BTW: I suggest reading that book!

Defensive Efficiency Ratio is a statistic used to evaluate team defense by finding out the rate of times batters reach base, on balls put in play. Basically, for every ball hit into the field of play, how likely is the defense to convert that into an out?

The formula for Defensive Efficiency Ratio is: 1 – ((H + ROE – HR) / (PA – BB – SO – HBP – HR)).

This stat is frequently used because looking at a team’s defense just by their fielding percentage is very misleading. Due to things like widespread defensive shifts, it is becoming hard to know exactly how good or bad a team’s defense really is. Even with the use of other defensive metrics like DRS and UZR, sometimes a really good or bad defender gets lost in the numbers for the team.

OK, if that sounds too complex, let’s just look at the DER of the top MLB teams:

These are the Top Teams
These are the Bottom Teams

So, the Dodgers are the best in baseball in DER and the Yankees are second. Is it coincidental that the teams with the best records in both leagues are #1 and #2 in DER? I think not. Defense wins championships, and DER is a very good way to measure how good a team’s overall defense actually is. The fact that the Dodgers are the best in baseball makes criticism of Muncy, Trea Turner, and Gavin Lux seem kind of hollow. Chill – all is good!

Tony Gonsolin Delivers in the Clutch

You can say whatever you want about Tony Gonsolin walking too many batters and making too many pitches, but dang, he is pitching very good in the clutch. First of all, he does walk too many batters and throws too many pitches, but let me remind you that he is 3-0 with a 1.33 ERA. His career EREA is 2.60. Yes, his walks are up – he has averaged 4.33 walks per 9 innings this year. It was 5.50 last year, but just 1.35 in 2020. If you have done it before, you can do it again. I think he will figure it out and cut way down on his walks, but I’ll take this too! I am a huge Tony Gonsolin fan. He has a very bright future. He does need to dial his walks back a bit and to do so, Doc has to keep running him out there. Pretty soon he will pitch into the 6th and 7th inning.

Give Edwin Rios a Chance

Give Rios a Chance!

All I am saying is give Rios a chance! Rios has a chip on his shoulder and he should alternate with JT as DH and play 3B. Throughout his short career, Rios has averaged a HR every 12.6 ABs! Let him play! You can’t sit this guy right about now.

Justin Turner Needed That!

It has been a rough season for JT with fans wondering if Father Time has caught up to him. After going 4-5 last night and looking pretty solid, I think Father Time needs to take a seat. JT has this covered… at least for this season… maybe he should play 3B a little less…

It is (Allegedly) Ryan Pepiot Time!

At 9:35 PDT ot 12:35 EDT, Ryan Pepiot is allegedly going to make his first start in The Show. The Dodgers sight does not list him yet. It says TBD, but that is because he is not yet on the roster. I assume he will start. Bring it, Pep!

Dodgers Food Trailer

I did this interview a couple of weeks ago with Chef Mike, who runs the Dodgers Food Trailer for the Great Lakes Loons. They are there for every home and road regular season and playoff game. They prepare three meals a day for approximately 50 people (players and coaches). Since games end late most evenings, they do not prepare breakfast. Many of their hotels have a complimentary breakfast anyway. However,…

Meet LAD 2026 Draft Picks 1-12

3 picks were High School players (2 SS and 1 OF). There was a college OF, college catcher, college SS, and 10 college pitchers. Of all the talk for a need for a catcher, the only catcher the Dodgers selected was Luke Bard, son of LAD bullpen coach Josh Bard. Bard was a 4th year senior from Houston Christian University. He is not a prospect, so the Dodgers are still…

It’s been a few days since I did this interview. We have evidently been working my son-in-law (the video guy) like a rented mule at US Water Systems. However, I am taking him to London with me in a few days, so maybe Watford will buy him a pint as a tip, but he’s a dang Red Sox fan, so there is that! I thought that it would be interesting…

Thanks for Your Service: Chris Taylor

I was going to do this post when Chris announced he was retiring, then he changed his mind, but since the chances of him ever playing for the Dodgers again are slim and non-existent, I will go ahead with this post. He unretired, went on the IL, then decided to call it quits on May 24th. Taylor was born in Virginia Beach VA on August 29th, 1990. He attended Great…
