6 seasons he has hit 250 home runs, averaging 41 home runs a year and he’s still only 27 years old. The 2006 season was his best to date hitting 49 home runs, so it appears he is getting warmed up, which will make him down right frightful when he gets to his prime in his early 30’s.

But remember, Bonds has walked a major league record 2,432 times, once every 4 at bats for his career. If his walk ratio was on par with A-Rod’s which is once every 8 at bats, Bonds would have an additional 1,200 at bats. Considering Bonds’ career ratio is a home run every 13 at bats, that would have given him an additional 92 home runs, making it a bit harder for Alex to catch him. But at A-Rod’s current pace he might just hit 92 home runs this year.

The Odds of a Perfect Bracket

It’s March Madness time again which means time to fill out the tournament brackets. So I’m sure we are all wondering what the odds are to pick a perfect bracket, all 64 games picked exactly right.

The straight odds calculations is relatively easy, for each 64 games you must pick the right outcome out of the 2 possible outcomes (win or loss). So our Statisitics 101 class tells us that is two to the power of 64 (2^64) different possible combinations. Only one those will be the perfect bracket.

You have 1 in 18 quintillion chance to pick a perfect bracket

Oh and if you didn’t calculate that, 2^64 = 1.8 x 1019 or more precisely  18,446,744,073,709,551,616. This means you have a 1 in 18 quintillion chance of picking the perfect bracket. You have a better chance of winning the lottery two days in a row then picking the perfect bracket.[1]

However, I don’t buy the straight odds calculation. There has never been a #1 seed beat by a #16 seed, which is 4 games that are practically gimmies. The lowest seed to win the championship is an #8 seed, the lowest seed to make it to the final four is a #11 seed, to the elite eight #12 seed and sweet sixteen is a #14 seed.[2]

So it is relatively obvious that the rankings do give a distinct advantage to be able to pick a perfect bracket.

Here’s how I’m going to divide up the odds for the top seed to win a game in the first round:

 #1 vs. #16 = 0.95
 #2 vs. #15 = 0.80
 #3 vs. #14 = 0.75
 #4 vs. #13 = 0.70
 #5 vs. #12 = 0.65
 #6 vs. #11 = 0.60
 #7 vs. #10 = 0.55
 #8 vs. #9 = 0.50

Multiplying each of these gives us a 4% chance to pick a perfect round 1 for a regional bracket. There are four regionals so that would be 2.56 x 10^-6 (1 in 390,625 to pick a perfect round 1)

The second round is not quite as easy to give odds to, the #1 seeds would still have a distinct advantage over a #8 or #9, but the odds would be tough for say a #3 vs. #6. Let’s say the favored team for round 2 has a 55% chance of winning. For the 16 round 2 games this would be 0.55^16 = 7.0 x 10-5

Let’s say for the remaining rounds the odds are even, though they wouldn’t be but I want the calculation to be relatively conservative. So the remaining 15 games, actually 16 including the play-in game gives the odds as 0.50^16 = 1.5 x 10-5

Combining all the rounds gives us a total odds of 2.69 x 10-15 which is a 1 in 371 trillion chance, quite a bit easier than the straight odds but still a really really long shot.

So good luck with your picks, don’t feel bad if you miss a couple. :)

[1] – Assuming a 1 in 30 million chance of winning the lottery; to win the lottery two days in a row would be (3 x 10^6) * (3 x 10^6) = 9 x 10^12, or 1 in 9 trillion chance.
